What is regression testing?

It is a testing method wherein unintended issues or defects that may have been introduced during software modifications or development are identified by the regression test method. The functionality of the upgrade is examined by the regression test method.

This testing method makes sure that the new updates or changes done to the code do not obstruct the existing functionalities of the application. The bugs that may have been present in the newly pushed code are identified. Any unexpected issues or behavior that may impact user experience are also detected by this testing method. This in turn ensures that the software is stable.

The need to automate regression testing:

There is a constant repetition that may be required in the regression test process. A fair amount of regression testing is included in every release cycle to make sure that new development does not break functionality or introduce bugs.

Various factors such as new browser versions, database updates, routine bug fixes and new features may be the cause of regression issues. When repeatable and stable regression cases are automated, the testers can in turn focus on testing different environments. This in turn helps in making sure that the speed and efficiency of the testing process is maintained accordingly.

Automated regression testing best practices:

1. Regression test cases need to be updated: There should be a regular update of regression test cases, which in turn helps in making sure that the test plan is aligned with the latest application version.

2. Successful test cases need to be re-run: Whenever there are software updates, all successful test cases need to be re-run, so that the app's functionality can be properly verified. The software's functionality can be altered by the updates that may have been made and also potential defects can be identified, once the tests are being re-run.

3. Tests need to be categorized: The task management process can be benefitted once the tests have been categorized. Once the category of a test is known, the sources of any failures being identified are simplified.
