TDD …how?

Question

I\'m about to start out my first TDD (test-driven development) program, and I (naturally) have a TDD mental block..so I was wondering if someone could help guide me on where

Answer 1

When I was starting with TDD, I read these 3 rules by Uncle Bob that really helped me out:

1. You are not allowed to write any production code unless it is to make a failing unit test pass.
2. You are not allowed to write any more of a unit test than is sufficient to fail; and compilation failures are failures.
3. You are not allowed to write any more production code than is sufficient to pass the one failing unit test.

In a shorter version it would be:

1. Write only enough of a unit test to fail.
2. Write only enough production code to make the failing unit test pass.

as you can see, this is very simple.
