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.
