Summary

TDD gives us:

• Get more feedback if I make the steps as small as I can.
• I have safety net by tests when I refactoring.

Critical things in TDD:

• test path - different test path tends to different results,see different from katas Unique Sorted Array & Unique Sorted Array2,if I choose test path correctly then my work stably,otherwise I could lost myself.
• feedback - short feedback is critical too,they can give you most of things if you think the right things,e.g:misunderstanding,design decisions,otherwise it's waste your time.
