Test Driven Development

1. Dynamic verification

2. Static verification

3. Formal verification

4. Three stages of TDD

   • Make it fail
   • Make it work
   • Make it better
     • Refactoring
       • Collapse hierarchy
       • Extract Method
       • Consolidate expressions
       • Extract class

5. Code Smells

   • Bloaters
   • OO Abusers
   • Change Preventers
   • Dispensables
   • Couplers
