Best 13 Tools To Test JavaScript Code

Swastikayadav — Wed, 15 Mar 2023 08:21:52 +0000

Unit and functional testing are the prime ways of verifying the JavaScript code quality. However, a host of tools are available that can also check code before or during its execution in order to test its quality and adherence to coding standards. With each tool having its unique features and advantages contributing to its testing capabilities, you can use the tool that best suits your need for performing JavaScript testing.

Considering the sheer number of JavaScript tools, choosing one that is right for you can be challenging. But an easy way to smoothen the process is to test JavaScript code in a browser. Yes, you can test your JavaScript code directly in a browser. To do this, you can use a variety of tools.

This article lists the best 13 tools to help you test JavaScript code in browsers.

Why test your JavaScript code?

As of now, the majority of websites use JavaScript as their client-side programming language. With HTML and graphical elements integration, advanced plugins like Silverlight or Flash, and the Document Object Model (DOM), JavaScript has maintained its supremacy in dynamic web development.

A recent survey by Statista shows that JavaScript will be the most popular programming language in 2022, with over 65% stating they use JavaScript and less than 55% using HTML/CSS.

Since agile development and rigorous integration have become a non-negotiable part of the software development process, continuous testing of the developed components has become crucial. The same goes for JavaScript. With it being extensively used in front-end and back-end components, it’s important to test your JavaScript code during the initial software development cycles.

Popular agile development methods like Behavior-Driven Development (BDD) and Test-Driven Development (TDD) work the same way, i.e., testing components as a fundamental building block.

Consider yourself working on a JavaScript code block. Wouldn’t it be better just to test it in a browser, without any separate installation on your local system? But that too dramatically depends on the tool or framework you choose for testing the code.

As JavaScript is a dynamic language (weakly typed), it becomes difficult to debug or test JavaScript code. Hence, you need to smartly choose one of the many tools, frameworks, and techniques to test JavaScript code in a browser.

Test your native, hybrid, and web apps across all legacy and latest mobile operating systems on the most powerful Android emulator online.

How to enable JavaScript in a browser?

As JavaScript is a scripting language that runs on a visitor’s browsers, almost every browser nowadays has to provide support for JavaScript pages. Typically, browsers come with the support of JavaScript pre-enabled. However, you can enable it manually if that’s not the case. In this blog on how to test JavaScript code in browsers, we will continue with Google Chrome as our primary example:

On your Google Chrome window, navigate to the three dots menu and go to Settings.
From the left sidebar, select Privacy and security, then Site settings.

Click on JavaScript.

Select the radio button that says: < > Sites can use JavaScript.

And you are done!

Now, you can view and debug JavaScript code for a webpage in your Chrome browser in two ways:

When your JavaScript code is wrapped within the HTML file, press the Ctrl + U keyboard buttons simultaneously.

When you have a separate .js file, right-click on any area of the web page and select the Inspect element option from the menu.

Let’s say you want to view or debug JavaScript for the Google landing page. It looks something like this.

You can surely debug your JavaScript logs with this method. Still, you need to perform proper end to end testing of your JavaScript code in the browser with the tools mentioned in this guide without relying on frameworks like Jest, Mocha, etc.

Before getting started with the tools, let’s see what tests you can perform.

In this tutorial, learn what is Regression testing, its importance, types, and how to perform it.

What type of tests can you perform?

Software testing is vast, but you must run these three tests for your JavaScript code.

Unit testing: This test works on the divide and conquers principle. Unit testing checks the performance of an isolated unit, i.e., a function or a class. As most programs involve interaction between various functions, classes, and modules, dividing a code into isolated and independent units is easy. You can also split these into server-side units and client-side units.

Integration testing: This type of testing acts as a complement to unit testing. Integration testing mainly focuses on how different components or units interact during the test execution. The functionality may fail once all the units/modules are put together, even though all the modules passed unit test cases successfully. Integration testing is used to identify and eradicate such instances.

End to end (E2E) testing: Once you’ve tested units and modules individually, the next step is to conduct an end-to-end test. E2E tests allow you to run a full functionality experience that includes both the front-end and back-end components. These tests automate user actions like mouse clicks and inputs. However, E2E tests are trickier to execute. Generally, they require dedicated automated testing frameworks.

Key Elements of an Effective Test Automation Strategy

Swastikayadav — Fri, 21 Oct 2022 10:57:38 +0000

Software Testing has become a non-negotiable, if not the most crucial, aspect in software success as the world seeks software/applications for everything. Over the past years, Test Automation has proved to fasten the software development life-cycle. An effective test automation strategy establishes the foundation of success for a software.

A user has a lot of expectations from any software application. Creating an application or software and then releasing it to the public is not a piece of cake. What if it has bugs, fails, does not work as expected? To make things worse, it can face security breaches. To ensure flawless working and security of the software application, automation testing is required.

By incorporating an effective test automation strategy, you can ensure a bug-free application. But, how to implement that? One may think of hiring more testers and moving forward with manual testing instead. But, hiring more testers isn’t cost-effective. Second, manual testing alone can’t possibly figure out all the scenarios or test functionality as deep as automation testing.

According to the statistics above, 42.5 percent of firms consider automation testing to be an important part of their quality assurance process. So, if you are testing applications manually, you can consider switching from manual testing to automation testing.

Hence, automation testing emerges as a definite inclusion in a software development life cycle. As the software and the team level up, an unchallengeable need for the right automation testing tool and test automation strategy arises. This article will demonstrate some of the key elements of an effective test automation strategy.

Test automation enhances your processes, saves you time and money, and leads to higher-quality software. However, you can’t just dive in and expect the automation to deliver the results you desire. If you want your releases to run successfully, you’ll need a clear strategy in place. All the benefits of automation testing may backfire without a test automation strategy. Hence, in order to inculcate automation testing and get a robust, better-planned development life cycle, one needs an effective test automation strategy. Let’s discuss the key elements of an effective test automation strategy in detail.

Strategy for a successful test automation

In automation testing, a cost-effective test automation strategy with a results-oriented approach is always the key to success. An effective test automation strategy will assist businesses in keeping up with the market and avoiding major technological failures. Automation testing strategy also incorporates the use of tools and pre-written scripts to perform tests at various levels.

Planning the development life cycle with a strategic test automation can boost the success rate of software. The strategy towards test automation should be result-oriented, defining all the key metrics of the software.

The purpose of a test automation strategy is to find, communicate, and audit the risks, defects, and even the capabilities of the software being tested. For an effective test automation strategy, one must understand its life cycle. Let’s explore more!

The automation testing life cycle mentioned above is nothing but a list of key elements to an effective test automation strategy. So let’s have a clear view.

Run Selenium, Cypress, and Appium tests on LambdaTest to scale with the demand of your website and web apps.

Key elements of an effective test automation strategy

An effective test automation strategy provides a comprehensive, reusable, and sustainable framework for the entire software development cycle. In this section, I will focus on some key elements of an effective test automation strategy.

A goal-oriented strategy

We all plan and strategize when we have a goal to achieve. Without a goal or an endpoint, one cannot prepare a strategy. Similarly, an organization or a team works on a software with a goal to achieve. Strategies are developed in order to reach the goal.

The test automation strategy must result in the desired endpoint. Decide on objectives that are achievable. With that in mind, building the testing strategy to achieve the objectives becomes easier. As they say, Destination then Route!

Automation Feasibility Analysis is the first step of the test automation life cycle. It is not possible to automate every software test. As a result, do an automation feasibility analysis to determine which tasks can be automated and which testing scenario you should not automate. For example, you can consider the following aspects to automate –

Testing across multiple interfaces and devices.
Repetitive test cases such as login and entering OTPs, captcha.
Processes working on multiple inputs, such as filling forms to test validations.
Tasks that are time-consuming and difficult to test manually.
Asynchronous or Batch processes that are time-bound.

Automation feasibility analysis analyzes all such scenarios. Basically, it is about figuring out — What tests can be automated?

