There’s no correlation between a single test case and a single Red-Green-Refactor cycle. These short cycles allow you to go fast, which might feel counterintuitive at first, but really help you moving forward.

As by the 1st rule, we start by writing a test. However, the 2nd rule restricts us to write much of it. In fact, as soon as the test code fails to compile/execute, we must stop writing test code and write production code instead. This is where the 3rd rule […]

The three laws of Test-Driven Development are stated as follows:
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 […]

There are basically three ways to verify the outcome of a test:
- Verify the state of the Subject Under Test.
- Verify the return value of a method or function.
- Verify a value passed to a collaborator of the Subject Under Test.
That's it! Those are the […]
