Writing tests first gives us a clear perspective on the API design, by getting into the mindset of being a client of the API before it exists.
Good tests serve as great documentation of expected behavior.
It gives us confidence to constantly refactor our code because we know that if we break anything our tests fail.
If tests are hard to write its usually a sign architecture could be improved. Following RGR ( Red — Green — Refactor ) helps you make improvements early on.