When the functionalities to be tested by automation are defined, one can decide the right tools and strategy to inculcate. This brings us to land with an effective test automation strategy.

Defining the test approach

After analyzing the result, when a user wants to achieve and know the possible test cases to automate, the next step is to plan the approach. Let’s say you have an idea of what must be done, and all you have to do now is figure out how to get there. In this case, the first step is to figure out:

What needs to be included in the automation test?
How is the team planning to execute the automated tests?

Defining the test approach includes allocating the right framework and deciding on proceeding with various testing types. It also includes deciding on the execution order of multiple testing types, such as integration testing, unit testing, etc. This is where the Automation Testing Pyramid comes into the picture. The testing pyramid guides to choose all possible tests to include in the test automation strategy and the order of execution.

Strategizing the execution of different tests, their frequency, role, and time results in better and more accurate outcomes. For example, assume you have developed software that includes a login page. You have used form validations to receive standard inputs from the user. Now, at the time of testing, how will you proceed? What tests will you include?

This shows the importance of automation testing and the correct test approach. It also covers various test case design elements. But before that, setting up a test environment takes higher priority. However, one must know what to test and the respective test plan.

Setting up tools and test environment

Not having the right set of tools/frameworks and moving forward without a test automation strategy takes a toll on them. Although automation testing highly benefits a software development life cycle, sometimes it becomes tedious to choose the right set of tools.

But, how to choose the right set of tools?. With some considerations, one can easily choose the right automation tool for themselves. However, choosing a test automation tool involves the analysis of budget, requirements, team experience, etc. Below are the points one should keep in mind while choosing the tool for test automation strategy.

Decide the type of framework and tool

The market is full of test automation frameworks varying in the form of commercial, license, and open source. You can decide on the best test automation frameworks based on your preference and budget and classify them based on applications you are willing to test, e.g., web testing or mobile app testing.

For example, Selenium is the most preferred test automation framework when it comes to web automation, with 21.4% of the organizations preferring it over other frameworks under the same category. For mobile app testing, Appium leads the table, with 15.4% of organizations preferring it.

Looking to automate mobile apps on real devices, check out our video below –

Since a software is to be used on various platforms, it’s always better to choose the tool type that supports testing on most of the platforms and environments.

Choosing a cloud-based infrastructure platform like LambdaTest gives you access to more than 3000 real devices running on real operating systems to perform automation testing. In addition, this cross browser testing platform allows users to test public or locally hosted web apps on various browsers, operating systems, and devices.

Plan and research as to which tool can help you achieve better results, code and test coverage, prove to be the most cost-effective. Considering all the points, choose the one as per the requirement.

2. Consider the testing team

The project team also consists of testers, the people who are eventually going to use the test automation tool. It is important to consider the experience and size of the testing team. It is crucial to choose an easy tool for the testing team to use and handle.

It is highly important to choose a tool with which the testers feel compatible. Different testers have different experiences and tech stack choices. Considering the diversity in the team, it is important to choose a way that benefits all. Also, the testing team must sync with the chosen test automation tool.

3. Budget

What’s the budget? How much can you spend on automation testing? To be honest, financial restrictions are the most influential factor in such selections. However, because there are both free and paid tools, you can choose the one that best fits your needs and budget.

According to industry trends, the market size of Automation Testing crossed the $15 Billion mark in 2020. A few years back, organizations and teams spent not more than 15–20% of their budget on testing. But today, the numbers have risen to 30–45%. Most of the teams focus on automation testing; hence the investment keeps increasing. However, it is not mandatory to spend half of your budget on testing only!

If planned well, the average cost of automation testing falls lesser than manual testing at an organizational level. Maintenance cost, renewal/buying cost, training cost of the testers, etc., are the costs to be considered. Hence, it is better to calculate the ROI of automation testing besides deciding on the budget.

There may be a few more points to consider, at a personal or organizational level, while choosing a test automation tool. However, as discussed in the previous section, picking the correct set of tools is the third phase in the automation testing life cycle.

If you’re concerned about the financial impact of toll testing, don’t be. LambdaTest can cut this ratio down by a great margin. LambdaTest has a bunch of plans that cover various testing requirements. Pick a plan that matches your needs, get the best automated browser testing environment, and save your pocket! You pay only for what you use.

New Selenium IDE supports cross browser testing and parallel tests for automation along with record and replay function. Here’s why you shouldn’t miss out on it.

Designing test scripts and writing test cases

From the first three points, you can decide on the right set of automation tools based on your team’s compatibility, budget, software requirements, and test approach. The fourth key element of an effective test automation strategy is to design the test cases and test scripts.

People often confuse test cases with test scripts. Let us first establish the clear difference between both. What is a test script? Test Script is a program that tests a certain functionality automatically. Test scripts are generally written using a set of commands and some programming. If you are new to automation and wondering how to write your first test script, you can refer to the article on how to write test scripts in Selenium to know more.

What are test cases? Test Cases can be defined as a set of documents that consist of prerequisite conditions, test data values, expected set of results, etc., to carry out automation tests. For each functionality, a separate test case or a set of test cases is required. Each test case is designed to thoroughly test the functionality and pinpoint a bug or defect, if there is any.

A test case consists of several parameters, such as test case ID, description, steps, test data, expected result, test scenario, etc. The clearer and crisp the test cases, the easier it is to test and produce the desired outcome. There are some guidelines to design and write effective test cases; a few of them are listed below:

As every test case is designed based on a template, it is always the best practice to produce a template that can be used in multiple projects and scenarios. Furthermore, it cuts down a considerable amount of time and effort in the future.
As the team consists of many people, it is better if the test cases designed are easily understandable and to the point, as none wants to read heavy and baggy documents.
Write test cases using the flow of software and end-user in mind.

In case you have zero experience in writing test cases or test scripts, you can always refer to the test cases from other past or ongoing projects.

Test execution plan

After writing the cases, it is very important to plan the executions. Knowing when and how to perform automation tests is as important as writing the test cases. Devising a test execution plan includes inculcating top CI/CD tools like Jenkins, defining the steps in which test executions are to take place, and setting up version control.

It is very important to know the execution priority, as in, execution of individual test cases must take place first, then integration and regression testing should take place. Finally, every change and deployment must be followed by regression testing to confirm the changes are valid and working as expected.

Moreover, a few steps may be taken in or out depending upon the project requirements. Hence, after setting up the test automation tools and writing the test cases, a test execution plan must be devised to achieve the desired testing process and result.

It is better to plan the text execution in alignment with the software development life cycle.

Result and documentation

An effective test automation strategy is incomplete without a final touch. As a result, the findings of an automation test determine if functionality or software is working as expected. If it is, voila! Move it to the next step. What if tests fail or catch a bug?

In case the test produces a bug or a defect, there needs to be a proper flow of how it is to be solved or to whom it is to be assigned for further steps. It becomes much easier to handle when proper documentation is done.

A complete end-end documentation includes the test cases, list of tests to be done for functionality, results, result-analysis, assigner, assignee, workflow, etc., in the documentation. The process of including automation testing in a project may seem a bit tedious, but it is proper documentation and decision-making that get the job done better.

Conclusion

The first-time setup and planning of test automation may have loopholes and may also feel like a hectic task, but as time passes and things are learned, pieces fall into place! Once the initial steps are taken, automation testing can generate massive returns for you.

LambdaTest is the tool that gets your job done faster and easier. Along with supporting 35+ automation frameworks and all Selenium versions, it gives you the ability to conduct automation tests on an online device farm of 3000+ browsers and various operating systems.

The last two decades have seen massive growth in the IT industry. Numerous things went online with this growth, and to this day, almost every single thing we know of is online, either in the form of websites, web apps, and mobile applications.Today, more than 60% of the world’s population, i.e., Approximately 4.66 billion people, has daily access to the internet.

Now, when it comes to accessing a particular thing on the internet, people have multiple options. The competition to grab the customer is higher than ever and increases every day. You may create a top-class product that can easily compete and beat the rest, but a small overlooked aspect can cause you huge damage.

