Test-Driven Development patterns and practices.

When to Use

• Writing new functionality
• Refactoring existing code
• Ensuring test coverage

TDD Cycle

1. Red - Write failing test
2. Green - Make test pass
3. Refactor - Improve code

Best Practices

• Write smallest test first
• Test one thing at a time
• Use descriptive test names
• Maintain fast test execution
• Achieve high coverage

Success Criteria

Tests written before implementation, all passing.
