CSI Testing & Quality Assurance Flashcards

Which testing phase validates that integrated systems exchange data correctly and meet business requirements before go-live?

Answer: User Acceptance Testing (UAT)

UAT is the final validation phase where end-users confirm that integrated systems meet business requirements before production deployment.

A system integrator must verify that two enterprise applications exchange messages without data loss. Which testing approach is most appropriate?

Answer: End-to-end integration testing

End-to-end integration testing validates complete message flows across system boundaries to ensure no data is lost in transit.

What is a 'test harness' in the context of system integration testing?

Answer: A collection of stubs and drivers that simulate system components

A test harness is a framework of stubs and drivers used to simulate missing or unavailable components during integration testing.

During integration testing, a 'stub' is used to:

Answer: Simulate a downstream component that is not yet available

A stub simulates a downstream dependency, returning predetermined responses so the component under test can be validated independently.

Which defect classification indicates a critical system integration failure that blocks all further testing?

Answer: Blocker/Showstopper

A blocker or showstopper defect halts the entire testing effort because the core integration path cannot function until it is resolved.

What does 'traceability matrix' provide in a CSI testing project?

Answer: Mapping between requirements and corresponding test cases

A traceability matrix maps each business requirement to one or more test cases, ensuring complete test coverage.
