Grafana k6 and ASP.NET Core: A Practical Guide to Load & Stress Testing

Andy — Mon, 07 Aug 2023 20:59:14 +0000

Performance testing is a critical aspect of the development process, it helps ensure that our applications can handle varying levels of traffic and deliver a smooth user experience under heavy loads.

In this article, we will explore how to perform load and stress testing on ASP.NET Core 6.0 applications using Grafana k6, an open-source performance testing tool.

Understanding Load and Stress Testing

Load and stress testing are both types of performance testing, but they focus on evaluating the performance of a system under different levels of load and stress conditions. Let’s understand each of them.

Load Testing

Load testing involves assessing the performance of a system under expected and anticipated user loads. The main goal is to determine how well the system performs when multiple users access it simultaneously.

Key aspects

Scenarios: Test scenarios are designed to simulate real-world user behavior and usage patterns, including different types of user actions (e.g., browsing, searching, purchasing).
Load Levels: Gradually increase the number of virtual users (simulated users) to apply load on the system and observe how it responds. The load can be constant or vary over time (ramp-up or ramp-down scenarios).
Metrics: Common metrics in load testing include response time, throughput (transactions per second), error rates, and resource utilization (CPU, memory, etc.).
Objective: The primary objective is to ensure that the system meets performance requirements, maintains acceptable response times, and handles the expected number of users without crashing or degrading significantly.

Stress Testing

Stress testing, on the other hand, assesses the system’s behavior under extreme conditions beyond its normal operating capacity. The goal is to identify the system’s breaking point, where it starts to exhibit performance degradation or fails altogether.

Key aspects

High Load Levels: Apply a load that exceeds the system’s designed capacity, testing its resilience and ability to recover from such conditions.
Breaking Point: Aims to find the point at which the system starts to exhibit issues, such as increased response times, errors, or crashes.
Recovery Testing: After reaching the breaking point, stress tests may evaluate how well the system recovers once the load is reduced to normal levels.
Objective: The primary objective is to identify the system’s weaknesses, bottlenecks, and failure points, allowing developers and administrators to make necessary improvements and enhance the system’s robustness.

Why Grafana k6?

k6 is a powerful and user-friendly load-testing tool that has gained significant popularity in the developer community. It offers a simple yet expressive JavaScript scripting language, making it easy to write and maintain test scripts. With its support for modern protocols and ability to scale to thousands of virtual users, k6 is an excellent choice for load and stress testing in .NET applications.

Setting Up the Environment

Let's install Grafana k6 by following the official installation guide.

Writing Load Test Scripts

Using k6, we can create test scripts that simulate user behavior and generate realistic loads on our application. It allows us to define scenarios, set up HTTP requests, and perform assertions to validate the responses.

Let's create a JS file called load_test.js:



import http from 'k6/http';
import { check, sleep } from 'k6';

export let options = {
    stages: [
        { duration: '1m', target: 100 }, // Ramp-up to 100 virtual users over 1 minute
        { duration: '3m', target: 100 }, // Stay at 100 virtual users for 3 minutes
        { duration: '1m', target: 0 },   // Ramp-down to 0 virtual users over 1 minute
    ],
    thresholds: {
        http_req_duration: ['p(95)<300'], // 95% of requests must complete within 300ms
    },
};

export default function () {

    var response = http.get('https://localhost:7071/api/books'); // HTTP Get all books

    check(response, {
        'is status 200': (x) => x.status === 200 // An assertion
    });

    sleep(1); // Wait for 1 second between each request
}

For more info about stages and configuration

Writing Stress Test Scripts

Creates a JS file called stress_test.js:



import http from 'k6/http';
import { check, sleep } from 'k6';

export let options = {
    stages: [
        { duration: '5s', target: 5 },    // Stage 1(5 seconds): Ramp - up to 5 virtual users over 5 seconds.
        { duration: '30s', target: 5 },   // Stage 2 (30 seconds): Stay at 5 virtual users for 30 seconds.
        { duration: '5s', target: 50 },   // Stage 3 (5 seconds): Ramp-up to 50 virtual users over 5 seconds.
        { duration: '30s', target: 50 },  // Stage 4 (30 seconds): Stay at 50 virtual users for 30 seconds.
        { duration: '5s', target: 100 },  // Stage 5 (5 seconds): Ramp-up to 100 virtual users over 5 seconds.
        { duration: '30s', target: 100 }, // Stage 6 (30 seconds): Stay at 100 virtual users for 30 seconds.
        { duration: '5s', target: 300 },  // Stage 7 (5 seconds): Ramp-up to 300 virtual users over 5 seconds.
        { duration: '30s', target: 300 }, // Stage 8 (30 seconds): Stay at 300 virtual users for 30 seconds.
        { duration: '5s', target: 0 },    // Stage 9 (5 seconds): Ramp-down to 0 virtual users over 5 seconds.
    ],
    thresholds: {
        http_req_duration: ['p(95)<1000'], // 95% of requests must complete within 1000ms
        http_req_failed: ['rate<0.1'],     // Request failure rate should be less than 0.1%
    },
};

export default function () {
    var response = http.get('https://localhost:7071/api/books'); // HTTP Get all books

    check(response, {
        'is status 200': (x) => x.status === 200 // An assertion
    });

    sleep(0.1); // Wait for 0.1 second between each request (adjust as needed for higher stress)
}

