ITPEC FE Subject A April 2024 Question 38
ITPEC FE Subject A April 2024 — Question 38 of 60
Integration Testing — verifying interfaces and linkages between program modules.
Integration testing checks that separately developed modules work correctly together, focusing on data flow and control flow across module boundaries.
Why not others:
- (a) Acceptance test — validates the system against business/user requirements (done by the customer)
- (c) Qualification test — verifies the entire system meets its specification (synonym for system testing)
- (d) Unit test — tests a single module in isolation, not inter-module linkages
Key rule: "interfaces between parts" → integration test. "Whole system vs spec" → system/qualification test. "Customer signs off" → acceptance test.