Suppose you hired a great team of developers who create a top-notch web app for you. But how do you classify it as top-notch? They show you a demo, and you get it right on your browser (say Chrome), but that’s not it. You don’t know who is going to access your web app and from which browser. What if it doesn’t work on Internet Explorer or Safari? You won’t know; the customer will switch to another product. How can you prevent that from happening? How will you retain the customer? The answer is cross browser testing.

In this cross browser testing tutorial, we will deep dive into various aspects of cross browser testing, including why cross browser testing is important to your business.

So, let’s get started!

What is Cross Browser Testing?

A website or web app contains multiple components, from texts to images and videos to infographics. Cross browser testing is a testing method that verifies if a website or web app performs across various browsers and environments gracefully.

This testing strategy ensures that all the components, i.e., text, images, videos, etc., of a website or web app are working as expected. Customer experience is the most important aspect of a product or company. Hence, you need to be sure if your product passes cross browser compatibility.

You need to ensure this compatibility majorly complies with these two aspects:

Browser and Operating System: People around the globe use different devices with different operating systems and browsers*.* Hence, you must ensure that your product works the same in every environment, such as Safari for Mac, Chrome ; Firefox for Windows, Linux, etc.
Different devices and Screen resolutions: Devices such as Mobile, Desktops, Tablets, etc., come in a lot of shapes and sizes. What works for your 5-inch screen might not work for a 10-inch screen.

In short, cross browser testing is non-functional testing where the product (website or web app) is tested across a number of environments and devices.

This smoke testing tutorial covers what smoke testing is, its importance, benefits, and how to perform it with real-time examples.

Why Cross Browser Testing is important?

Within the last ten years, we all have seen a surge in online services and products. Every day starts and ends with a business going online. Customers today have almost everything within their palms, and the competition is higher than ever. There is also a difference between each customer — Perspective and Taste. The same is the case with browsers. Different browsers may have different perspectives. The components rendered may not be viewed the same across all environments. Hence, this is why cross browser testing is important to your business.

See it from a customer’s perspective — Say you have been trying to access an application on your Chrome browser, and it hasn’t been working the way you want it to. What do you do? You will seek the help of another browser, or even worse, you’ll switch to another service or product.

Imagine this case again from the product owner’s perspective. How would you feel about it? Isn’t this a bad customer experience? Won’t you lose a potential customer? However, to avoid such ‘avoidable’ circumstances, you need to incorporate the following –

1.What all browsers and environments do you support

Being the service/product provider, it is your duty to practice transparency with the customers. You must have seen many companies and products deliberately mentioning the platforms they are available on.

2. Perform Cross Browser Testing

Now that you’ve explicitly stated the platforms you are available on, you need to ensure that everything works perfectly fine. If it doesn’t, it can cost you and your company the name and credibility.

There are multiple products and platforms you can look over for cross browser testing. Cloud-based cross browser testing platforms like LambdaTest provides an online browser farm of 3000+ browsers and OS combinations to users already installed and ready to be used on their infrastructure. If you are stuck anywhere, you have 24×7 support too!

But why cross browser testing is important to perform? Because the customer is the owner. Every aspect of your business is entirely dependent on the customers. Today, they have innumerable options for everything out there. With so many options available at their fingertips, people have become impatient. Even a slight delay or inconvenience can make them switch to another provider.

Before you go out and launch your product, it becomes super-necessary to ensure cross browser compatibility. This compatibility check verifies if all the proposed components of the web app or website are rendered exactly the way they are bound to. This verification picks out any irregularities and also ensures that the end-user experience is not compromised.

Why do Cross Browser issues occur?

Now that we know why cross browser testing is important, it’s time to understand why cross browser issues occur in the first place. The answer is — Browser Engine. The engine is the most integral part of a browser. Every website, web app, or web page is rendered through the browser engine only. Whenever the URL is called, the browser engineer identifies the programming languages and frameworks used in the URL and renders the components.

But before rendering the component, the browser engineer interprets the components in its own way. Every browser interprets the components in its own way, and this difference in interpretation causes cross browser issues across different browsers. While some browsers catch the style sheets and JavaScript versions, others may fail to interpret those. Hence, it results in cross browser compatibility issues for the latter browsers.

Some common Cross Browser Compatibility issues

There are a bunch of options that can cause cross browser issues. These can be easily popped out with the help of cross browser testing. Following are some of the most common issues that arise during cross browsing environment –

HTML/CSS Validation

Different browsers and operating systems have different ways of handling code. The smallest errors, like forgetting a semicolon or not closing a tag, may behave differently in different environments. Some browsers may render the component easily, while others may throw errors or not show anything at all.

This can be pointed out with the help of cross browser testing. However, it is more efficient to use an HTML/CSS validator in the beginning. For example — W3C validator for HTML and Jigsaw Validator for CSS.

2. The DOCTYPE Error

This error may arise in old and outdated browsers. The DOCTYPE, in general, isn’t checked by most browsers, but the old ones like Internet Explorer (version 7.0 ; below) may throw errors for missing it out. This is because browsers have two modes of operation — Strict and Quirk mode.

Upon not finding the Doctype, browsers move from strict mode to quirk mode and continue the operation. But the browsers with older versions that do not support HTML5 will likely get confused and mark the page as unresponsive.

3. JavaScript Issues

We all know that JavaScript is ever-changing, but the browsers are not. Hence, cross browser compatibility issues with javascript arise when an outdated browser fails to acknowledge any newer JavaScript features.

If we are to recall one such feature of JavaScript, it is ‘Promise’ which isn’t supported in older versions of Internet Explorer.

4. CSS Resets

Each browser has its own default design layout. This layout is applied to each website that appears on the browser. But for a website to use its own CSS design, it needs to override the default layout of the browser. In case you don’t or fail to do that, the browser won’t render what you expect. This can cause cross browser compatibility issues.

This issue can be solved easily by incorporating CSS resets. It is a style sheet that resets the layout of a website or web app and applies the basic style to be overridden as expected. A few of the most popular CSS reset style sheets are HTML5 Reset and Normalize.css.

5.Need for separate Stylesheets

Most of the cross browser issues arise either from Stylesheets or JavaScript, and both of these occur because of older browsers. You don’t have control over people as to which browser they use.

The fastest way to tackle this issue is to use different stylesheets for different browsers accordingly. The use of conditional statements can ensure whether the correct stylesheet is used for each browser.

6. Not performing Cross Browser Testing

You can take care of each known issue beforehand, but you can never be too sure. Hence, no matter how much you are prepared or how many precautions you’ve dealt with, you mustn’t roll out the product without performing cross browser testing.

You must perform real-time cross browser testing on real devices. If you want to work smart and save time ; money, you can use LambdaTest cross browser testing platform. Cross browser testing tools like LambdaTest offer an online device farm consisting of 3000+ real devices running on real operating systems to perform automation testing and real-time cross browser testing of your product effortlessly. Moreover, you can test your public as well as locally hosted website.

Features to test while performing Cross Browser Testing

If your application or website is working fine on one browser, say Chrome, it doesn’t guarantee a proper execution on other browsers. It might not even guarantee smooth execution over different versions of Chrome itself. Thus, cross browser testing becomes important. But what all do you need to test? What features do you exactly need to check while performing this test? Let us find out:

1. Basic Functionality — Whenever you open a website or a web app, what are the first things you see? The key elements of the page — Heading, Images, Videos, Menu, Link, etc. These are the key elements that collectively form the initial look and feel of a website.

Form Validations are working as expected.
Inputs based on touch are working smoothly.
Menu and Alerts are working as designed.

2. Performance and Design — It is very important to check if your website is performing as expected. For example — Analyze the load time over multiple browsers, i.e., if your website loads within the desired time frame and if there is any delay.The design metrics include the testing of the graphical user interface (GUI) to ensure that the look and vibe of the application as a whole are positive. Testing for design also includes layout, font sizes, media queries, etc. to match with expectations.

