Write minimal, high-signal tests that protect language semantics, diagnostics, and regressions.
Workflow
1) Choose the right test bucket
tests/run-pass/: should compile and run
tests/compile-fail/: should fail to compile
tests/ui/: diagnostics/error message matching via //@ error-pattern:
compiler/tests/: Rust integration tests for compiler subsystems
2) Keep tests small and explicit
Avoid relying on features listed as missing in compiler/docs/KNOWN_LIMITATIONS.md.
Prefer one behavior per test file; add //@ ignore if it’s documenting an aspirational feature.
3) Run the narrowest validation first
If you changed Rust compiler code: cd compiler && cargo test <name>
If you changed language behavior: run the smallest relevant test subset first
