What I Learned in a Decade of Experience in Test Automation

Let’s start with the big question that many people ask: which programming language should you choose for automation?

Everyone seems to have a favorite. Whether it’s JavaScript, Python, Java, or C#, people often swear by the language that has worked best for them. But here’s the truth: all programming languages have the same foundational principles. They differ in syntax, libraries, and how they handle certain tasks, but the building blocks remain the same.

That said, some languages are undeniably better suited for certain tasks. Some execute faster, others are easier to set up, and some are more beginner-friendly. My advice? Pick one language and focus on mastering it. Don’t try to learn too many languages at once—it’s better to go deep than wide, especially early in your journey.

How Programming Languages Compare in Test Automation

The language you choose can impact the speed and ease of your test automation efforts. Here’s a simplified comparison of some popular languages for key testing criteria:

Don’t Chase Shiny Objects

One of my favorite quotes is:

“We are always chasing shiny objects.”

— Tim Corey

It’s tempting to switch to the latest language or framework whenever something doesn’t go as planned. But no language or tool is perfect. When you hit a roadblock—like a feature that isn’t supported or something that doesn’t work the way you expect—try to find a solution instead of jumping ship. The software industry thrives on problem-solving, and switching languages at every obstacle would make progress impossible.

Wrapping It Up

Test automation is about more than just tools and languages—it’s about solving problems. By mastering one language and learning the ins and outs of its frameworks, you’ll be equipped to handle most challenges that come your way. As you gain experience, you’ll be able to adopt new tools and languages with confidence, not because they’re trendy, but because they truly meet your needs.
