Baseline Management

Maintain trusted baselines for regression and snapshot tests by defining baseline sources, versioning them with code, and enabling PR reviews for updates to detect significant deviations. This ensures meaningful changes are tracked.

Automate baseline comparisons in CI pipelines by integrating baseline versions with code changes. This allows the CI system to automatically compare new test outputs against stored baselines during continuous integration runs.

Manage baseline updates without losing historical data by archiving historical baseline data. Facilitate updates through Pull Requests to ensure changes are reviewed while previous baselines remain stored for reference.

Update snapshot baselines after a UI component change by running `npm test -- -u`. This command updates the stored snapshots to establish the new trusted baseline for future comparisons.

Yes, you can use this for performance testing baselines as well as UI snapshots. The system manages baselines for various testing types including regression, performance, and snapshot tests to identify significant deviations.

Version baselines with code changes to ensure baseline updates are reviewed through Pull Requests. This process maintains trusted baselines by linking test expectations directly to the codebase state that produced them.