3. Response — The ultimate revenue, feedback, success, and even failure, everything depends on your customers and their experience. Hence, it is super-important to test whether the proposed actions run smoothly on the user’s actions. For example — A specific filter or query by the user should load the expected results with an excellent GUI. Even a small glitch or compromise may cost you the customer.Seamless responsiveness testing of a website also depends on compliance with WCAG, i.e., Web Content Accessibility Guidelines. That is if your website is designed to serve differently-abled people as well.

In this System testing tutorial, learn why System testing is important and all the intricacies of the System testing process.

How do you select Browsers for Testing?

With the availability of countless browsers, devices, and operating systems, how to select what browsers you need to check for? Don’t even get started on permutation and a combination of browsers and operating systems, that’ll only double your pain.

However, you can narrow down your focus and build a more streamlined plan of selecting top browsers for cross browser testing.

You can niche down your options by using the following two criteria:

Based on Popularity: Everything across the world follows the 80/20 principle, and so do the browsers. More than 80% of the world’s internet traffic belongs to the top 20% of browsers. The same goes for operating systems, platforms, devices, and everything. This is one of the key metrics to look for when putting out a B2C product.
Based on Statistics: You need to know about your target audience. You can’t sell clothes at a restaurant where people come to eat. Hence, analyze the stats and find out what all browsers and operating systems are being used by most of your potential customers. If you already have a product or website out in the market, make use of those analytics tools like Google Analytics to figure it out.

Draft a Browser Support Matrix

One of the most important aspects of developing a website or web app is considering what all browsers and systems you are willing to support. Ideally, before development, you decide on a list of browsers that you are going to launch your website on. This list of compatible browsers with your website is called Browser Support Matrix or Browser Compatibility Matrix.

This list includes all the supported browsers by your website, mobile, and desktop versions, and operating systems. In most cases, this browser matrix includes a combination of browsers, operating systems, and devices.

But why do you need a browser support matrix? As I’ve mentioned above, you can choose browsers and operating systems based on popularity and statistics. This helps you narrow down your development and test cases to specific and desired sets of browsers and platforms. This is where the browser matrix comes into the picture. It helps you clearly plan and devise a roadmap for the development, testing, and launch of your website to the end.

How to perform Cross Browser Testing?

There are two ways to perform cross browser testing: The manual method and the automation method. There is a strong need for you to know when and how to choose a specific testing method and in which case you will benefit from Manual or Automation cross browser testing. Let me make it easy for you!

Manual cross browser testing

When starting out with cross browser testing, it is important to decide if or how much manual testing is required. To brief what manual testing is –

It is a software testing practice performed manually, of course, by testers or a team of testers by going to each browser and executing the test cases manually, noting down the results, following the bugs, etc. It really is tedious and tiring. Based on your project requirements, manual testing efforts may vary from hours to weeks!

What are the key steps of Manual cross browser testing?

Develop a strategy

You need to devise a manual cross browser testing strategy that aligns with your product goals. Determine what you need to test and where to test. After this, you need to make a list of environments, optimization steps of live tests, coverage, etc.

It is better if you come up with a shared testing platform where you and your team can collectively work towards the coverage goals. The most important part of this strategic planning is coming up with the infrastructure you want to use and move forward with.

2. Testing Infrastructure: Simulator, Emulator, and Real Device

The most important aspect is the selection of infrastructure where you want to conduct these tests. Do you plan to use real devices, emulators, or simulators?

Emulators and Simulators are virtual mobile devices. To be more precise, these are programs that let you create a desired mobile environment to perform your tests. Whereas, real devices are the devices that we see and use in our daily life.

However, while performing software tests, real devices are always resorted to at last.Simulators and Emulators allow you to run your tests inside virtual-software environments that are flexible and defined according to your needs. Although they both are used for testing, this doesn’t mean they are exactly the same.

Simulators basically create software environments and are implemented using some high-level languages. These do not form a part of or do not emulate the actual hardware required to run the foretold software.

Emulators, on the other hand, try to replicate all the hardware requirements along with the software requirements. An emulator is written using an assembly language. It won’t be wrong if I state that emulators form a middle base between simulators and real-time devices.

No doubt, manual testing can save you some money if you are not scaling too many browsers in the first place. However, the situation reverses when you are a large company and want to roll out your product on numerous browsers and platforms. This is where the second option, automation testing, helps you better.

A complete Manual testing tutorial covering all aspects of Manual testing, including strategies and best practices.

Automated cross browser testing

Unlike manual testing, automation testing takes much less time and effort. Automation testing requires minimum manual labor and can be performed efficiently with the help of automation testing platforms like LambdaTest. You get automated cross browser testing for thousands of browsers, operating systems, and their combinations.

Moreover, in cross browser testing where you need to test functionality over a combination of browsers, operating systems, and devices, it is more beneficial to automate it. Automation browser testing provides precise and faster results, no matter how much the case and how complex the environment.

Now, this is where the world’s most powerful automated testing tool, LambdaTest, comes to your rescue. It gives you a cloud Selenium Grid to conduct your automated cross browser testing on more than 3000 browsers, operating systems, and their combinations.

Conclusion

If we have to sum up this article on why cross browser testing is important, we established that any online business is entirely dependent on the customers and their experience using your product. One of the most common user experience issues occurs because of cross browser incompatibilities. These cross browser compatibility issues must be resolved beforehand, i.e., before putting forth the product in front of your customer.

Hence, this is why cross browser testing is important to be taken care of. You can’t bear the risk of rolling out your website or web app with a chance of a bad user experience. This may very well cost you lifetime customers or even your whole business. Therefore, get yourself a dedicated process for cross browser testing and launch your product with utmost confidence. And what tool is better than LambdaTest?

Complete Guide To Spring Testing

Swastikayadav — Wed, 19 Oct 2022 08:17:44 +0000

Software testing is a non-negotiable aspect of the software development life cycle. Setting up and moving on with software testing might be a tedious task. You or your team may feel stuck devising a testing strategy or picking up a testing framework. However, the major roadblocks are either related to methodology or framework.This article revolves around how to perform testing of spring applications.

Spring Framework supports your whole testing ecosystem. Spring framework best aligns with the Agile methodology of software development. As agile methods offer a better environment for developers and testers to perform Unit testing, this Java-based framework adds the moon to it. Spring also offers excellent support for integration tests.

In this article, we explore the Spring framework and how to test applications built using Spring and Spring Boot frameworks.

What is Spring Framework?

The Spring is an open-source framework based on Java. Released by Rod Johnson in June 2003, the primary purpose of the Spring framework is to provide Java applications with infrastructural support. It also eradicates various roadblocks that arise while testing Java-based in-container applications.

Spring as a framework is a wholesome body of codes and classes that developers and testers can use to tackle Java-specific problems and limitations in testing them. In the Spring framework, you do not need to create separate classes specific to Spring. This allows you to steer clear from getting dependent on the Spring framework. Hence, Spring is also called a non-invasive framework.

However, you can still create Spring-specific classes such as JNDITemplate, JDBCTemplate, etc. Spring, therefore, emerges as an overall solution for testing requirements for in-container applications.

Automated Functional Testing tests helps to ensure that your web app works as it was intented to. Learn more about functional tests, and how automating them can give you a faster release cycle.

How does Spring Framework work?

Programs based on JAVA EE are often very complex and involve heavy components. By heavy, I mean the components depend on the current operating system. This makes the application code interdependent. The term used for such conditions is — Tightly coupled, i.e., the application codes become tightly coupled to each other. This is when Spring Framework is not in use.

The primary weapon of Spring, or say the most crucial logic of Spring, is — Dependency Injection. This solves the problem of tightly-coupled architecture as it makes the application code decoupled. The whole meaning of dependency injection is to create such a pattern that, in turn, creates decoupled architecture.

