Since regression testing can be used for many different software applications, it can be a crucial tool for software development because it allows developers to analyze problems or issues that might be caused by introducing new programming code into existing programs or applications.

Regression testing can be executed within a partial or full selection of previously completed test cases (the group of previously modified and tested applications). Regression testing is a type of test performed on software that has recently undergone a code or program change to ensure the software and its features are unaffected by the coding changes. In this article, we'll explore what regression testing is, the importance of regression testing, how to do it and when it's appropriate to execute a regression test.
Additionally, regression testing allows software developers to continuously improve current software products and applications. When a software program is modified or changed with new codes and requirements, a software developer may use regression testing as a means to ensure the changes made to the program do not adversely affect its existing features and functionality. Regression testing can be a crucial step in the software development process.
