Testing and Code Generation
Choose the narrowest test that exercises the changed behavior, then broaden only when shared infrastructure or integration risk justifies it.
Test Selection
| Change | Start with |
|---|---|
| Lint rule | just test-lintrule <ruleName> |
| One crate | cargo test -p <crate> or the crate's focused test target |
| Parser or formatter investigation | just qt <package> |
| CLI migration | focused biome_cli migration tests |
| Documentation code | just test-doc |
Use -- --show-output or --nocapture only when the test's diagnostic output is needed.
Quick tests are scratch space for inspecting CST, formatter IR, or one analyzer query. Persistent behavior belongs in the subsystem's normal fixture directory before finishing.
