Level Up Your Automation: Essential Websites for Hands-On Testing Practice

Mastering test automation requires more than just understanding theory; it demands hands-on practice. Finding suitable, reliable “playgrounds” where you can experiment with different scenarios – from basic UI interactions to complex AJAX handling, modern frameworks, API calls, and mobile gestures – is crucial for skill development.

But where can you find these resources? Many live websites aren’t appropriate targets, and building complex test apps yourself takes time away from learning automation techniques. Fortunately, several excellent websites and applications are available, specifically designed or perfectly suited for automation practice.

Here’s a curated collection of valuable resources that can help you build a robust automation skill set, covering a wide spectrum of technologies and challenges.
