Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
Testing that focuses on whether an application still works correctly when its third-party dependencies are updated or changed.
In simple words
Making sure upgrades to libraries don't break your app.
Exam tip
Combine with dependency scanning to catch both security and behaviour issues.

- 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.
- Integration TestingAfter units work alone, you plug them together and check the seams — API calls, data hand-offs, contracts.
