Summary: Testing Strategies

  • "Big Bang" approach
    • you write the entire program
    • then you design and run some test cases
    • generally a bad idea
  • "As You Go" Testing
    • you write a small piece of code, then you test it
    • integrate it with other tested pieces and test again
    • repeat iteratively until the entire program has been constructed
  • Regression Testing
    • re-run all testing after any changes to the system
