What is Automation Testing?

Automation testing is a powerful technique used in the world of software development to make sure that the software works perfectly and smoothly. Imagine having a group of special computer programs that can test other computer programs – just like little testers!

These testing programs, also known as "test scripts," are designed to mimic the actions of a human user. They can click buttons, fill in forms, enter data, and do all sorts of things that real users would do. The difference is that these test scripts can do it all much faster and more accurately than a human ever could.

The main goal of automation software testing is to find any mistakes or "bugs" in the software. If any bugs are discovered, developers can quickly fix them to ensure that the software is running smoothly and without any hiccups.

Automation testing is like having a team of reliable helpers who work tirelessly to ensure that the software is in tip-top shape. By automating the testing process, software development teams can save time, reduce human errors, and deliver high-quality products to their users.
