Test Driven Development – Best practices
Here are my practice when apply TDD, your idea is welcome:
- Write the simple test first, then write code. After that write test code for more complexity functionality
- Keep test code as simple as possible
- Run test immediately whenever complete writing code
- If spending much time for writing code, break the functionality into smaller ones and applying TDD for these pieces
- Whenever test code or productive code smells, refactor it immediately
- After writing code, use coverage tool to make sure productive code is covered 100% by test method. If some piece of code is not covered, your implementation has issue!
- Use mock objects if needed
- Automate unit test and intergrate them into CI server
