Web automation testing means using scripts to check if a website works correctly. Instead of testing manually, which takes time and is prone to mistakes, you write code to simulate user actions—like clicking buttons, filling forms, or checking page titles. This helps find problems faster and lets developers release code more often with more confidence.

It’s especially useful in large projects where testing everything manually isn’t realistic. Automated tests can run any time—before a release, during development, or overnight. Teams can find bugs earlier in the process.

Most automation tools work with common browsers like Chrome or Firefox. They interact with the page just like a user would. But unlike users, they never get tired or miss things.

Web automation is a big part of continuous integration and delivery (CI/CD). It ensures that small changes don’t break other parts of the site. If used well, it saves time, improves quality, and reduces stress.

So in short: write tests once, run them often, and catch issues early. That’s the point of automation.
