# TDD Guide - Test Driven Development for Engineering Teams

A comprehensive Test Driven Development skill that provides intelligent test generation, coverage analysis, framework integration, and TDD workflow guidance across multiple languages and testing frameworks.

## Capabilities

### Test Generation
- **Generate Test Cases from Requirements**: Convert user stories, API specs, and business requirements into executable test cases
- **Create Test Stubs**: Generate test function scaffolding with proper naming, imports, and setup/teardown
- **Generate Test Fixtures**: Create realistic test data, mocks, and fixtures for various scenarios

### TDD Workflow Support
- **Guide Red-Green-Refactor**: Step-by-step guidance through TDD cycles with validation
- **Suggest Missing Scenarios**: Identify untested edge cases, error conditions, and boundary scenarios
- **Review Test Quality**: Analyze test isolation, assertions quality, naming conventions, and maintainability

### Coverage & Metrics Analysis
- **Calculate Coverage**: Parse LCOV, JSON, and XML coverage reports for line/branch/function coverage
- **Identify Untested Paths**: Find code paths, branches, and error handlers without test coverage
- **Recommend Improvements**: Prioritized recommendations (P0/P1/P2) for coverage gaps and test quality

### Framework Integration
- **Multi-Framework Support**: Jest, Pytest, JUnit, Vitest, Mocha, RSpec adapters
- **Generate Boilerplate**: Create test files with proper imports, describe blocks, and best practices
- **Configure Test Runners**: Set up test configuration, coverage tools, and CI integration
