Test First, Code Second
TDD feels slower at first but leads to better designed, more reliable code.
The TDD Cycle
- Write a failing test
- Write minimal code to pass
- Refactor
- Repeat
Benefits
- Better code design
- Living documentation
- Confidence in refactoring
- Fewer bugs in production
Common Pitfalls
Don't test implementation details. Test behavior and outcomes.
TDD is a skill that improves with practice.