The Spring framework also helps you tackle the testing problems based on methodology or framework. It can help you with the following testing needs. These are also called Features of Spring Framework –

Isolation

Your J2EE application may not support isolation testing without connecting to corresponding databases. However, you can perform isolation tests with the Spring framework by inoculating mock implementation testing. For example — Consider you have a service class depending on a domain class. Spring allows you to isolate that service class and perform the testing without worrying about database connections and domain dependencies.

Data Access

In case you have dependencies that can’t be worked out, you’ll always have the option to resort to Spring helper classes. These increase the dependency on the Spring framework but can provide you with the workaround for the data access hierarchy. You can work with helper class templates like JdbcTemplate, TopLinkTemplate, etc.

Transaction Management

Spring gives you excellent support to track and manage local and global transactions. An abstraction framework achieves this within Spring. This abstraction framework gives a wide range of transaction management, from declarative to programmatic.

Furthermore, the Spring framework provides excellent support for Unit and Integration testing (as we talked about before).

Software Testing Strategies and Limitations without Spring Framework

Let us first understand what exactly they are Framework-related blocks. Let us assume your project is going smoothly according to agile methodology, and most of the work is based on the J2EE architecture model. Software testing is mainly based on Unit testing and Regression testing. Unit testing, in particular, is super important to attain high code coverage, which can’t be performed in J2EE architecture.

Why so? Because the application server container is the core of the J2EE runtime environment. This makes it hard to perform Unit testing, which needs to be performed outside the container. Therefore, to thoroughly test and cover a J2EE-based application, it is necessary to deploy it inside the container. Here comes another catch — In-container software testing kills productivity. It is prolonged and can heavily impact the timelines of your project cycle.

There is no need to worry, though. This framework-related block can be easily solved by considering the framework Spring. Spring is an application development framework based on Java enterprise. It has the potential to support both Unit and Integration testing for your software. In fact, the main motive behind software testing with the Spring framework is to smoothen the process of Unit testing following the agile strategies.

Let us first understand the Software Testing types –

Unit testing

Let us get on with a simple example — Consider a piece of JAVA code having 1000+ lines. First of all, this violates SRP (Single responsibility principle), which states that a code module should only take care of one functionality. It is like the divide and conquers principle applied in software development.

Anyways, violating principles or not, you have this code now. How do you plan to perform Unit testing? It becomes complex to unit test this extended code and ensure proper coverage. No coming to the definition of Unit testing –

Unit testing is a software development process where units of software, application, or code units are tested independently to ensure proper working and desired results. In Unit testing, codes and functionalities are isolated to ensure accurate operations.

Unit testing also favors quick testing of new changes or methods to the existing code. Manual Unit testing is done by developers at the early stages of the project and also saves a lot of time and effort in the later stages.

Unit testing, an essential component of Test-Driven development, has three stages –

Plan: Preparation of unit test and review.
Design: Test cases and scripts are made.
Test: Code is unit tested.

One of the most popular frameworks for Unit testing is JUnit. In JUnit, you can use Mock Objects and initialize objects with the new keyword. You also don’t need to worry about in-container resources, JDBC connection pools, JNDI, etc. The mock Object testing technique makes it easy to perform isolated unit tests.

LambdaTest offers free JUnit certification for Java developers that can help you advance your career in Java development and testing.

The following is a glimpse of the JUnit Certification from LambdaTest.

Integration testing

Testing modules integrated together is vital to test them in isolation. If a class or module works fine alone, it doesn’t guarantee a perfect result when combined or integrated with other modules. Hence, the need for Integration testing arises. Integration testing is the type of testing where specific modules and classes are combined with being tested as complete functionality.

Understand it like this — A team of developers develops your project’s different functions and modules. Each developer works on different functionality and develops different modules (Agile Software Development methodology). In Unit testing, we test those individual modules in isolation. The purpose of Integration testing is to ensure whether these different modules work fine while combined or merged.

Integration testing test cases are designed mainly to focus on the interaction that happens between modules. As the individual functions are already tested in Unit testing, Integration testing tests the linking between these individual functions and modules. One can also think of Integration testing as complementary to Unit testing.

Through this usability testing tutorial, you will learn how usability testing is a great way to discover unexpected bugs, find what is unnecessary or unused before going any further, and have unbiased opinions from an outsider.

Regression Testing

This testing practice comes into the picture when any code changes or when the software package is deployed to production. This ensures that the complete functionality works as expected. Better consider it as the final step of verification of whole product functionality.

Several more testing strategies are incorporated in a software development lifecycle. For example –

Load Testing: These tests verify the scalability of the proposed software.
DB Testing: These tests ensure whether the data access levels are working as expected and data integrity is taken care of.
Profiling: These tests ensure proper garbage collection and detect any memory leaks.

Despite being highly useful, all these testing methods may or may not work in specific environments. For example — Applications based on J2EE architecture require specific frameworks to support different forms of testing. In this article, we are talking about how to perform Spring testing.

Spring Testing with Spring Framework

Shown below is how to run Spring web tests using the Spring framework.

Unit testing with Spring Framework

If you follow the standard Spring Framework architecture, the dependency injection and use of Mock Objects can make Unit testing super convenient for you. Testing individual code and modules, i.e., isolation tests, is easy to execute using Mock Objects.

Unit tests, in general, execute fast, hence eradicating the need to set up any runtime architecture. Spring testing adds the moon to these by providing test support classes and mock objects. Spring has several packages to support mock objects, like JNDI, Servlet API, etc.

Test Support Classes for Unit testing

The Unit testing support classes in Spring Framework are divided into the following two categories –

General Testing Utilities
Spring MVC Testing Utilities

For general testing utilities, you get the org.Springframework.test.util package. This package offers multiple general testing utilities that you can use in the Unit and Integration testing. This package considers all the scenarios that you may come across in writing unit test classes. For example –

ReflectionTestUtils: It is a reflection-based method used in scenarios where there is a need to play around with constant value, invoke or set a non-public method, or use call-back methods.

Now for Spring MVC testing utilities, you’ll use the org.Springframework.test.web package that contains the ModelAndViewAssert method. This can be used with JUnit to perform unit tests incorporating the ModelAndView objects.

Integration testing using Spring Framework

The Spring-test module within the Spring framework provides excellent support for Integration testing. The pain of connecting to another infrastructure or requiring deployment to an application server is high.

The proposed Spring-test module helps you fight that pain. It includes the org.Springframework.test package that provides various necessary classes for Integration testing.

The Integration testing support provided by Spring has the following goals –

Manage Spring IoC container caching between tests.
Manage the supply of base test classes specific to the Spring framework.
Provide and manage Dependency Injection.

Integration tests using the Spring framework can be executed just like JUnit tests. Integration tests include testing at an integrated level rather than isolated. Hence they are generally slower. But when using the Spring framework, NO! They are not.

Spring-specific integration test classes present in the org.Springframework.test package cover almost every corner.

Following are some of the base integration test classes provided by the Spring framework in this package –

TEST CLASS	WORKING
AbstractJpaTests	This class tests the JPA functionality and offers an instance called EntityManager that can be used to call these JPS methods.
AbstractModelAndViewTests	This class is used to test the two layers in the application, i.e., the presentation and controller layer.
AbstractAspectJpaTests	Extended by the AnstractJpaTests class, it can be executed for LTW (Load-time weaving).

Spring Testing Using Spring Boot

With Spring Framework, it becomes much easier to run Spring web tests and more efficient when Spring Boot comes into action. Spring boot is a Spring-based framework that allows fewer dependencies and faster bootstrapping than Spring itself. It offers an immense set of features for performing Unit and Integration testing. The Spring-boot-test module and Spring-boot-test-autoconfigure configuration help you run the Spring boot application test.

You can use the following support libraries to pull required testing dependencies –

JUnit: This is probably one of the best Unit testing frameworks you’ll get hold of. It provides you with an all-around testing environment, especially for developer-side testing. Junit is a java-based test framework and works wonders in the test-driven development cycle.

