  1. REGRESSION TESTING is a type of software testing that intends to ensure that changes (enhancements or defect fixes) to the software have not adversely affected it.[1]
  2. During regression testing, new test cases are not created but previously created test cases are re-executed.[1]
  3. Regression Testing can be done using both Black Box or White Box Testing methods.[1]
  4. In this post, we will see what is regression testing and when and how we do regression testing.[2]
  5. Regression testing gives confidence to the developers that there is no broken functionality after modifying the production code.[2]
  6. Interviewers may ask you why do you do regression testing.[2]
  7. We do software regression testing whenever the production code is modified.[2]
  8. Regression testing is the process of testing changes to software to ensure older programming still works with new changes.[3]
  9. Regression testing should be done whenever a new update is introduced into the software.[3]
  10. CI in combination with regression testing is considered a good software development practice, because it ensures that recent changes have not negatively impacted the software’s functionality.[4]
  11. Regression testing is intent upon mitigating risk by identifying coding deficiencies.[5]
  12. Regression testing retests the unrevised portions of an application to ensure they have not been negatively impacted by revisions, upgrades, or updates.[5]
  13. Regression testing should exist in every test plan and project estimation.[5]
  14. Regression testing can be a quality measure of whether new code complies or interferes with the functionality of the existing code with which it interacts.[5]
  15. Comprehensive orchestration APIs Remotely execute feature testing, regression testing, and integration testing scenarios with the platform’s API capabilities.[6]
  16. Reuse scripts Leverage the same scripts across all phases of feature and regression testing and ongoing management.[6]
  17. Regression testing is mostly automated, as it contains many tests that repeat during every testing session.[7]
  18. The aim of regression testing is to make sure that fixes, additions or improvements of the code haven’t caused new errors, and the reported errors do not appear any more.[7]
  19. The concept of application regression testing seems difficult for some people to understand, similarly to automation testing.[8]
  20. In this detailed guide, we will provide the exact regression testing definition.[8]
  21. For this reason, we’ll focus more on automated regression testing and regression automation.[8]
  22. This method focuses on selecting a number of tests instead of full regression testing.[8]
  23. In my last post, Why regression tests are so important, I explained what regression testing is and why you should implement sets of tests for all your development projects.[9]
  24. Instead of using manual testing, if you invest in automated regression testing, these numbers can be drastically reduced.[9]
  25. At first, we were performing the regression testing manually.[9]
  26. I would say that, on average, we spent eight hours per feature just on manual regression testing.[9]
  27. Regression testing is a specific form of testing that verifies whether a given piece of software suffered regressions after undergoing changes.[10]
  28. In today’s post, we’ll define and explain what automated regression testing means.[10]
  29. We’ll start by explaining what a regression is, how costly they are for software teams, and why you should employ regression testing to avoid them.[10]
  30. The first step in order to understand “automated regression testing” is to get rid of the “automated” part, at least for now.[10]
  31. Regression testing ensures that the changes have not introduced new bugs in the existing features which were working fine before.[11]
  32. Regression testing is also required in cases where the underlying technology is changed or upgraded due to old libraries are deprecated.[11]
  33. When a developer does code optimization or performance fixes then also testers perform regression testing.[11]

  41. Regression testing, or software testing performed after editing the software, is vital to maintaining functionality and optimum user experiences.[14]
  42. Regression testing should be performed any time a change is made to software (like a bug fix) to ensure that no other parts of the software have “regressed” from their previous functionality.[14]
  43. Each one has its pros and cons, and will require your software testing engineers to consider the goals of their regression testing strategy carefully.[14]
  44. Whatever approach you need, regression testing is a basic necessity of software quality assurance.[14]
