Rule 1: I do not write any production code unless it is to make a failing unit test pass !

Rule 2: I do not write anymore of a unit test than is sufficient to fail !

Rule 3: I do not write more production code than it is sufficient to pass the failing test !

Test Driven Development (TDD)

Write test

See it fail

Write code to pass
