What is Regression Testing? According to Wikipedia, Regression testing is an important type of software testing that revolves around re-running functional and non-functional tests. These tests are conducted to ensure and check the previously developed and tested software still perform well even after a change is made in the software.  Primarily, it checks whether the previous functionality of an application is working as intended even with a new feature added. It checks for any new bug or error in the existing software and is a verification process that takes place in the software. Whenever the new software is released, there is an essential need to test the new functionality. There is a necessity to re-run the old tests to ensure that new software does not re-introduce any old defects or create new ones that might affect the existing functionality.  Though software regression testing seems to be a simple concept, it is quite challenging as it tests the funct...

Usually, in the waterfall approach, a subset of Functional test cases is picked and the regression test suite is created. This approach is not effective in an Agile environment. The functions of the application are developed in iterations. With each sprint, many changes would have taken place in a functional area until the final delivery. The functional test cases of a particular functional area in sprint 1, may require changes in sprint 2, because of adaptive and iterative nature of development. Best Methods for Regression testing in Agile i. Automated regression testing: Because of the repetitive nature of these regression instances, they are ideal for automation. A parallel automatic run of regression testing can save time and enhance quality. ii. Range of testing: The reach of testing during iteration regression testing can be different from the scope of testing during full-regression testing. In iteration regression testing, a smaller scope can b...
