Explanation of the Difference Between Functional Testing and Regression Testing in Automation Testing

Functional testing in automation testing focuses on verifying that individual functions of the software application work as expected. It evaluates the application against the requirements provided and ensures that it meets the desired functionality.

On the other hand, regression testing in automation testing involves retesting the already tested functionalities to make sure that recent code changes have not adversely affected existing features. It ensures that new updates or modifications in the application do not introduce new bugs or issues.

In summary, functional testing checks the individual functions of the application, while regression testing ensures that the existing functionalities continue to work as expected after any changes. Both types of testing are crucial in automation testing to maintain the quality and stability of the software application.
