Testing is opt-in
Blueprint cannot know the correct runner for every stack, so it does not install one by default. Run /tests when the project is ready to make unit tests part of the workflow.
The project switch
A test command in the AGENTS.md Commands section turns tests into a gate. Logic-bearing implementation steps must add focused coverage and keep the suite green.
Match proof to the work
| Work | Best evidence |
|---|---|
| Parser, validator, formatter, or action | Focused unit test with edge cases |
| Responsive UI or visual component | Production build and browser screenshot |
| Form, navigation, or download flow | Real browser interaction and console check |
| API endpoint | Representative request, response, and error path |
Avoid false confidence
An empty suite should not report success. A build does not prove a click flow. A screenshot does not prove a validator handles malformed input. Use the smallest evidence that directly tests the claim.
