Run Relevant Tests

To run affected tests, this skill uses git diff to detect changed files and maps them to pytest and Jest targets, executing only the relevant test suites to reduce feedback time. It supports fast and deep execution modes.

Mapping changed files to pytest and Jest targets works by applying classification rules for test locations to build a deterministic execution plan, ensuring only tests impacted by the modified API or frontend code are run.

Fast mode includes only direct tests for the changed files, while deep mode expands execution to include reverse-dependency tests, providing broader coverage and surfacing failures with precise file and line references.

Yes, you can use this to run relevant tests for both frontend and API code changes. It maps modified files to the appropriate Jest or pytest targets and generates a clear execution plan with cross-referenced failure results.

To get precise file and line references for test failures, this skill cross-references the execution results and outputs suggested fixes alongside the test plan, helping you quickly locate and resolve issues in the changed code.