ASP.NET Core API folder structure

How To Run The Tests

The first thing we need to do is to start our API, let’s run dotnet run -c release

Let’s proceed with the test. To begin, open a new console window and navigate to the API folder. Next, execute the following k6 command in the console



k6 run load_test.js

During the test execution, k6 will collect various performance metrics, including response times, throughput, and error rates. These metrics will help us assess the application’s behavior under load and identify any performance bottlenecks.

The process above it is only for the load tests, If you want to run the stress tests, just run k6 run stress_test.js

Analyzing Test Results

After the load and stress tests are complete, it’s time to analyze the results. Grafana k6 provides detailed reports and visualizations that help us understand the application’s performance characteristics. We can inspect metrics like response time distributions, error rates, and trends to pinpoint areas that need improvement.

http_req_duration, the end-to-end time of all requests (that is, the total latency)

http_req_failed, the total number of failed requests

iterations, the total number of iterations

Based on the insights gained from the test results, We can fine-tune our application, optimize its performance, and make it more resilient to handle higher user loads.

Final Thoughts

Grafana k6 is a powerful tool that helps us to ensure our applications can handle the expected user loads without compromising performance. We can simulate realistic scenarios, analyze performance metrics, and identify and address potential issues before they impact the final users.

ASP.NET Core Middleware: Working with Global Exception Handling

Andy — Mon, 31 Jul 2023 22:19:59 +0000

Exception handling is an important aspect of any robust web application. In ASP.NET Core, the process of handling exceptions has become even more streamlined with the use of custom middleware. In this article, we will walk through the steps of how to implement global exception handling in ASP.NET Core 6.

Exception Handling with Try-Catch Block

Here is a very basic code snippet to demonstrate the try-catch exception handling, and it should work effectively. Nevertheless, there are a few drawbacks to this approach when working with large applications.



[ApiController]
[Route("api/books")]
public class BookController : ControllerBase
{
    private readonly IMediator _mediator;
    private readonly ILogger<BookController> _logger;

    public BookController(IMediator mediator, ILogger<BookController> logger)
    {
        _mediator = mediator;
        _logger = logger;
    }

    [HttpPost]        
    [ProducesResponseType(StatusCodes.Status201Created)]
    [ProducesResponseType(StatusCodes.Status400BadRequest)]
    public async Task<IActionResult> AddBook(AddBookCommand command)
    {
        try
        {
            await _mediator.Send(command);
            return StatusCode(StatusCodes.Status201Created);
        }
        catch (Exception ex)
        {
            _logger.LogError(ex.Message);
            return StatusCode(StatusCodes.Status400BadRequest); 
        }
    }
}

Let’s consider a scenario where we have a substantial number of controllers in our project, each containing multiple actions. To handle exceptions effectively, we would be required to include a try-catch block in every action within each controller. In certain cases, we might also need to add try-catch blocks to our business logic, services, application layer, and so on. Consequently, our codebase would quickly accumulate an overwhelming number of lines, impacting its cleanliness and overall readability.

Fortunately, there is a more efficient approach we can implement to address the issue above. Custom Middleware.

What is Middleware?

Middleware is a fundamental concept that plays a crucial role in the request processing pipeline. It acts as a bridge between the incoming HTTP request and the application’s response. In simple terms, middleware can be thought of as a series of components that process requests and responses as they flow through the system.

When a request is received by an ASP.NET Core application, it passes through a chain of middleware components, each responsible for handling specific tasks. These tasks can include logging, authentication, routing, caching, and more. Each middleware can either terminate the request-response cycle or pass it along to the next middleware in the pipeline.

Exception Handling with Custom Middleware

Let’s create a record for the exception response since record types are highly suitable for data transfer objects (DTOs).



public record ExceptionResponse(HttpStatusCode StatusCode, string Description);

Here is our implementation for the global exception-handling middleware. As a best practice, we should organize this class within a folder named “Middleware.”



public class ExceptionHandlingMiddleware
{
    private readonly RequestDelegate _next;
    private readonly ILogger<ExceptionHandlingMiddleware> _logger;

    public ExceptionHandlingMiddleware(RequestDelegate next, ILogger<ExceptionHandlingMiddleware> logger)
    {
        _next = next;
        _logger = logger;
    }

    public async Task InvokeAsync(HttpContext context)
    {
        try
        {
            await _next(context);
        }
        catch (Exception ex)
        {
            await HandleExceptionAsync(context, ex);
        }
    }

    private async Task HandleExceptionAsync(HttpContext context, Exception exception)
    {
        _logger.LogError(exception, "An unexpected error occurred.");

