To keep tests in sync with API changes, update test assertions in the same commit as the source modifications. This disk-state alignment ensures test expectations match actual files, preventing flaky CI runs and false negatives.

Stale tests cause false positives and block contributors because test expectations no longer match the evolved public interfaces. Synchronizing test updates within the same commit maintains CI reliability and prevents regressions.

The best way to align test expectations with disk state is to enforce in-repo guidelines requiring test updates in the same commit as API changes. This ensures validated counts and expectations match actual files across CI runs.

You need to update test assertions for evolving public interfaces whenever API changes occur. Strict synchronization between source changes and corresponding test updates prevents false negatives and maintains a healthy project CI.

Yes, in-commit test synchronization works for projects with frequently evolving public interfaces. It ensures test counts and expectations are validated against disk state, maintaining CI reliability and preventing regressions when APIs change.
