allowed-tools:Bash(npx * npm *) mcp__claude-flow__hooks_pre-task mcp__claude-flow__hooks_post-task Read Write Edit
Follow the TDD London School (mock-first) approach:
- Write the failing test first -- define expected behavior with mocked dependencies
- Run the test -- confirm it fails for the right reason
- Implement minimal code -- make the test pass with the simplest solution
- Refactor -- clean up while keeping tests green
- Repeat -- add the next behavior
Before starting: mcp__claude-flow__hooks_pre-task({ description: "TDD: FEATURE_NAME" })
After completing: mcp__claude-flow__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]
