Baseline testing is a critical practice for establishing a reference point that represents a system’s expected behavior, performance, or functionality at a given stage. Once this baseline is defined, future builds and releases can be compared against it to quickly identify unintended changes, regressions, or performance degradation.
By consistently validating new versions against an established baseline, QA teams can detect subtle issues that may not surface during isolated test runs. Baseline testing is especially valuable in agile and CI/CD environments, where frequent code changes increase the risk of breaking existing functionality.
This approach also supports data-driven decision-making by helping teams track trends in system behavior over time. Whether used for performance benchmarks, functional validation, or reliability checks, baseline testing plays a key role in maintaining software quality, improving release confidence, and ensuring long-term system stability.
