ITPEC FE Morning October 2021 Question 46

Conducted by users to confirm the software is complete and meets the business needs — acceptance testing is the users' final check before they accept the system.

The test levels differ in who runs them and what they check:

• •Unit test — developers, each module.
• •Integration test — developers or testers, the interfaces between modules.
• •System test — the development side, the whole system against functional and non-functional requirements such as performance.
• •Acceptance test — the users or ordering party, fitness for their business.

Answer (d)

Why not others:

• •(a) — verifying response time and other performance items by developers is performance testing within the system test.
• •(b) — checking interfaces and linkages between software parts is integration testing.
• •(c) — verifying functional requirements on the development side is the system test; acceptance is judged by the users, not the project manager.

Key rule: Acceptance testing is run by the users or ordering party and judges business fitness; every earlier test level is run by the developing side.
