Regression testing is critical to ensure that new code updates did not negatively affect existing functionalities. However, not all QA teams are managing regression testing the right way. In this article, we list the top 10 regression testing best practices to help you achieve better efficiency.

From the technical perspective of QAs, investing in test automation is no longer a nice-to-have, but a necessity. However, the problem arises when they seek alignment with the non-technical stakeholders. To secure leadership buy-in, it is important that you translate the value of test automation into business value. More than just faster releases, it is also about having lower risk, better customer experience, and a stronger competitive edge.

Regression testing is notoriously repetitive and time-consuming. As your software grows in complexity, manually testing every existing features is just counter-productive. This is why regression testing is an ideal potential for automation. One of Katalon's customers, Liberty Latin America, upon adopting regression test automation, has seen 50% decrease in testing time, which ultimately translates into rippling benefits across the entire QA process.

API is the backbone of many software architecture. However, it is also one of the major points of technical conflict. When a major code update happens, it is really important to check on these APIs to ensure that those code modifications did not inadvertently break existing functionality. This is why API regression testing should be considered in your regression test planning.

We recently interviewed 1,400 QA professionals in the State of Quality Report 2025 to arrive at these test automation statistics for 2025. 72% of them have up to 10 years of experience, and 16.2% of them have from 6-9 years of experience. The topics we surveyed include: Here are some notable statistics from the survey: Here are some more insights you may find valuable: Find these insights fascinating?

The “organic” evolution of a software tester should follow the organic evolution of an organization’s QA maturity. A tester can be conveniently imagined as an organism existing within a larger ecosystem (in our case, the organization). An organism does not exist in isolation. Rather, it responds to, adapts to, and evolves along with the environment in which it finds itself.

Hybrid testing is the testing approach which balances manual with automated testing to achieve the best of both worlds. It is effective because software testing by nature requires both the creativity of humans and the automating powers of machines.

Enterprise organizations invest heavily in test automation to achieve faster releases, improve test coverage, and reduce costs. According to our recent survey of over 1,400 quality professionals, while automation is a top priority, organizations face significant challenges in realizing its full potential.
