What is the difference between functional testing and regression testing in automation testing?

Functional Testing vs Regression Testing in Automation Testing:

Functional Testing: Functional testing in automation testing involves validating the functionality of the application by testing each function or feature to ensure that it works as expected. It focuses on the business requirements and user specifications to ensure that the software functions correctly.

Regression Testing: Regression testing in automation testing involves retesting the already tested functionalities to ensure that new changes or modifications do not affect the existing functionalities of the software. It helps in identifying any unintended side effects of the new changes and ensures that the software remains stable and functional.

While functional testing validates the intended behavior of the software, regression testing ensures that the software remains stable and reliable even after multiple changes and updates. Both types of testing are essential in automation testing to ensure the quality and reliability of the software product.

Overall, functional testing focuses on the individual functions of the software, while regression testing ensures the overall integrity of the software after modifications.

By understanding the differences between functional testing and regression testing in automation testing, testers can effectively plan and execute their testing strategies to deliver high-quality software products.
