Testing

Testing

1. Black Box

   • Written from specs
   • No knowledge of implemention

2. White Box

   • Full knowlege of implementation
   • Written from code
   • Min: Code Coverage
     • BETTER: Branch Coverage

3. Why TDD?

   • Must think about how it will be used
   • Must design it so it's easy to test
   • Must think about what it's supposed to do
   • Prevents building things you don't need

4. Equivalency Class: different inputs, same coverage

5. Regression Testing: Re-execution of prev. tests

   • Ensures that changes in implementation have no introduced new defects

6. What?

   • Correctness: Does it do what it is supposed to
   • Robustness: Ranges + Errors
   • "Special" values
   • Typical cases
   • Boundary cases
