Line 119:

* Write [[unit test]]: The programmers write a minimal test that should fail because the functionality hasn't been fully implemented in the production code.

* Watch the new test fail: The programmers verify the test does indeed fail. While it may seem like a waste of time, this step is critical because it verifies that your belief about the state of the production code itis correct. If the test does not fail, the programmers should determine whether there is a bug in the test code, or that the production code does support the functionality described by the new test.

* Write code: The programmers write just enough production code so the new test will pass.

* Run test: The unit tests are executed to verify that the new production code passes the new test, and that no other tests are failing.
