ITPEC IP April 2022 Question 48
ITPEC IP April 2022 — Question 48 of 100
An acceptance test is performed by or for the user to confirm that delivered software satisfies the agreed requirements. It evaluates whether the system is fit for actual business use and provides the basis for the customer to accept the delivery.
Answer (a)
Why not others:
- unit testing verifies individual program units
- integration testing verifies interactions among combined modules
- system testing verifies the complete integrated system, typically from the developer or test organization's perspective
Key rule: Testing progresses from units to integration to the complete system; user acceptance is the final confirmation against business needs.
