Automation Testing is a software testing technique that uses specialized tools and scripts to automatically execute test cases. This approach helps to verify that the software functions as intended without the need for manual intervention. By automating repetitive tasks, it increases efficiency and reduces the likelihood of human error. In Automation Testing, tests can be run multiple times with consistent results, making it easier to identify defects. It is particularly useful for regression testing, where previously tested features need to be re-evaluated after changes. Overall, it enhances the reliability and speed of the software development process.
