White- vs. black-box testing

• A common dichotomy for testing is white-box vs. black-box testing

• In white-box, the tester sees the code

  • A key question is, “What code is covered?”
  • Often done earlier

• In black-box, the tester sees the specification but not the code

  • The primary question is, “Does the code satisfy the specification for specific test cases?”
  • Often done later
