  • Write one new test: The smallest you can think of that seems to point in the direction of a solution.
  • Watch it fail
  • Make the test pass by writing the least implementation code you can in the test method
  • Refactor as required. To create new structure that's not test code, apply these steps very strictly.
    • methods:
      • (preferred) Extract Method to create a new method in the test class
      • (if necessary) Move code into an existing method
    • types:
      • create classes only to provide a destination for Move Method.
      • Populate classes by moving definitions from tests, not the other way round.
  • The person not typing makes sure that these rules are being followed exactly.