        //More log stuff        

        ExceptionResponse response = exception switch
        {
            ApplicationException _ => new ExceptionResponse(HttpStatusCode.BadRequest, "Application exception occurred."),
            KeyNotFoundException _ => new ExceptionResponse(HttpStatusCode.NotFound, "The request key not found."),
            UnauthorizedAccessException _ => new ExceptionResponse(HttpStatusCode.Unauthorized, "Unauthorized."),
            _ => new ExceptionResponse(HttpStatusCode.InternalServerError, "Internal server error. Please retry later.")
        };

        context.Response.ContentType = "application/json";
        context.Response.StatusCode = (int)response.StatusCode;
        await context.Response.WriteAsJsonAsync(response);
    }
}

A step-by-step explanation of how it works

The middleware takes two parameters in its constructor: RequestDelegate next and ILogger logger. The next parameter represents the next middleware in the pipeline and the logger is used to log any exceptions that occur.

The core logic of the middleware is in the InvokeAsync method, which is called when an HTTP request is received by the application.

The InvokeAsync method wraps the execution of the next middleware in a try-catch block. This allows it to catch any exceptions that occur during the execution of the downstream middleware.

If an exception is caught, the middleware calls the HandleExceptionAsync method, passing the HTTP context and the exception as an argument. This method logs the error and decides how to handle the exception and creates an appropriate ExceptionResponse object.

Once the ExceptionResponse is generated, the middleware sets the HTTP response’s content type to JSON and the status code based on the ExceptionResponse. Then, it writes the ExceptionResponse as JSON to the HTTP response, informing the client about the error that occurred.

Register ExceptionHandlingMiddleware

We need to be sure about registering the ExceptionHandlingMiddleware in the request processing pipeline by adding the following line to the program.cs file. Be mindful to place it before other middleware registrations, as the order of middleware matters.



// Global error handler
app.UseMiddleware<ExceptionHandlingMiddleware>();

// Other middleware registrations..

Testing the API using Swagger



[ApiController]
[Route("api/books")]
public class BookController : ControllerBase
{
    private readonly IMediator _mediator;
    private readonly ILogger<BookController> _logger;

    public BookController(IMediator mediator, ILogger<BookController> logger)
    {
        _mediator = mediator;
        _logger = logger;
    }

    [HttpPost]        
    [ProducesResponseType(StatusCodes.Status201Created)]
    [ProducesResponseType(StatusCodes.Status400BadRequest)]
    public async Task<IActionResult> AddBook(AddBookCommand command)
    {
        //...
        //Throw exception just for testing purpose
        throw new Exception("Something went wrong...");

        await _mediator.Send(command);

        return StatusCode(StatusCodes.Status201Created);
    }

    [HttpGet]
    [ProducesResponseType(StatusCodes.Status200OK, Type = typeof(List<Book>))]
    public async Task<IActionResult> GetAllBooks()
    {            
        var books = await _mediator.Send(new GetAllBooksQuery());

        return Ok(books);
    }
}

Our middleware successfully intercepted an unhandled exception that arose during the processing of an HTTP post request.

Here we can enhance our application’s efficiency by saving pertinent logs, preparing a comprehensive response object, and promptly returning it to the client.

Final Thoughts

Exception handling middleware is a powerful tool in ASP.NET Core that helps in centralizing the handling of unhandled exceptions (Avoiding try-catch blocks everywhere) and providing consistent error responses to the clients.

Happy coding :)

10 Bad Practices to Avoid in ASP.NET Core API Controllers

Andy — Sat, 15 Jul 2023 13:51:05 +0000

When developing controllers in ASP.NET Core, there are certain practices that should be avoided to ensure maintainability, performance, and adherence to best practices. Here are 10 things we should avoid in our controllers.

1. Tight coupling

Avoid tightly coupling in controllers with specific dependencies or frameworks. Instead, use dependency injection to inject dependencies into controllers. This promotes loose coupling and makes the code more testable and maintainable.

// Avoid:
[ApiController]
[Route("[controller]")]
public class ProductController : ControllerBase
{
    ProductService productService = new ProductService();
    // ...
}


// Prefer:
[ApiController]
[Route("[controller]")]
public class ProductController : ControllerBase
{
    private readonly ILogger<ProductController> _logger;
    private readonly IProductService _productService;

    public ProductController(IProductService productService, ILogger<ProductController> logger)
    {
        _logger = logger;
        _productService = productService;
    }
    // ...
}

Learn more about dependency injection

2. Mixing concerns

Controllers should focus on handling HTTP requests and generating responses. Avoid mixing concerns such as data access, authentication, or authorization directly in the controller. Delegate these responsibilities to separate classes or middleware.

