TDD may improve developer productivity

Developer workflow may improve DevEx, and Improving DevEx increases developer productivity.

Using The Three Dimensions of DevEx:

1. Feedback loops
   • Making red tests turn green.
2. Cognitive loads
   • Chunks abstraction of testing, user needs, design, refactoring, programming, into different chunks.
3. Flow state
   • The prerequisite of flow state is smaller goals, and TDD helps with that.