Mockito: As the name gives away, it is a Java Mocking Framework.

JSONassert: This support library helps write unit test cases based on JSON.

Spring Test: The utility that provides support for Integration testing.

Spring boot comes with comprehensive support for writing and executing Spring boot web tests. From annotations to use in test classes to individual test-specific requirements, it gives you all. Do you want an example? Here we go –

To get on with testing features, you need to import the org.Spring boot.app package. You can also use @SpringBootTest annotation. This annotation is often used along with @RunWith(SpringRunner.class). These, in association, load the application context and many more behind-the-scenes requirements. However, the @SpringBootTest won’t initialize the server by itself. You need to work with a mock environment for that.

Here is a code snippet for testing Spring boot applications –

package org.Springboot.app;
import static org.Springframework.test.web.servlet
   .request.MockMvcRequestBuilders.*;
import org.junit.*;
import org.junit.runner.RunWith;
import org.Springboot.app.controller.*;
import org.Springframework.boot.test.autoconfigure.
   web.servlet.AutoConfigureMockMvc;
import org.Springframework.boot.test.context.SpringBootTest;
import org.Springframework.test.context.junit4.SpringRunner;
import org.Springframework.test.web.servlet.MockMvc;
import org.Springframework.test.web.servlet
   .setup.MockMvcBuilders;

[@RunWith](http://twitter.com/RunWith)(SpringRunner.class)
[@SpringBootTest](http://twitter.com/SpringBootTest)
[@AutoConfigureMockMvc](http://twitter.com/AutoConfigureMockMvc)  // Mock environment
public class ApplicationTestingClass {

The above code snippet must have given you a clear idea of how to write test classes using the Spring-boot annotations. Despite sounding complex, Spring testing is fairly easy. As you have the option to integrate multiple frameworks and utilities, Spring testing (Unit and Integration testing) becomes easy and can be performed within in-container applications with accurate outcomes.

Black box testing? Don’t worry; we will be covering what is Black box testing, merits, demerits, types & techniques.

How to test Spring applications on the cloud

In the earlier section on Spring testing, we explored different ways to test Spring and Spring boot applications. Now let’s see how to test your spring or spring boot applications utilizing cloud-based testing platforms.

Top Cross Browser Testing Trends [2022]

Swastikayadav — Tue, 18 Oct 2022 13:53:35 +0000

With the rapid evolution in technology and a massive increase of businesses going online after the Covid-19 outbreak, web applications have become more important for organizations. For any organization to grow, the web application interface must be smooth, user-friendly, and cross browser compatible with various Internet browsers.

For this purpose, it is required to focus on cross browser testing to bring a shift in web development trends and consider it more of a necessity than just an addition to the product life cycle process.

Back in time, software testing was just about finding errors in a product to improve product quality. But today, in 2022, with the wide range of browsers and browser versions available, the range of software testing has broadened. To experience the transformation and provide users with a better experience while surfing on different browsers, it becomes essential to overcome the cross browser testing challenges on priority.

In this article, we will discuss a few of the top cross browser testing trends for 2022, which will help you choose the right cross browser testing approach.

However, before diving into the cross browser testing trends, let’s understand cross browser compatibility.

Now, you can run your Selenium Automation Testing scripts on the LambdaTest cloud grid. Test on 3000+ desktop & mobile environments. Try it for free.

Cross Browser Compatibility

For understanding cross browser compatibility, let’s consider a situation in which you’ve started a small online business, and it grows with time. In the beginning, you didn’t think about the layout and view of your website in every browser. Still, as the traffic grows, you get to hear about its inconsistency and instability on different browsers, which can be a significant obstacle for you at the user experience level for your business.

Let’s say that your web app performs well across Chrome and Mozilla Firefox. Still, it doesn’t look attractive, opens with the wrong indentation, and works inappropriately across other browsers like Opera, Apple Safari, Microsoft Edge, etc. What happens if someone uses a different browser to access your site? There’s a good chance you’ll lose a potential customer due to a poor user experience, which is something you don’t want to happen.

As you can see from the above image, every browser has a significant market share worldwide; hence, it cannot be ignored and must be considered in your cross browser testing strategy. The same applies to browser versions, as the market is fragmented. Hence, considering browser versions is equally important while creating your browser list to perform cross browser testing.

When this can be a problem for even a small business of yours, in this case, imagine what role it can play in heavy and high traffic web applications. Therefore, cross browser testing is always required to check the website’s browser compatibility across all the required browsers, for which a cross browser compatibility testing tool can be used. In addition, most companies accept testing as an early activity in the software development life cycle, which wasn’t the case earlier.

Traditional methods of cross-browser compatibility testing are also available. Even so, they’ll take a lot of time, resources, effort, and money because you’ll have to test your web app across a variety of browsers on computers and mobile devices.

Organizations with low resources and budgets face multiple cross browser testing challenges. It demands a robust system to test new features and essential business processes to help reshape the application to get the required results. Thus, the better solution to tackle the problem will be to choose a cross browser testing tool for browser compatibility testing.

Top Cross Browser Testing Trends for 2022

The cross browser testing industry is constantly evolving, driven by shifts in user behavior and the launch of new device types and browsers. At the beginning of 2022, we are here after a careful analysis of the market trend and the latest prioritized technologies. These technologies have begun to emerge as software testing trends, and they have the greatest potential to grow at a considerable rate by 2022. Let’s see the cross browser testing trends and why they are essential this year.

1. Cloud-Based Cross Browser Testing

Cloud testing makes use of a third-party service provider’s cloud computing capabilities to test software applications. This can apply to cloud resource testing, such as architecture or cloud-native software as a service offering, as well as the use of cloud technologies as part of a quality assurance plan. It benefits from low cost, high scalability, and easy availability. It allows web and mobile testing in a variety of scenarios and on numerous machines without having to construct your own infrastructure.

Needless to say, the rising popularity of cloud testing has given rise to a slew of cloud-based testing tools in the market. Cloud-based tools can access an array of browsers and devices so that we can execute tests across all required systems.

Organizations can benefit from cloud testing in a variety of ways. This can provide availability, optimal performance, and protection of data while minimizing downtime of the underlying infrastructure or platform for enterprises testing cloud resources.

Currently, there are hundreds of devices on the market, each with its own resolution and browser, making the setup of such a large testing infrastructure prohibitively expensive. As a result, most businesses and individuals are turning to cloud-based cross browser testing platforms.

As per Statista, the Cloud applications market size worldwide is expected to reach 168.6 billion U.S. dollars by 2025.

In 2022, we will see an increasing demand for the use of cloud frameworks. There are multiple products and platforms you can look over for cross browser testing. Cloud-based cross browser testing platforms like LambdaTest provides an online browser farm of 3000+ browsers and OS combinations to users already installed and ready to be used on their infrastructure.

Here are some of the features of cloud-based cross browser testing tools:

Infrastructure and maintenance
Cost-effectiveness
Availability and collaboration
Scalability
Faster testing
Simplified disaster recovery

In this tutorial, learn what is Regression testing, its importance, types, and how to perform it.

2. AI-Powered Cross Browser Automation Testing

Cross-platform testing is the practice of testing across browsers, OS, and gadgets to confirm that the software works correctly. Cross browser testing involves web applications that may need to be compatible with multiple browsers, devices, and platforms. The prevalence and rising acceptance of AI and machine learning (ML) have given QA professionals, notably those in charge of cross-browser testing, new capabilities.

Automation testing is any method that allows you to execute your tests without the need for human interaction. Manual testing has been used in the past. A person goes through a series of steps to see if things are working as they are expected. An automated test, on the other hand, is created once and then run whenever you need it.

By increasing people’s skills and capacities to interpret real-time data, AI and ML help enterprises minimize testing gaps. Furthermore, if scalability and software quality are top requirements, AI/ML are beneficial technologies.

Transitioning to automation reduces testing time while also reducing the risk of errors. Furthermore, intelligent automation, such as AI/ML, can deliver significant business benefits such as revenue generation, execution speed, accuracy, compliance, and cost savings.

