A tester finds that system testing is started before the design phase is complete. What is the main issue with this in the V-Model?
ARequirements gathering is incomplete
BVerification is done after validation
CValidation is skipped entirely
DTesting phases are not aligned with development phases
Step-by-Step Solution
Solution:
  1. Step 1: Understand V-Model phase alignment

    The V-Model requires testing phases to start only after their corresponding development phases complete.
  2. Step 2: Analyze the problem

    Starting system testing before design completion breaks this alignment, causing potential test mismatches.
  3. Final Answer:

    Testing phases are not aligned with development phases -> Option D
  4. Quick Check:

    Test phases must follow dev phases [OK]
Quick Trick: Test only after matching dev phase done [OK]
Common Mistakes:
MISTAKES
  • Confusing verification and validation order
  • Assuming validation is skipped
  • Blaming requirements instead of phase timing
