Baseline testing focuses on establishing a known, trusted version of software behavior that can be used as a benchmark for future releases. By capturing key functional or performance characteristics at a specific point in time, teams gain a clear reference for identifying unexpected changes.
This approach is especially valuable when systems are updated frequently or when multiple teams contribute to the same codebase. Baseline testing helps QA and development teams spot deviations early, whether they appear as functional regressions, performance drops, or changes in system responses.
Over time, baseline testing supports better decision-making by providing historical insight into how an application evolves. It enables teams to validate improvements confidently while ensuring that new changes remain aligned with established quality standards.
