Regression testing is a must-have testing activity. A quite common best practice is to build a regression test suite consisting of many related test cases for a particular feature. This test suite is scheduled to run automatically after a code update to check if that particular feature is affected by the update. The real question is not about how to build a regression test suite, but rather, on what criteria we should categorize our test cases.
Regression testing is a necessary process that grows over time, consuming larger amounts of testing capacity as applications scale in features. Katalon TrueTest™ addresses this hurdle by using artificial intelligence (AI) to allow quality engineering teams to realign their limited resources to spend more time validating and testing new release features while relying on Katalon to create, maintain, and run regression tests on existing application code.
