Regression testing is the practice of re-running existing test cases to ensure that recent code changes have not unintentionally broken previously working functionality. As applications evolve with new features, bug fixes, and refactoring, regression testing acts as a safety net that protects core behavior.

Unlike exploratory or one-time tests, regression tests are designed to be repeatable and stable. They typically cover critical user journeys, APIs, integrations, and edge cases that directly impact business functionality. Without effective regression testing, even small changes can introduce silent failures that surface only in production.

With the rise of CI/CD and frequent deployments, regression testing has shifted heavily toward automation. Automated regression testing suites allow teams to validate changes quickly, reduce manual effort, and maintain confidence in releases without slowing down delivery. API-level regression tests, in particular, provide faster feedback compared to UI-heavy suites and are easier to maintain.

A well-balanced regression strategy focuses on high-risk areas, avoids redundant test cases, and evolves alongside the product. The goal is not to test everything repeatedly, but to test the right things consistently.
