| description | OpenAgentd TDD workflow — write a failing test before the code that makes it pass, reproduce a bug with a test before fixing it. Use when implementing any logic, fixing any bug, or changing any existing behavior in backend (pytest) or frontend (Bun/RTL) code.
|
Write the test first. It must fail for the right reason before you write the
code that makes it pass. Tests are proof — "seems right" is not done.
When NOT to use: pure config, docs, or static content changes with no behavioral impact.
Environment specifics (run commands, placement, fixtures, mock rules) live in oad/testing — load it now.
1. RED — write a failing test
Before touching implementation code, write the test and confirm it fails for the expected reason, not a typo or import error.
Run it:
uv run pytest tests/path/to/test_file.py::test_new_behavior -q
cd web && bun test src/__tests__/components/Foo.test.tsx
2. GREEN — minimal implementation
Write the smallest change that makes the test pass. Don't add branches, config, or abstraction the test doesn't require yet.
3. REFACTOR — clean up
With the test green, improve naming/structure without changing behavior. Re-run after every refactor step.
uv run pytest -n 4 -q
cd web && bun test --parallel
The Prove-It Pattern (bug fixes)
Do not start a bug fix by editing implementation. Start by writing a test that reproduces the bug:
Bug report → write a failing test → confirm it FAILS for the right reason
→ implement the fix → confirm it PASSES → run the full suite (no regressions)
Once the reproduction test is green after the fix, hand off to oad/debug step 6 (verify and report) if this was part of a debug session, or to oad/commit to ship the fix.
