Turning Comments to Code

The Change

Transform your comments unit test into a running unit test.

The Value Proposition

Writing a unit test can be hard, even though we have already defined it in comments. Writing that test incrementally, from the bottom up, provides the following advantages:

1. Reduce mental overload by solving one problem at a time.
2. Focus on the most valuable parts first.
3. End up with a clearer, more expressive test.