// Avoid:
[HttpPost]
public async Task<IActionResult> CreateProduct(ProductDto productDto)
{
    // Authentication and authorization logic here
    // ...
    // Data access logic here
    // ...
    return Ok(StatusCodes.Status201Created);
}


// Prefer:
[HttpPost]
[Authorize]
public async Task<IActionResult> CreateProduct(ProductDto productDto)
{
    await _productService.CreateAsync(productDto);

    return Ok(StatusCodes.Status201Created);
}

3. Lack of exception handling

Controllers should handle exceptions gracefully and return appropriate error responses. Avoid letting exceptions propagate to the client without proper handling. Implement global exception-handling mechanisms, such as exception filters or middleware, to centralize error handling.

// Avoid: (Inconsistent error handling or try catch everywhere)
[HttpPost]
public async Task<IActionResult> CreateProduct(ProductDto productDto)
{
    try
    {
        await _productService.CreateAsync(productDto);

        return Ok(StatusCodes.Status201Created);
    }
    catch (ProductValidationException ex)
    {
        return BadRequest(ex.Message);
    }
    catch (Exception ex)
    {
        _logger.LogError(ex, "An error occurred while creating the product.");
        return StatusCode(StatusCodes.Status500InternalServerError);
    }
}


// Prefer: Exception filters or Middleware
[HttpPost]
public async Task<IActionResult> CreateProduct(ProductDto productDto)
{
    await _productService.CreateAsync(productDto);

    return Ok(StatusCodes.Status201Created);
}

E.g of a global exception middleware

public class ExceptionMiddleware
{
    private readonly RequestDelegate _next;

    public ExceptionMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task InvokeAsync(HttpContext context)
    {
        try
        {
            await _next(context);
        }
        catch (Exception ex)
        {
            // Log the error
            // ...

            await HandleExceptionAsync(context, ex);
        }
    }

    private Task HandleExceptionAsync(HttpContext context, Exception exception)
    {
        context.Response.ContentType = "application/json";
        context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;

        var response = new
        {
            StatusCode = context.Response.StatusCode,
            Message = "Internal Server Error"
        };

        return context.Response.WriteAsync(JsonConvert.SerializeObject(response));
    }
}

With this exception middleware, any unhandled exceptions that occur during the processing of an HTTP request will be caught, and a JSON response with a generic error message and the status code 500 (Internal Server Error) will be returned to the client.

We can customize the HandleExceptionAsync method to include more detailed error information or modify the response structure as per our requirements.

To use this middleware in our ASP.NET Core Web API application, we can add the following code to our Startup.cs file or Program.cs .net 6.

app.UseMiddleware<ExceptionMiddleware>();

4. Long-running operations

Avoid performing long-running operations synchronously in controllers. Offload such tasks to background workers or use asynchronous programming.

// Avoid:
[HttpGet]
public IActionResult GenerateReport()
{
    // Long-running operation
    // ...
    return Ok(report);
}


// Prefer:
[HttpGet]
public async Task<IActionResult> GenerateReport()
{
    // Offload the long-running operation to a background worker
    await _reportGenerationService.GenerateAsync();
    return Ok();
}

5. Lack of validation

Input validation is crucial to ensure the integrity and security of the application. Avoid neglecting input validation in your controllers. Leverage model validation attributes, such as [Required], [MaxLength], and custom validation logic to validate incoming data.

// Avoid:
[HttpPost]
public async Task<IActionResult> CreateProduct(ProductDto productDto)
{
    // No validation
    await _productService.CreateAsync(productDto);
    return Ok(StatusCodes.Status201Created);
}


// Prefer:
[HttpPost]
public async Task<IActionResult> CreateProduct([FromBody] ProductDto productDto)
{
    if (!ModelState.IsValid)
    {
        return StatusCode(StatusCodes.Status400BadRequest, ModelState);                
    }

    await _productService.CreateAsync(productDto);
    return Ok(StatusCodes.Status201Created);
}

6. Direct database access

Avoid directly accessing the database from the controllers. Instead, use an abstraction layer, such as repositories or data access services, to decouple the controllers from specific data access technologies. This improves testability and maintainability.

// Avoid:
[HttpGet]
public IActionResult GetProduct(int productId)
{
    var product = dbContext.Products.Find(productId);
    return Ok(product);
}


// Prefer:
[HttpGet]
public async Task<IActionResult> GetProduct(int productId)
{
    var product = await _productService.GetByIdAsync(productId);
    return Ok(product);
}

Learn more about Repository Pattern or Data Layer

7. Lack of caching

Avoid not utilizing caching mechanisms when appropriate. Leverage caching to improve performance and reduce load on the server.

