  2. Summary • Testing periods and evolution of testing models • Software testing timeline

  3. Testing Periods • Until 1956: Debugging-oriented period • 1957–1978: Demonstration-oriented period • 1979–1982: Destruction-oriented period • 1983–1987: Evaluation-oriented period • 1988– …: Prevention-oriented period

  4. Debugging-oriented Period( … - 1956) • No consensus between testing and debugging: • For some people, testing is a sub-activity of debugging • For others, debugging and testing are the same activity • For still others, debugging and testing are two distinguished activities • The main focus is on the hardware not on the software

  5. Demonstration-oriented Period (1957 - 1978) • People realize bugs can have a negative impact • Charles Baker makes a clear distinction from debugging and testing: • Debugging: Make sure the program runs • Testing: Make sure the program solves the problem • Testers should write tests having in mind they have to be successful

  6. Destruction-oriented Period(1979 – 1982) • In 1979, G.J. Myers writes his famous book:

  7. Destruction-oriented Period(1979 – 1982) • Myers defined testing as “the process of executing a program with the intent of finding errors” • Tester should write tests having in mind they have to fail • Myers: Showing a program has bugs is more efficient than showing a program has no bugs. • Google Testing Blog: “If it ain't broke, you're not trying hard enough”

  8. Evaluation-oriented Period(1983 – 1987) • Guideline for Lifecycle Validation, Verification and Testing of Computer Software • Methodology that integrates analysis, review and test activities to provide product evaluation during the software life cycle • A tester can start working on the software life cycle from the very beginning • A tester can review and gives his feedback on the specifications of the features to be implemented • For instance a tester can detect that: • User needs won’t be fully satisfied with the feature • A feature has some holes and thus cannot be correctly tested in some particular cases • etc.

  9. Prevention-oriented Period(1988 – …) • Quality metrics: • Code coverage • Complexity • etc. • Rule coding • Comments in the code • etc. • Continuous Inspection

  10. Prevention-oriented Period(1988 – …) • Quality metrics: • Code coverage • Complexity • etc. • Rule coding • Comments in the code • etc. • Continuous Inspection