Watch this webinar to learn about enterprise-wide actionable strategies, the dos and don’ts of automation testing and DevOps tooling that will help you improve the release and test velocity.

Perform browser automation testing on the most powerful cloud infrastructure. Leverage LambdaTest automation testing for faster, reliable and scalable experience on cloud.

AI can assist in the creation of test scripts, the improvement of test analysis, and the removal of the requirement for routine maintenance. QA experts may eliminate human error and reduce the time and effort required to test a scenario by incorporating AI into cross platform testing.
Developers have been automating unit testing for a long time. That is tests that determine whether a function is functioning appropriately. These enable automated testing of modules or entire applications.

These frameworks enable a test script to interact with your UI and simulate user actions. For example, they enable you to locate and click a particular button. Alternatively, find a text entry box and correctly fill it out. They also allow you to double-check that the test was accurately completed.

Automation testing aims to reduce the amount of time and effort required for recurring tasks such as regression testing. Even writing the test cases and scripts, however, necessitates manual work. How can we eliminate even a smidgeon of human effort, given that clients currently want faster delivery? Artificial intelligence’s most recent and potent concept comes with a solution.

There are some factors to consider when deciding whether a test can be automated. Here are the most important ones:

Improved accuracy

When manually testing software, even the most experienced testers might make mistakes. However, automated testing can save the day. AI can help testers create more effective test automation strategies and test scripts, and uncover new ways to provide the best possible user experience. By boosting accuracy and speed, technology can make testing easier.

Faster test creation

Artificial intelligence can help test recorders perform better. Intelligent test recorders are capable of producing superior test scripts in a much less amount of time. Software testing AI tools can aid in the recording of user sessions and the identification of missing tests in a path. Such tools can add a test to the test library if none is identified.

Faster time to market

Manually running tests is time-consuming and inconvenient, especially when a development team frequently changes the software source code. AI can conduct and redo automated tests faster and at a lower cost, allowing apps to be released sooner.

The most significant benefit provided by AI-powered technologies is the ease of maintenance. They are more capable of healing. These tools continuously scan the code for changes or patterns. When they discover a change in the application, the tool automatically updates the test script. Machine learning and artificial intelligence are used by tools like LambdaTest to authorize, execute, and maintain automated tests.

Looking at their acceptance, they are going to be highly popular automation testing trends in 2022. You won’t have to worry about maintaining or altering your scripts in the future, even if your application grows to thousands of test cases. You can delegate the task to AI.

3. Automated And Codeless Cross Browser Testing

Cross browser testing has the key benefit of giving a tester more test coverage, which can assist avoid cross browser compatibility concerns. However, the drawback of cross browser testing is that it necessitates the creation of distinct scripts for each browser and the testing of each combination independently.

This test procedure is time-consuming since it involves ensuring that an application works across multiple access points and a variety of device and browser types. This can be expensive and difficult to do, and here is where automated and codeless cross browser testing tools come into play. It is possible to make cross-browser and cross-device testing more efficient, and one method is to use a no-code tool to automate the process.

By reducing the amount of time spent on coding in manual testing, codeless automation frees time for both testers and developers to focus on product development and innovation to help accelerate testing in the SDLC.

Selenium is the most widely used technology for automated web application testing. Its popularity will continue to grow because:

It is open-source and free to use.
Multiple browsers and OS systems are supported.
Multiple languages are supported, including C#, Python, Java, Perl, PHP, and Ruby.
The IDE includes tools for debugging, recording, and editing test cases.

However, in 2022, Selenium will undergo a transformation due to the growing use of AI and machine learning. Machine learning and artificial intelligence (AI) both attempt to provide alternatives to monotonous and error-prone tasks. These automation tools are powered by Selenium and AI and provide codeless automation testing support.

With the latest automation testing trends, testers can now automatically generate a self-healing Selenium code. As I previously stated, AI-powered tools can simply detect and modify a modification in the application’s script. With these tools, testers will no longer have to worry about test case maintenance.

What Is Test Environment? A Guide To Managing Your Testing

Swastikayadav — Mon, 17 Oct 2022 10:20:07 +0000

No software can sustain itself in the market without testing — Do you agree? Yes? That’s cool! Testing is crucial in any software development life cycle. With an ever-growing rate of software products, do you know that almost 77% of testers have worked on projects related to web testing in the year 2019? With an estimated 25 billion Internet-oriented devices as of 2021, this percentage should have increased.

A robust testing methodology is all it takes to combat bugs. However, a weak testing methodology can lead to some bugs that may not be cosmetic but will result in the software being unable to fulfill the user’s needs.

To fulfill the user’s needs and make the testing task easy, the term “Testing Environment” came into the picture. A testing environment is nothing but software and hardware configuration allowing testing teams to run perfect test cases. Do you want to enable test execution with the right software, hardware, and network configuration? A test environment is your go-to place.

In this post, we are going to explore what is test environment and its major features and elements related to a test environment.

What is Test Environment?

A test environment is a host/server that allows you to run the test cases according to the user’s or software’s requirement to be tested. It sets up the host and integrates hardware (RAM, processor speed), software, and network configurations. Test environments are used to test and identify the application for bugs and find a possible fix for the same for the smooth functioning of the application for the user. A cross browser test environment is a perfect example of a test environment for testing on different browsers and browser versions.

The test environment is used by the testing teams to check the quality and impact of the application before handing it to the user. It can test a specific part of an application using different configurations and data setups. It’s an essential part of the agile development methodology.

When you start learning about the test environment, you need to understand organizing the testing environment. The easiest way of organizing test data is through automation, and by building and deploying the automation in place, you can successfully manage environments.

Key Steps in the Testing Process

Before working on your testing environment, you must look into a few factors and processes. It’s a must to understand the testing process to set the test environment. This is what a basic testing process looks like:

Step 1: Assessing the development plan.
Step 2: Developing the test plan.
Step 3: Testing software requirements.
Step 4: Testing software design.
Step 5: Testing build phase.
Step 6: Recording results.
Step 7: Acceptance testing.
Step 8: Test Reporting.
Step 9: Installing software and maintenance.
Step 10: Evaluating test effectiveness.

How do you manage the test process? That’s where a test environment comes into play. A test environment can offer accurate feedback about the behavior and quality of the application under test. Now let’s try to understand what is test environment elements.

Elements of Test Environment

An environment that’s conducive to testing is a key component to ensuring the quality of test case executions. A stable test environment allows for dependable and consistent performance from the application under test and the testers themselves, as well as guaranteeing that all testers will work with a standard set of predetermined variables when conducting their tests. To achieve this type of test environment, several important elements need to exist in the test environment:

Let’s delve deeper into what is test environment elements. Various elements can be listed, and the elements are as follows.

*Database *— The database is among the most important software application parts. It could be a client-server, mobile, desktop, or web application; you would need a database at every part of the backend. One of the core elements of software testing is the data you use to test a particular software.
Automation testers — Automation test engineers are developers working on the programming, designing, testing, and simulation of any existing or new software.
Manual testers — A manual software tester would check for the new application quality without automation testing tools or scripting processes.
Network Protocols — These are the network configurations required by the software. Network throttling can help you test how your website performs at different speeds. The network configurations need to be set up according to the requirements of the applications as some of the applications can be tested on wireless networks, local area networks (LAN), and some may need private networks for testing.
The Operating system and Testing server — An operating system (OS) is nothing but a program that you load into the computer through a boot program. It would manage every application program on your computer.

What is Staging Environment?

A staging environment is nearly a practical copy of a production environment for software testing. All the code is present on the server itself of the local machine. When we have to do major version updates, it can be on the staging environment, where we can also fix the issues that come up.
Staging environments are used before the actual deployment of the software in the Production environment so that the final tests can be done like code testing, builds, and updates to ensure the quality of the software application.

