🔍 What is Automation Testing?
Automation Testing is the process of using software tools and scripts to automatically execute test cases on applications, compare actual outcomes with expected results, and report defects. It reduces manual effort, increases test coverage, and ensures consistent and repeatable testing across different environments.
Instead of testing everything by hand, automation helps you test faster, smarter, and more accurately — especially in agile and DevOps environments.
🚀 Why Learn Automation Testing?
In today’s fast-paced development world, manual testing alone can’t keep up with continuous integration, fast releases, and complex applications. That’s why automation testing has become an essential skill for testers, QA engineers, and even developers.
With automation testing, you can:
Run tests quickly across multiple browsers and devices
Catch bugs early with CI/CD integration
Save time and resources in regression testing
Improve software quality and team efficiency
