Study Notes

Requirements Traceability

  • Users are most interested in the system meeting its requirements, and testing should be planned to individually test all requirements.

Static and Dynamic Verification

  • Software inspections:
    • Concerned with analyzing the static system representation to discover problems.
    • May be supplemented by tool-based document and code analysis.
  • Software testing:
    • Concerned with exercising and observing product behavior.
    • The system is executed with test data and its operational behavior is observed.

Verification and Validation (V&V)

  • Requirements are traced from high-level specification to detailed design and program testing.

Program Testing

  • Can reveal the presence of errors, but not their absence.
  • A successful test is one that shows that a requirement has been properly implemented.

Testing and Debugging

  • Defect testing and debugging are distinct processes.

Key Points

  • Program inspections are very effective in discovering errors.
  • Program code is systematically checked by a small team to locate software faults in inspections.
  • The Cleanroom development process depends on:
    • Incremental development.
    • Static verification.
    • Statistical testing.