// Avoid:
[HttpGet]
public async Task<IActionResult> GetProducts()
{
    var products = await _productService.GetAllAsync();
    return Ok(products);
}


// Prefer:
[HttpGet]
[ResponseCache(Duration = 60)] // Cache the response for 60 seconds
public async Task<IActionResult> GetProducts()
{
    var products = await _productService.GetAllAsync();
    return Ok(products);
}

Learn more about Caching | Response caching

8. Lack of authentication and authorization

Avoid not implementing authentication and authorization for sensitive operations. Secure the controllers accordingly.

// Avoid:
[HttpPost]
public async Task<IActionResult> DeleteProduct(int productId)
{
    // No authentication or authorization
    await _productService.DeleteAsync(productId);
    return StatusCode(StatusCodes.Status200OK);
}


// Prefer:
[HttpPost]
[Authorize(Roles = "Admin")]
public async Task<IActionResult> DeleteProduct(int productId)
{
    await _productService.DeleteAsync(productId);
    return StatusCode(StatusCodes.Status200OK);
}

Learn more about Authentication and Authorization

9. Excessive logic

Controllers should primarily be responsible for handling incoming requests and returning responses. They should not contain complex business logic. Instead, delegate the business logic to dedicated service classes or other components.

// Avoid:
[HttpGet]
public async Task<IActionResult> GetProducts()
{
    // Complex business logic here
    // ...
    // ...
    // ...

    return Ok(products);
}


// Prefer:
[HttpGet]
public async Task<IActionResult> GetProducts()
{
    var products = await _productService.GetAllAsync();
    return Ok(products);
}

10. Ignoring HTTP verbs and RESTful principles

Controllers in ASP.NET Core should adhere to the principles of RESTful architecture. Avoid using improper HTTP verbs or actions that don’t align with RESTful conventions. Use appropriate HTTP verbs (GET, POST, PUT, DELETE, etc.) to perform corresponding operations on resources.

// Avoid:
public IActionResult DeleteProduct(int id)
{
    // ...
}


// Prefer:
[HttpDelete("/api/products/{id}")]
[ProducesResponseType(StatusCodes.Status200OK)]
[Authorize]
public IActionResult DeleteProduct(int id)
{
    // ...
}

Writing Clear and Concise Code: 11 Guidelines for C# Developers

Andy — Wed, 28 Jun 2023 21:33:46 +0000

Writing clear and concise code is a fundamental skill that we developers should strive to master. Clean code is not only easier to read and understand but also promotes maintainability, collaboration, and efficient debugging.

I could list all of the qualities that I notice in clean code, but there is one overarching quality that leads to all of them. Clean code always looks like it was written by someone who cares. There is nothing obvious that you can do to make it better. All of those things were thought about by the code’s author, and if you try to imagine improvements, you’re led back to where you are, sitting in appreciation of the code someone left for you — code left by someone who cares deeply about the craft. Michael Feathers, author of Working Effectively with Legacy Code

Let’s look at some examples:

Overcomplicating Code

Bad way

public string GetFormattedName(string firstName, string middleName)
{
   string formattedName = string.Empty;

   if (!string.IsNullOrEmpty(firstName))
   {
      formattedName += firstName.Trim();
   }

   if (!string.IsNullOrEmpty(middleName))
   {
      if (!string.IsNullOrEmpty(formattedName))
      {
         formattedName += " ";
      }

      formattedName += middleName.Trim();
   }

   return formattedName;
}

Good way

public string GetFormattedName(string firstName, string middleName)
 => string.Join(" ", firstName?.Trim(), middleName?.Trim()).Trim();

In the simplified code, the string.Join method is used to concatenate the names with spaces, and the ?. null-conditional operator is used to handle potential null values. The code is more concise, easier to read, and achieves the same functionality without unnecessary complexity.

Overcomplicating code can lead to increased cognitive load, reduced maintainability, and higher chances of introducing bugs. It’s important to strive for simplicity and readability in code whenever possible. Let's take a look at another example.

Bad way

bool isEven = (number % 2 == 0) ? true : false;

Good way

bool isEven = number % 2 == 0;

Loops Instead of LINQ

90% of cases loops can be substituted with a LINQ query. It might be my personal viewpoint, but I believe LINQ query is much more comprehensible than a significantly larger for-loop.

Bad way

public List<int> GetEvenNumbers(List<int> numbers)
{
   List<int> evenNumbers = new List<int>();

   foreach (int number in numbers)
   {
      if (number % 2 == 0)
      {
         evenNumbers.Add(number);
      }
   }

   return evenNumbers;
}

Good way

public List<int> GetEvenNumbers(List<int> numbers) 
 => numbers.Where(number => number % 2 == 0).ToList();

Complex IF Condition

A complex if condition refers to a conditional statement that involves multiple logical operations, conditions, or an expression that might be difficult to read and maintain.

Bad way

if (number % 2 == 0)
{
   // Do something
}

Better way

private bool IsEven(int number) => number % 2 == 0;

if (IsEven(number))
   {
     // Do something
   }
}

This practice helps in reducing code duplication, improving code organization, and enhancing code maintainability.

