# Julia test changes
Use this when you change or add a Julia test.
- If you have changed a test (e.g. `foo`), run `make test-revise-foo` for the
corresponding test to ensure that the test is still passing with your changes.
- If you are adding a new test, add it to an existing test file. Do not create a
new test file unless explicitly instructed.
- Write one comment at the top of the test to explain what is being tested.
Otherwise keep comments minimal.
- Use the environment variable `JULIA_TEST_FAILFAST=1` to make tests fail fast.
- Do not coordinate with fixed `sleep`s — loaded CI machines break any fixed
delay. Synchronize on observable state (readiness markers, round-trips), or
retry.
