Regression Testing is a First Class Citizen

In today’s fast-paced software development landscape, enterprise applications whether desktop, web, or hybrid are expected to deliver performance, reliability, and continuous updates. But with every new deployment, there’s a risk: what if something breaks that once worked perfectly? That’s where regression testing steps in — not as a luxury, but as a mission-critical practice. ⚙️ What is Regression Testing? Regression testing ensures that new changes (code fixes, enhancements, features) do not unintentionally break existing functionality. It’s about safeguarding your application’s integrity as it evolves. Most enterprises lack an in-depth strategy to provide a high level of coverage during regression testing. Generally, they just test the top 50 or 100 (or a similar number) of scenarios. The challenge comes from large systems that has functionality built over several years and not every test is captured in the regression suite. A large number of scenarios also takes several hours to run and certify the results. A right blend of top sunny scenarios for a certain number of hours is a sweet spot for many enterprises. But, I am making a case that you need a higher percentage of coverage for all business functionality during automated regression testing.
