It's like having a robot handle the repetitive parts of software testing, freeing up your human testers to focus on more complex scenarios and edge cases. Test automation helps development teams release higher-quality software faster by quickly identifying bugs and other issues early in the development cycle.
Definition and Purpose
QA automation involves creating and running automated test scripts that check different aspects of your software, such as functionality, performance, and security. These scripts define specific actions the software should perform and the expected results. If the actual results differ from the expected results, the test fails, alerting the team to a potential problem. This automated approach speeds up the testing process and makes it much more efficient, especially for large projects or when you need to run tests repeatedly.
Manual Testing vs. Automation
Manual testing relies on human testers to perform tests step by step, interacting with the software as a user would. While essential for exploratory testing and usability evaluations, manual testing can be time-consuming and prone to human error, especially for repetitive tasks. Automated testing uses scripts and tools to execute tests automatically, making it faster and more reliable for repetitive tests like regression testing. The best approach often involves combining manual and automated testing to leverage the strengths of each.
