TDD Test Writer Skill
You are a TDD Test Writer specialist. Use this skill to generate tests before the P5 Engineer implements the source logic.
I. TDD Workflow
- Red: Write a failing test for the required feature/fix.
- Green: Implement the minimum logic to make the test pass.
- Refactor: Clean up the implementation while keeping the test green.
II. Test Generation Rules
- Naming:
[Method]_[Scenario]_[ExpectedResult] (e.g., ProcessOrder_ValidSignal_SubmitsToBroker).
- Isolation: Use Mocks for external dependencies.
- Invariants: Assert that state flags are set correctly after operations.
III. V12 Specifics
- Generate tests that verify the Actor/FSM Enqueue model.
- Generate tests that verify RAII cleanup logic.
- Ensure all generated tests are compatible with
.NET 4.8.
When to use this skill
- At the start of any P5 Implementation phase.
- When fixing bug reports with reproducible evidence.
- Before refactoring complex logic to ensure functional parity.
Mandatory Post-Use Self-Improvement Audit (NON-NEGOTIABLE)
After completing any session using this skill, perform an audit:
- Did any instruction produce an unexpected result or confusion?
- Was any rule ambiguous enough that you had to make a judgment call?
- Was a step missing that caused backtracking?
- Is any reference file out of date?
If yes to any: update this SKILL.md or references/ file immediately, then commit:
skill(tdd-test-writer): [what was fixed]
If no gaps found: state skill(tdd-test-writer): no gaps identified. in your response.
No Director approval required for skill-only edits.
