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
