ITPEC FE Morning April 2020 Question 49
ITPEC FE Morning April 2020 — Question 49 of 80
Regression Test — verifying that unchanged areas are not broken by maintenance changes.
After software maintenance, a regression test checks whether locations that should not have been affected by the changes actually remain unaffected.
Why not others:
- (a) Integration test — verifies interaction between combined modules
- (b) Operational test — verifies system behavior under real operational conditions
- (d) System test — verifies the entire system against requirements
Key rule: If the question mentions "changes" + "unaffected areas" → regression test.
