What Is Regression Testing?
Regression testing is a manual or automated testing activity performed specifically when you have added changes or updates to your application. After implementing your changes, you will use a regression test to determine if your application still functions as it should, or if the changes have created new bugs.
Why Should You Use Regression Testing?
Regression testing is crucial for any kind of software that will go through changes or updates after launch. In the modern world, most applications fall under this category. After all, many apps, websites, and even video games go through updates to accommodate technological changes, aesthetic changes, and more.
Regression testing will ensure that those updates won’t break your application by detecting any problems before the update is released to the public.
