Regression Testing: Strategy, Framework, and Best Practices

Regression testing involves testing the unchanged parts of an app again and again. It ensures that the previous functionality of an application is working as intended and the new feature that has been added doesn’t introduce any new bug or error. This is basically a process of verification.

Regression testing is started as soon as the programmer adds a new functionality to an application or fixes any bug. This is because of the dependency between the newly added and previous functionality. This testing/verification hold immense importance, especially when there are continuous changes or improvement in the application.

Regression Testing Strategy

The amount of regression testing required depends upon the newly added feature. If the feature is large, then there are more chances of the application getting affected. So, testing must be performed thoroughly considering all the test cases.

Depending upon the inputs gathered by the tester, regression testing can be automated using selenium so that the test cases can be easily executed in a new build. When the test scope is large then selective tests are executed to save cost and time. Regression testing is basically performed to:

These are performed at various stages continuously throughout the software testing lifecycle. The best way is to perform regression testing after the sanity or smoke testing. An effective test plan must be created to outline the regression testing strategy and exit criteria. Performance testing can also be done to ensure optimum system performance.
