The four test levels
Test levels group testing activities by the object under test, from the smallest piece up to the complete system in the user's hands.
| Level | What it verifies | Who usually does it |
|---|---|---|
| Component / Unit | An isolated piece of code | Development |
| Integration | The interaction between components | Development / QA |
| System | The full system end-to-end | QA |
| Acceptance | That it meets business/user needs | User / Business / QA |
Functional manual QA works mostly at the system and acceptance levels, where the application's observable behavior is tested.
