Regression testing plays a key role in ensuring that new code changes do not negatively impact existing functionality. In environments with continuous development and frequent updates, even small modifications can introduce defects that affect critical features.

By running regression testing consistently, teams can validate that previously working features, integrations, and workflows remain stable after updates. Automated regression tests provide quick and reliable feedback, while selective manual testing helps cover complex or high-risk areas.

Incorporating regression testing into CI/CD workflows allows teams to detect regressions early, reduce release risks, and deliver stable software despite rapid change.
