    Regression testing is the process of re-running existing test cases to ensure that recent code changes have not broken previously working functionality. It acts as a safety net, helping teams confirm that enhancements, bug fixes, or refactoring efforts do not introduce unintended side effects.

    As applications grow more complex, regression testing becomes essential for maintaining confidence in each release. Even small changes can impact interconnected components, and regression tests help uncover these issues early, before they reach production. This is especially important in agile and continuous delivery environments where changes are frequent.

    Regression testing is often supported by automation to make it practical and repeatable. Automated regression suites allow teams to run tests quickly after every build, while manual regression testing is still useful for high-risk or exploratory scenarios.

    Overall, regression testing ensures continuity and reliability, enabling teams to move forward with changes while preserving the stability of existing features and user experience.
