What is Regression Testing 

Regression testing, as used in ERP, is the process of retesting updated or modified features inside an ERP system in order to ensure sure that the performance or functionality of the system haven’t been negatively impacted by recent modifications.It involves running previously conducted tests again to validate that new changes haven’t caused unintended consequences or introduced errors in the ERP system.  

How does regression testing work? 

Regression testing works by re-executing select test cases or scenarios that cover critical functionalities of a software system, such as an ERP. When changes or updates are made to the system, these tests are rerun to ensure that the modifications haven’t introduced new bugs or affected existing functionalities negatively. 

It aims to validate that the recent changes haven’t caused any unintended side effects or regressions in the system’s behavior.  

When should regression testing be performed? 

Regression testing should be performed whenever there’s a change in the software system, be it a modification, addition of new features, bug fixes, updates, or integration of new modules. It’s crucial before major releases, after critical fixes or patches, and when system configurations are altered.  

Essentially, it’s necessary whenever alterations occur to ensure the existing functionalities haven’t been compromised and that new changes haven’t introduced unexpected errors or regressions in the system.
