Change-Related Testing is a type of software testing that focuses on validating modifications made to a system, ensuring that new changes, enhancements, or fixes function correctly and do not introduce new defects. This includes testing activities like regression testing and re-testing. Key aspects include:
Purpose:
- Verify changes work as intended
- Ensure changes don’t introduce new issues
Types:
- Confirmation testing: Verify fixed defects
- Regression testing: Check unaffected areas
Scope:
- Changed components
- Impacted areas
- Critical system functions
Techniques:
- Re-execution of existing tests
- Creation of new tests for changes
- Impact analysis to guide testing
Challenges:
- Determining appropriate test scope
- Managing time constraints
- Balancing thoroughness with efficiency
Change-Related Testing helps maintain system quality during and after modifications.
