• Write unit tests:
  • Implement a FakeCoffeeCountStore;
• Run code before and after every test;

module 5 - Applying Test Driven Development

Summary:

• Test Driven Development (TDD):
  • Unit tests drive the implementation
  • Red, green, refactor
• Implement a requirement with TDD:
  • Write a test
  • Implement the requirement
  • Refactor the code

module 6 - Running Unit Tests Automatically

Summary:
