Be prepared to apply good design

TDD can’t guarantee that we will have flashes of insight at the right moment. However, confidence-giving tests and carefully factored code give us preparation for insight, and preparation for applying that insight when it comes. —Chapter 12, Test-driven development: by example

When to review the design

Finally, when the list is empty is a good time to review the design. Do the words and concepts play together? Is there duplication that is difficult to eliminate given the current design? (Lingering duplication is a symptom of latent design.) —Chapter 17, Test-driven development: by example
