Study Notes
Maintenance
- Modifying a component/system post-delivery serves to rectify defects.
- It also betters quality and adjusts to changed environments
- It helps understand the extent to which intended maintainers can modify a component/system.
- It tests changes to a working system or the impact of environmental changes.
Reasons for Maintenance Testing
- Systems can remain in service for many years
- Operational environments are corrected, changed, or extended over time.
- Testing during a system's life cycle is maintenance testing
System Evolution
- Systems operate over long periods.
- Corrections, enhancements, and environmental updates instigate changes
Testing Types
- Impact Analysis pinpoints the effect of changes
- Migration & conversion testing is important
- Testing levels & processes involve component, integration, system, and acceptance testing
- There exist formal and informal test planning
- Continuous test case updates are needed
Triggers for Execution
- Modifications such as enhancements, fixes, or environmental updates are key
- Another key is migration when moving to a new platform or system
- Retirement, involving archiving or data migration, is also key
Modification Testing
- Modification and maintenance involves planned updates, emergency fixes, and OS/database upgrades
- Changes can include hardware modifications
- The main focus is on integration and security
Migration Testing
- Migration aims to ensure stability on the new platform.
- It validates data conversion between systems.
Retirement Testing
- Retirement guarantees proper data archiving and retrieval.
- The regular validation of long-term storage solutions is important
Impact Analysis
- Impact analysis finds areas needing more regression testing
- This helps prioritize test efforts based on risk and supports decision-making regarding implementing changes
Challenges
- Impact analysis can be challenging because of outdated or missing specifications
- It can also be challenging due to lack of test documentation and traceability
- Another reason for difficulty is weak tool support and limited domain knowledge
- Strategies to maintain efficiency in regression testing include reusing existing test specifications, adapting test cases, and updating automated regression tests.

Description
Maintenance testing ensures long-term system reliability by addressing defects, improving quality, and adapting to evolving environments. Impact analysis, migration testing, and continuous test case updates are crucial. Testing is triggered by modifications, corrections and updates during the system's life cycle.
