ITPEC IP October 2024 Question 46
ITPEC IP October 2024 — Question 46 of 100
The correct mapping is C for unit testing, B for integration testing, and A for system testing. A unit test can examine the internal logic and paths of an individual program, so it matches C. An integration test verifies interactions and interfaces between combined software components, so it matches B. A system test evaluates the complete system against requirements, including whether processing finishes within the planned operating time, so it matches A.
Answer (d)
Why not others:
- (a) incorrectly assigns the system-level timing requirement to unit testing and internal paths to system testing
- (b) assigns interface testing to the system level and path coverage to integration
- (c) assigns interface checking to a unit and timing to integration
Key rule: Unit tests inspect components, integration tests inspect interfaces, and system tests inspect end-to-end requirements.