Deep Nesting

In the example below, the code is 3-level nested and this can make the code harder to understand and maintain. Deep nesting can also increase the risk of introducing logical errors and make code modifications more challenging.

Bad way

if (condition1)
{
    if (condition2)
    {
        if (condition3)
        {
            // Do something
        }
    }
}

Good way

if (condition1 && condition2 && condition3)
{
    // Do something
}

Just ensure that the conditions are logically correct and properly grouped. Also, it might be a perfect time to refactor and extract them into methods as we did in the previous example IsEven.

String Concatenation

The GenerateGreeting method concatenates multiple strings using the + operator. While this code may work correctly, it can become problematic when dealing with more complex scenarios or a large number of concatenated strings

Bad way

public string GenerateGreeting(string name)
{ 
   return "Hello, " + name + "! " + "How are you today?";
}

Good way

public string GenerateGreeting(string name)
{ 
   return $"Hello, {name}! How are you today?";
}

Magic Numbers

Avoid using magic numbers. Assign meaningful constants or enumerations to such values to improve code clarity and maintainability.

Bad way

if (status == 2)
{
    // Do something
}

Good way

const int InProgressStatus = 2;

if (status == InProgressStatus)
{
    // Do something
}

Long Methods

Break down long methods into smaller, focused methods. This improves code readability, reusability, and maintainability.

Bad way

public void ProcessData()
{
    // Several hundred lines of code
}

Good way

public void ProcessData()
{
    ValidateInput();
    CalculateValues();
    SaveData();
}

Poor Naming Conventions

Using meaningful and descriptive names for variables, methods, and classes improves code readability and helps others understand our code.

Bad way

var dt = DateTime.Now.ToString("YYYY/MM/DD");

Good way

var currentDate = DateTime.Now.ToString("YYYY/MM/DD");

Inconsistent Formatting

Consistent and properly indented code enhances readability and reduces confusion.

Bad way

public void PrintNumbers()
{
for (int i = 0;i < 10; i++)
{
Console.WriteLine(i);
}
}

Good way

public void PrintNumbers()
{
    for (int i = 0; i < 10; i++)
    {
        Console.WriteLine(i);
    }
}

Excessive Comments

Avoid commenting on obvious code. Comments should be used to explain complex logic or clarify code that may be unclear.

Bad way

// Increment counter by 1
counter++;

Good way

counter++;

File-Scoped Nested Namespaces

File-scoped namespaces were introduced in C# 10.0 and allow us to define namespaces directly at the file level without enclosing them in a traditional namespace block

// File-scoped nested namespace declaration
namespace MyApplication.Utilities
{
    public static class Helper
    {
    }
}

Better way

namespace MyApplication.Utilities;

public static class Helper
{
}

Final Thoughts

By avoiding these bad practices and adopting good coding practices, we can significantly improve the readability, maintainability, and overall quality of our C# code.

How To Generate Fake Data With Bogus in .NET 6

Andy — Wed, 21 Jun 2023 16:04:32 +0000

Bogus is a popular open-source library for generating fake data in .NET applications. It allows us to create realistic-looking, randomized test data for various purposes, such as unit testing, database seeding, or generating sample data for demonstrations.

In .NET 6, we can easily incorporate Bogus library into our projects by adding it as a NuGet package. Once installed, we can leverage its extensive set of data generation capabilities to create realistic and diverse fake data.

Key features and benefits

Data Population: Bogus provides methods for easily populating objects and collections with fake data. This is particularly useful for database seeding or creating large datasets for performance testing.
Realistic Data: The generated data from Bogus is designed to resemble real-world data. It follows patterns, distributions, and variations typically found in actual data, helping us create more accurate test scenarios and sample datasets.
Rich Data Generation: It provides a wide range of data generators that can create fake data for common types like names, addresses, phone numbers, email addresses, dates, numbers, and more. It also supports generating custom data types using fluent API extensions.
Localization Support: It supports generating data in multiple languages, making it suitable for internationalization testing or multi-lingual applications. It includes built-in localization for various countries and allows us to define our custom locales.
Customization Options: We can customize the generated data to match specific requirements. Bogus allows us to control the format, constraints, and patterns of the generated data, ensuring it aligns with our application’s needs.
Integration with Entity Framework Core: If you’re using Entity Framework Core in your .NET 6 project, Bogus includes built-in integration to help you generate fake data for your database entities and seed your database with realistic test data.

How to use

Install Nuget Package Bogus



Install-Package Bogus

Let’s use a User as an example



public class User
{
    public int Id { get; set; }
    public string? Name { get; set; }
    public string? LastName { get; set; }
    public string? Country { get; set; }
    public string? Phone { get; set; }
}

Next step we just need to configure how the data will be generated.

