Change-Related Testing – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
A test type performed after modifications to confirm the change worked and did not introduce or uncover defects.
In simple words
Umbrella term for confirmation and regression testing — anything you run because something changed.
Exam tip
Change-related testing = confirmation testing + regression testing. Know both members of the family.

- Confirmation TestingAlso called re-testing — you rerun the exact steps that reproduced the bug to prove the fix works.
- Regression TestingAfter any change — bug fix, new feature, config update — you re-run existing tests to make sure nothing that used to work has broken.
- Maintenance TestingTesting done after go-live — patches, upgrades, migrations, retirements — to keep the running product safe.
