Study Notes
- Maintenance involves modifying a component or system post-delivery for defect correction, quality improvement, and adapting to changed environments
- Maintainability is the extent to which intended maintainers can modify a component or system
- Maintenance testing tests changes to an operational system or the impact of changing the operational environment on a system
Need for Maintenance Testing
- Systems in service require maintenance for years or decades
- Systems and their operational environments need correction, changes, and extensions
- Testing during the life cycle phase constitutes 'maintenance testing'
System Longevity & Changes
- Systems operate to remain operational over long periods of time
- Corrections, enhancements, and environmental updates cause necessary changes
Testing Aspects
- Assessing change effects is key when analyzing change impact
- Testing includes component, integration, system, and acceptance testing
- Test planning that is both formal and informal is required
- Continuous test case updates are important
Triggers for Maintenance Testing
- Modifications driven by enhancements, fixes, or updates to the environment
- Migration from movement of systems to new platforms
- Retirement via data archiving or migration
Modifications & Maintenance Testing
- Maintenance testing includes planned updates, emergency fixes, and OS/database upgrades
- Hardware changes may be a factor, including IoT devices
- Integration and security testing gets considerable focus
Migration Testing
- Stability is a necessity in the new platform
- Data conversions between systems are validated
Retirement Testing
- Data archiving and retrieval must be ensured
- Periodic validation of long-term storage solutions should be performed
Impact Analysis and Regression Testing
- Impact analysis determines areas requiring more regression testing and helps prioritize efforts based on risk
- Decision-making is supported when changes must be implemented
Challenges in Impact Analysis
- Specs can often be outdated
- Lack of test documentation and traceability is common
- Weak tool support and limited domain knowledge can be an issue
How to properly Maintain Efficiency in Regression Testing
- Test specifications are reused and cases are adapted to changes, automated regression tests are updated