The first parameter of the RuleFor method is a lambda to pick the property on User that we want to fake. The second parameter is another lambda to pass in how to generate the property.



public class UserRepository
{
    public List<User> GetSampleData()
    {
        var userId = 1;

        var userFaker = new Faker<User>()
            .RuleFor(u => u.Id, _ => userId++)
            .RuleFor(u => u.Name, f => f.Name.FirstName())
            .RuleFor(u => u.LastName, f => f.Name.LastName())
            .RuleFor(u => u.Country, f => f.Address.Country())
            .RuleFor(u => u.Phone, f => f.Phone.PhoneNumberFormat());

        var users = userFaker.Generate(1000);

        return users;
    }
}

To use the Faker, we just need to call Generate method with how many users we want.

As we can see 1000 users were generated using realistic names. This is because Bogus contains a set of generalized rules for common data categories (i.e. Names, Addresses, Companies, People, Phone Numbers, etc.)

With Bogus, we can generate data in more than 45 languages.

We just need to pass the locale code inside the constructor.



var userFaker = new Faker<User>("es")

Happy Coding :)

Final Thoughts

Overall, Bogus is a powerful tool that simplifies the process of generating fake data in .NET 6 applications. It enables us to create diverse, realistic, and customizable test data, saving us time and effort in the development and testing process.

Step-by-Step Guide: Testing HTTP Endpoints in Visual Studio 2022 Using Endpoints Explorer

Andy — Tue, 13 Jun 2023 22:40:51 +0000

Visual Studio 2022 (v17.6) has introduced a new feature that simplifies the process of discovering and testing API endpoints. With this new feature, we can now effortlessly locate and test API endpoints within Visual Studio itself, streamlining our testing workflow.

The Visual Studio team has dedicated significant resources to enhance the experience of API development, testing, and debugging. Among the numerous recent additions, the Endpoints Explorer stands out as a noteworthy feature.

Endpoints Explorer

To use this feature go to View –> Other Windows –> Endpoint Explorer

It automatically identifies the endpoints within our project that utilize the [ApiController] attribute, providing us with a comprehensive overview of the project and its associated endpoints.

If we invoke Generate Request an HTTP file will be generated with the request for the /api/users

The following process has occurred:

An HTTP file was created and added to the project.
A variable was created to store the host address.
The request was added to the file.

Let's run our API and make some HTTP requests.

HTTP Get

After sending the request, we can instantly view the response on the right side, providing immediate visibility into the received data.

HTTP Post

Debugging

Highly intuitive for debugging!!! :)

Final Thoughts

The feature greatly simplifies the process of testing HTTP endpoints and verifying the response, eliminating the need for external tools such as Postman or Insomnia.

How To Use FluentValidation in ASP.NET Core (.NET 6)

Andy — Thu, 08 Jun 2023 22:01:46 +0000

FluentValidation is a popular validation library for .NET applications. It provides a fluent and expressive syntax for defining validation rules for our models. With FluentValidation, we can easily validate user input and ensure data integrity, reducing the chance of errors and improving the overall quality of our application.

The library supports a wide range of validation rules and features, including:

Customizable Validation Rules
Property-Level and Cross-Property Validation
Error Messages and Localization
Rule sets — group validation rules together
Asynchronous Validation
Custom Error Codes and Severity Level
Testing Support and more.

It integrates seamlessly with ASP.NET Core, making it a versatile choice for implementing robust and maintainable validation logic in our .NET projects.

How to Configure FluentValidation

Let’s follow the steps below in our ASP.NET Core Web API project:

1- Install the NuGet packages



Install-Package FluentValidation
Install-Package FluentValidation.DependencyInjectionExtensions

2-Register the Service

Once installed, we’ll need to modify our Startup class to include a call to AddFluentValidationAutoValidation()



var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();
builder.Services.AddFluentValidationAutoValidation();

This method must be called after AddMvc (or AddControllers/AddControllersWithViews). Make sure you add using FluentValidation.AspNetCore to your startup file so the appropriate extension methods are available.

3-Define the Model

The following example will make use of a User object.



public class User
{
    public string Name { get; set; }
    public int Age { get; set; }
}

4-Create a Validator Class

Let’s create a validator class that inherits from AbstractValidator, where T is our User class. Define the validation rules within the validator class.



using FluentValidation;

public class UserValidator : AbstractValidator<User>
{
    public UserValidator()
    {
        RuleFor(user => user.Name).NotEmpty().WithMessage("Name is required.");
        RuleFor(user => user.Age).InclusiveBetween(18, 99).WithMessage("Age must be between 18 and 99.");
    }
}

5-Register the Validator

If you’re using MVC, Web API, or Razor Pages you’ll need to register your validator with the Service Provider in the Startup class.



var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();
builder.Services.AddFluentValidationAutoValidation();
builder.Services.AddScoped<IValidator<User>, UserValidator>();

6-Usage

Unlike the manual validation example, we don’t have a reference to the validator directly. Instead, ASP.NET will handle invoking the validator and adding the error messages to ModelState before the controller action is invoked. Inside the action, we only need to check ModelState.IsValid



// Automatic validation
[HttpPost]
public IActionResult Create(User model)
{
     if (!ModelState.IsValid)
     {
        return StatusCode(StatusCodes.Status400BadRequest, ModelState);
     }

     // Continue with user creation process

     return StatusCode(StatusCodes.Status201Created, "User created successfully!");
}

When we make a POST request with the wrong name and age input, we then get returned the Error Validation Result.

