ISTQB CT-TAE – Certified Tester Test Automation Engineer — Question 63
What is a realistic expectation for the ratio of failures to defects?
Answer options
- A. There are usually more failures than defects.
- B. There are usually more defects than failures.
- C. They usually occur in the same proportion.
- D. Only defects should be tracked because a failure may not indicate a defect.
Correct answer: B
Explanation
The correct answer is B because it is common for a single defect to lead to multiple failures, indicating that defects are typically more numerous than failures. Options A and C are incorrect as they misrepresent the usual relationship, and option D is misleading since both failures and defects provide valuable insights for quality assurance.
