Your question is Applying TDD. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What is TDD and how do you apply it in your work?
Keep your answer focused on how the red, green, refactor cycle works in practice, not just the definition. Explain how you decide what to test first, and what kinds of code are a good or bad fit for TDD.
