Test Driven Development

Test a little. Code a little.

Test driven development
- Start by writing the test cases
  - Initially, all test cases are likely to fail
- The test cases serve both as program specification and documentation
- Implement the program
  - The implementation is done when all tests succeed
- Refactor the program to improve its quality
  - Do full regression test in between each modification