In case you prefer to take a more explicit approach (manual validation), you have the option to specifically designate the class or model for which you want to create the validator. In this scenario, the Validate method would provide a ValidationResult object with two key attributes. The first is IsValid, a boolean indicating the success or failure of the validation process. The second attribute is Errors, which comprises a list of ValidationFailure objects containing detailed information about any encountered errors.

We can implement this as follows:



// Manual validation
[HttpPut]
public IActionResult Update(User user)
{
     var validationResult = _userValidator.Validate(user);

     if (!validationResult.IsValid)
     {
        return StatusCode(StatusCodes.Status400BadRequest, validationResult.Errors);
     }

     // Continue with user update process

     return StatusCode(StatusCodes.Status200OK, "User updated successfully!");
}

When we make a PUT request with an input error in the request, we then get returned the Error Validation Result.

Final Thoughts

FluentValidation offers a compelling alternative to Data Annotations for model validation. It empowers developers with enhanced control over validation rules, resulting in code that is more readable and easier to test. By implementing FluentValidation, we can achieve a clearer separation of concerns, ensuring that validation logic remains distinct and manageable.

3.What is the difference between ASP.NET Web Forms and ASP.NET MVC?

Answer: ASP.NET Web Forms uses a stateful programming model, while ASP.NET MVC uses a stateless model. MVC provides better control over HTML, allows more testable code, and supports cleaner separation of concerns.

4.How do you define a route in ASP.NET MVC?

Answer: Routes in ASP.NET MVC define the URL patterns and map them to controller actions. A route is defined in the RouteConfig class using the MapRoute method.

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

5.What is the Razor view engine in ASP.NET MVC?

Answer: Razor is a view engine used in ASP.NET MVC to render HTML views. It provides a compact syntax that combines HTML markup with server-side code.

<h1>Welcome, @Model.Name!</h1>

6.What is a ViewModel in ASP.NET MVC?

Answer: A ViewModel is a class that represents the data and behavior specific to a view. It is used to transfer data from the controller to the view and can contain additional properties or methods required for presentation logic.

7.Explain the concept of model binding in ASP.NET MVC.

Answer: Model binding automatically maps HTTP request data to action method parameters or properties of a model class. It simplifies the process of capturing user input and binding it to the corresponding model properties.

[HttpPost]
public ActionResult Create(Product product)
{
    // Code to save the product
    return RedirectToAction("Index");
}

8.How do you perform validation in ASP.NET MVC?

Answer: ASP.NET MVC provides both server-side and client-side validation. Server-side validation can be done using data annotations or custom validation logic.

public class Product
{
    [Required]
    public string Name { get; set; }

    [Range(1, 100)]
    public decimal Price { get; set; }
}

9.What is the TempData object in ASP.NET MVC?

Answer: TempData is a dictionary-like object used to store data temporarily between two consecutive requests. It is primarily used to transfer data from one action to another or from a controller to a view.

public ActionResult Create(Product product)
{
    // Code to save the product
    TempData["Message"] = "Product created successfully!";
    return RedirectToAction("Index");
}

10.Explain the concept of Areas in ASP.NET MVC.

Answer: Areas are used to organize large MVC applications into smaller functional sections. Each area can have its own controllers, views, and models. Areas help maintain a modular and structured application architecture.

11.What is the difference between ActionResult and ViewResult?

Answer: ActionResult is the base class for action results, while ViewResult represents a result that renders a view to the response. ViewResult derives from ActionResult and is commonly used to return a view from an action.

12.What is the difference between PartialView and View in ASP.NET MVC?

Answer: View renders a complete HTML page, including the layout and view content. PartialView renders a portion of the HTML page, typically used for rendering reusable

public ActionResult Index()
{
    // Full view
    return View();

    // Partial view
    return PartialView();
}

13.What are Action Filters in ASP.NET MVC?

Answer: Action Filters are attributes that can be applied to controllers or action methods to modify the behavior of the action execution. They can be used for logging, authorization, caching, and other cross-cutting concerns.

14.Explain the concept of Dependency Injection (DI) in ASP.NET MVC.

Answer: Dependency Injection is a design pattern that allows objects to define their dependencies through constructor parameters or properties. In ASP.NET MVC, DI frameworks like Unity or Ninject are commonly used to manage object dependencies.
