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
