Regression testing is the process of analysing and evaluating the unchanged parts of business systems. The idea is that with these tests, you can ensure any updates to your business operations haven’t led to unexpected side-effects or consequences. 

Running regression tests helps organisations to stay ahead of the curve, even in agile environments where processes are constantly changing. However, to make the most out of this process, teams need access to the correct tools. Today, we’re going to explore ten of the best regression testing tools available for companies right now.
