SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps validate code changes by intelligently selecting and running the appropriate test suites, reducing wasted testing time and avoiding full-suite runs when unnecessary.

Core Features & Use Cases

  • Smart test selection: Discover and run only the test suites affected by your changes.
  • Minimal venvs: Validate with 1-2 venvs initially to speed iteration.
  • Docker-integrated: Automatically manages Docker services when needed.
  • Dry-run support: See what would run before executing tests.

Quick Start

List edited files and discover matching suites: scripts/run-tests --list <edited-files> Run the targeted tests in a chosen venv: scripts/run-tests --venv <hash> -- -- (pytest args)

FAQPage Schema
How do I run only the tests affected by my code changes?▼

Smart test selection identifies which test suites are affected by your edits. Use scripts/run-tests --list <edited-files> to discover matching suites, then run only those tests instead of the full suite, reducing validation time significantly.

Can I validate changes with Docker services automatically?▼

Yes. The Skill automatically manages Docker services when needed for testing, eliminating manual setup and teardown. This works seamlessly with targeted test runs across your affected code.

How do I speed up test iteration with minimal virtual environments?▼

Validate with 1-2 venvs initially rather than creating multiple environments. Run scripts/run-tests --venv <hash> to execute targeted tests in a chosen environment, accelerating feedback during development cycles.

What's the best way to preview which tests will run before execution?▼

Use dry-run support to see what would execute without actually running tests. This lets you verify the correct test suites are selected before committing to a full validation run.

Does this work for test infrastructure changes as well as code edits?▼

Yes. The Skill handles validation for source code edits, bug fixes, new features, and test infrastructure changes by intelligently discovering affected test suites for each type of modification.