It’s a known fact that just because your web application has passed the staging environment successfully, it might or might not pass the production environment, especially during cross browser testing, where you render your web application across different browsers, OS, and devices. You would never know what bugs your customers would face until you enter the production stage.

Every agile tester would come across a new testing requirement on a daily, weekly, or bi-monthly basis. When you focus on the test environment in the production stage, who would take care of the staging, the previous stage of the production stage, in case of any code changes? You need to focus on testing in both the staging and the production environment, which is an exhausting phase if done manually. In such cases, it’s widely believed that Selenium automation can help you during testing in production phase.

Make sure you subscribe to our LambdaTest YouTube channel to learn more about cross browser compatibility, automated browser testing, and more.

Difference between Staging and Production Environment?

The difference, in simple words, means staging is the pre-production resembling a production environment exactly. What do we need to know further? Let’s take a look:

STAGING ENVIRONMENT	PRODUCT ENVIRONMENT
A Staging Environment is a practical copy of a production environment meant for software testing.	A Production Environment is an environment where software is available on the production server.
The focus is to test the software or application before the final deployment.	In this environment, the final deployment is done.
Major version updates can be done in the staging environment.	You cannot perform major version updates in the staging environment. The production environment is where users access the final application after all the updates and testing.
It is a place where final code changes are tested and polished.	You have permission to make certain changes to the configuration on a direct basis to production, but code changes aren’t possible on a direct basis.

What is Test Bed?

A test bed is a test environment set up to test data without affecting the live production servers. A test bed is not only used by a tester but is also used by developers for the testing of different parts of an application without affecting the live production of the application.

Test beds are used to test rocket engines and in aircraft development for testing purposes. Physical facilitators are needed, and the software configuration binds up together and is treated as a test bed.

Difference between the Test Environment and Test Bed

The terms test environment and test bed are often confused as the same, but these terms do not refer to the same thing. It is important to understand their differences.

Test Environment: It is an environment that allows you to run the test cases according to the requirement of the user. It integrates the hardware (RAM, processor speed, and network configurations). Simply put, the test environment includes hardware elements and the software environment in which the tests are performed.

Test Bed: It is a configuration for execution or performance, specially designed for testing. Test bed contains test data used to verify the features and functionalities of other software/applications.

Importance of Test Environment

It’s vital to have a test environment since you can easily avoid negative test environment impacts, production stage downtime, and so on. Let’s see why we need to involve it:

A test environment gives precise feedback about the features and functionalities of the application, or we can say, a testing environment provides a necessary setup to run the test cases.
Testing environments are also used to test and identify the application for bugs and find a possible fix for the same for the smooth functioning of the application for the user.
It also helps you validate an application’s behavior by providing a standardized environment, and the application/software is tested safely, which also gives the user the benefit of security.
Using test environments, we can search for vulnerabilities to launch a secure, tested application for the user.

Types of Test Environment

When it comes to testing, different types of environments simply help reduce software flaws and issues. Here is your answer to test environment types:

Integration Testing Environment.

In this environment, you need to integrate the software modules. You can then verify the integrated system behavior. Several integration tests are used to check whether the system behavior is as specific as the user’s requirements. When you use an integration testing environment, you can integrate one, two, or many modules of the application and verify the functionalities through functional testing and the correctness of the application.

The environment setup usually depends on the application type and components that need to be tested. It is done by ensuring the correct software version and hardware availability along with the right configuration. The integration testing environment should imitate the production scenarios closely and include the configuration and management of application servers, web hosts, databases, and all the configurations needed by the application/software.

Performance Testing Environment.

This environment tells us how well a system would perform based on its goals. The performance goals can be referred to as concurrency, throughput, stability, and response time. Performance testing is the ability by which a product’s quality or the ability to function in a required manner is tested.

The setup of a performance testing environment is quite a complex task as it requires very selective choice and infrastructure configuration. You need to run the performance testing on numerous environments with distinct configurations that vary by the number of CPU cores, size of RAM, concurrent users, and volume of the data.

After the setup is carefully done, you can document and publish the results and compare the performance goals of the software. Once the testing team performs the performance testing, the software team looks closely at the system’s behavior. Performance testing is usually time-consuming and expensive as software testing is performed on several environments according to the different configurations.

Therefore setting up a performance testing environment and running these tests for every change is not recommended and is not considered a fine choice. That is the main reason why software teams are focusing only on running these performance tests as per the requirement basis based on a month or a year or as per the important application changes.

Security Testing environment.

In this type of testing environment, the major point that is kept in mind is the security of the software. While using this testing environment, the security teams try to ensure that the software is free of security flaws or vulnerabilities in confidentiality, authentication, integrity, and authorization.

As we all know, security is one of the most important aspects for the customer as well as the provider, so for this type of testing, not only the internal members of the organization but also the members from external organizations(who specialize in security testing) are hired so that the identification of vulnerabilities can be made more accurately.

To set up a good security testing environment, you must keep some points in mind, such as having an isolated test environment, never leaving the system unattended, and not touching the production data. If the system is left unattended for some reason, it should be protected by passwords so that the software is not accessible to anyone.

Chaos Testing Environment.

In this type of testing environment, The main aim is to find a specific area that can cause the failure of the application/ software before it leads to any negative user experience.

In chaos engineering and testing, after identifying the specific area that tends to cause the failure, the testers try to fix it and serve a well-functioned application to the user.

Challenges in setting up Test Environment

Test environment management requires an integrated approach. It’s quite apparent that there are many challenges involved, but let’s pick up the most vital ones:

Planning and Utilization of resources
An effective planning for the utilization of resources is a must as it may impact the results and can lead to conflicts between the teams. Planning the software, hardware, or environmental testing requirements can be challenging.
External environment
There is a possibility that a test environment is dependent on external environments. In these situations, the testing team has to rely on the support team for various test assets such as software, hardware, and other issues.
Extensive setup
Sometimes, test setup can be too complicated and challenging for the team to work on the configuration or setup of the test environment. In such cases, you need to rely upon the team’s expertise and budget, which might be a challenge by itself.
Collaboration between teams on usage
If the testing environment is used by different teams (Development and Testing) simultaneously, then there is a possibility that the test results are incorrect or invalid.
Setting up complex tests
Some of the tests require extensive test environment configuration, which can be challenging for the test team. The team may need to consider the needed factors such as time and resources to conduct complex tests. If done manually, it will not yield effective results every time.
Setting up the in-house infrastructure
Setting up and maintaining an in-house infrastructure for testing takes immense time and typically has scalability issues. Also, you need to invest in in-house device labs, which is also not a viable solution. A significant crucial challenge here is to keep all of them up to date with market trends.

Using a test orchestration and execution platform like LambdaTest eliminates the requirement for in-house infrastructure. It provides a cloud-based, reliable infrastructure for 3000+ browser and OS combinations. All of your tests may be run in a secure cloud environment.

Best Practices for setting up Test Environment

When you delve deeper into what is test environment best practices, you need to remember a few of them without which a testing environment cannot function properly. Here is the needed list:

Hardware Requirements
It is a good practice to know if all the required hardware components are available and if all the necessary hardware installations are done and tested before setting up the testing environment.
Software Requirements
Knowing the software’s availability is a must; if the software is already available, it should be verified that it is compatible with the testing environment.
Data items
We should check the availability of standard test data and the creation of the test data. You also need to check whether it is available in production or needs to be created.
Tools
Tools are the most viable factor in a test environment. All the necessary tools should be available when setting up, like debugging, defect reporting and all the essential tools required at the setup time.
Process
A check is kept on all the development strategies and plans. This is done to ensure that the process is up to the mark and bugs are reported on time.

Conclusion

A test environment is a host/server that allows you to run the test cases according to the requirement of the user or software to be tested. It not only sets up the host but also integrates hardware, software, and network configurations. It is also important to provide bug-free functional applications to the user.

Hence, we can say that the Testing environment plays a crucial role in testing software/applications and is widely used by most testers and developers to provide a better and more satisfying service to the user.
