What is TDD? (Test Driven Development)

The tests are written before the code itself

TDD Goals

• Know when something breaks and where

• Know that the whole system works correctly

Workflow:

1. Chose something to work on

2. Build it based on specifications

3. Test it with small scripts

Workflow WITH TDD:

1. Chose something to work on

2. Write tests that would pass if products work

3. Keep building until all tests pass

The results are the same regardless of method - TDD forces you to prioritize tasks
