update-test

What problem does it solve?

Update-test helps teams repair test suites that fail after an intentional change to the code’s public contract, ensuring tests continue to validate the new expected behavior rather than being blindly loosened or removed.

Core Features & Use Cases

• Contract-change test alignment: Update assertions, fixtures, and golden files so tests reflect the new function/field/error shapes.
• Meaning-preserving test maintenance: Decide whether each affected test remains valuable, should be deleted cleanly, or consolidated with another test.
• Regression coverage for new edge cases: Add at least one new test covering any new validation or error behavior introduced by the contract change.
• Use case: A renamed return field or changed error type breaks existing tests after a planned refactor; update-test guides you to systematically migrate expectations and keep coverage meaningful.

Quick Start

Tell the AI to update the repository’s failing tests to match the newly intended contract change by identifying every affected assertion, updating or deleting tests as appropriate, adding new coverage for the newly introduced edge cases, and then running the full test suite plus the linter.
