Automation comes very handy when it comes to regression testing. - Always ensure the automated regression testing suite up to date - define regression coverage matrix between automated regression suite and additional regression test cases to achieve required depth - based on the coverage matrix, device the run plan with tolerance to accommodate contingencies and defects - top of all this, keep the stakeholders informed on the approach and set the expectations on the outcomes

To define and ensure efficient regression testing, formulate high-risk areas, automating stable tests, and optimizing test suites. CI/CD integration accelerates feedback, while selective regression testing focuses on impacted features. Shift-left testing helps detect defects early, minimizing risks. Parallel execution speeds up test cycles, ensuring rapid validation. Regular test suite reviews remove redundant cases, enhancing efficiency. Continuous monitoring and analytics refine our approach, helping us balance speed and quality without compromising software integrity.
