Follow the TDD London School (mock-first) approach: 1. **Write the failing test first** -- define expected behavior with mocked dependencies 2. **Run the test** -- confirm it fails for the right reason 3. **Implement minimal code** -- make the test pass with the simplest solution 4. **Refactor** -- clean up while keeping tests green 5. **Repeat** -- add the next behavior Before starting: `mcp__plugin_ruflo-core_ruflo__hooks_pre-task({ description: "TDD: FEATURE_NAME" })` After completing: `mcp__plugin_ruflo-core_ruflo__hooks_post-task({ taskId: "tdd-FEATURE", success: true, storeResults: true })` Principles: - Mock external dependencies at boundaries - Test behavior, not implementation - One assertion per test when possible - Descriptive names: `should [behavior] when [condition]`
