Test Workflow

test-engineer is the canonical owner for DegenExus test authoring and coverage analysis. test-writer is a read-only deprecated alias and must not be routed for new work.

Steps

1. Identify the source of truth and current test patterns.
2. For bugs, write or describe the failing regression first and record failing_before.
3. Use FSV-AAA where practical: PRE source-of-truth read, one ACT, POST reread, expected DIFF assertion.
4. Cover boundary/equivalence classes: empty/zero, min/max boundary, malformed/adversarial input, and ordering/concurrency where applicable.
5. Use pytest-mock's mocker fixture; do not import unittest.mock directly.
6. Mock LLM providers, yfinance/network calls, time, and randomness.
7. Run targeted pytest first, then broader regression tests when feasible.
8. Emit .claude/rules/evidence-schema.yml fields with edge_cases, failing_before, and passing_after evidence when applicable.
