How To Optimize Regression Test Suite Effectively

Hi guys, I read a article about Optimize Regression Tests and for this reason I will summarize with my words what you can do more effectively with Regression Tests. According to different surveys, more than 70% of software work relates to application maintenance and improvement. This means that you will have a lot of work updating your regression test code and also keeping focus on the newer application functionality on the same time.

  • RTS – Regression Test Selection is one of the most popular methods for test case suite optimization. Divide the test suite into reusable test cases, retestable test cases and obsolete test cases. Apart from all these, it also creates new test cases that test the program for areas not covered in current test cases.
  • TRACK MECHANISM – The effectiveness of the regression test suite can be easily maintained by monitoring the changes to the test suite. A clearly outlined process will ensure that only tests that are useful to the entire testing strategy get added to the test suite, which ensures the efficiency and usability of the test harness at a high level.
  • PERIODIC CLEANUP – Considering periodic cleanup of old tests, all the existing tests in the test suite need to be analyzed for their effectiveness in a specific scenario. In such cases, the relevant regression test suites should also be eased out. It will ensure robustness of the regression test suite for a long period of time. You can also measure the effectiveness of regression test suites on a release-to-release basis. It will allow you to know the root cause for reduction in the effectiveness of the test harness if any, and enable you to take appropriate action on the same.
  • METRICS ANALYSIS – Collection of some metrics and their analysis could also be useful when it comes to the effectiveness of the regression test suite. You can consider different metrics such as percentage of defects found by the regression tests suite, their importance, etc.

You can consider optimization of tests when the tests get lengthy or huge, evaluate different regression test selection strategies and plan and explore changes in the regression test suite framework in order to maintain the effectiveness of the regression test suite.
