To keep test assertions aligned with API changes, you must update expected values in the same commit as the API evolution. This ensures disk state and tests stay synchronized to prevent CI failures.

CI tests fail after public interface updates because expected values in test assertions no longer match the evolved API signatures. Updating test assertions alongside API changes in the same commit prevents these regression failures.

Automating regression testing for API changes requires a disciplined pattern of updating corresponding test assertions in the same commit. This maintains synchronized tests across feature evolution and ensures CI feedback reflects code reality.

Yes, this approach specifically applies to codebases where tests rely on file counts, arrays, or feature lists. It requires tests to declare expected values so changes trigger corresponding updates to those assertions.

You should update test assertions during feature evolution whenever API signatures or public interfaces change. Applying test updates in the same commit as the API changes keeps the test suite aligned with code reality.

Yes, tests must declare expected values to stay synchronized with evolving APIs. This requirement allows changes to trigger corresponding updates to those assertions, ensuring disk state and tests remain aligned.
