Justification. Justification WRONG – Exhaustive test is impossible, regardless .. 253
- WRONG – Exhaustive test is impossible, regardless of it being manual or automated.
- WRONG – Exhaustive testing is impossible, regardless of the amount of effort put into testing (Principle # 2)
- CORRECT – Principle #2 states: “Testing everything (all combinations of inputs and preconditions) is not feasible except for trivial cases”
- WRONG – This statement is contradicting Principle #1: Testing shows presence of defects: Testing can show that defects are present, but cannot prove that there are no defects.
Question 2 K1
Which of the following statements is the MOST valid goal for a test team?
|A||To determine whether enough component tests were executed within system testing.|
|B||To detect as many failures as possible so that defects can be identified and corrected.|
|C||To prove that all defects are identified.|
|D||To prove that any remaining defect will not cause any failures.|
- WRONG – Component testing is not part of System testing.
- CORRECT – This is the main role of a test team.
- WRONG – Principle #1 states that exhaustive testing is impossible, so one can never prove that all defects were identified.
- WRONG – To make an assessment whether a defect will cause a failure or not, one has to detect the defect first. Saying that no remaining defect will cause a failure, implicitly means that all defects were found. This contradicts Principle #1.
