What is Regression Testing?

The Testing life cycle is not something new to people who have a fair understanding of the various tests being carried out on the software. Regression test, which is part of the release cycle, is so important that it needs to be considered in test estimation.

It’s possible that newer bugs are introduced when you fix a known /reported bug. Testers perform Functional tests to verify if the new changes work as expected. It’s also equally important to check that existing functionalities work as expected.

Regression testing is an essential part of software development and Test cycle, which enforces quality measure to check that new code complies with existing code and that unmodified code does not get affected.

Automating Regression tests provides you with the flexibility to – Run test cases after every change, include new test cases, no manual intervention or overhead in test case execution or unnecessary resource dependability. It is recommended to carry out regression test after a sanity/smoke testing or at the end of Functional testing, for Shorter releases. You may also choose to run automated regression test towards the end of each day to catch bugs early and fix them in the next build.

Regression testing suite /tool helps you to package and execute all the test cases automatically. Some of the third party/open-source regression testing tools available in the market are –

  • Selenium-Web browser Automation
  • UFT-Unified Functional Testing
  • Test Complete-Automated Software Testing Made Simple
  • Protractor – end to end testing for AngularJS
  • Tricentis Tosca Testsuite
  • Squish-Automated GUI Regression Testing Tool
  • While you evaluate multiple tools, it will be worthwhile to create a scorecard on various parameters such as – Ease of scripting, Integration, Usage, Reporting. Some of these parameters are listed below –

  • How easy it is to add /modify test cases, Ease of adoption
  • Does the tool support all development environment (like Java, .Net, Ruby, Python)
  • Do you need to test multiple operating systems (Windows, Andriod, iOS, etc.)
  • Skill set available in your organization
  • The quality of technical support provided
  • Along with the product pricing, consider Support fee, Training, Upgrade, etc.
