+When adding tests:
+
+- **Design before you write.** Answer four questions first: what is the module
+  for, what is its I/O contract, what failure am I guarding against, and what is
+  the cheapest level that catches it (unit over integration over e2e)?
+- **Reuse before create.** Extend existing test files, `conftest.py` fixtures, and
+  helpers; add a new file only when no nearby suite fits.
+- **Test behavior with intent.** Assert observable outcomes through public APIs;
+  state why in the name or docstring. Skip trivial wiring; flaky tests are worse
+  than no tests.
+- **Keep it minimal.** One behavior per test and the smallest setup that
+  triggers it; if the test diff dwarfs the code change, cut scope.
+- **No one-off kernel benchmarks in `tests/`.** Put kernel perf work in
+  `benchmarks/kernels/`; prove correctness in existing pytest suites.
+- **Run model evals for model-affecting changes.** Search `tests/evals/` or use
+  `vllm bench` and include results in the PR — do not wait for reviewers to ask.
+

+[`docs/contributing/model/tests.md`](docs/contributing/model/tests.md).
