The ‘T’ word, that can change the way you think about code.

• You are not allowed to write any more test code than is sufficient to fail, and not compiling is failing.

• You are not allowed to write any production code unless it is to make a failing test pass

• You are not allowed to write any more production code than is sufficient to pass the one failing unit test.
