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
