Testing Concepts interview questions — Medium
249 medium-level Testing Concepts questions from our Manual Testing bank, each with the correct answer and an explanation of why it is correct.
What this covers
Testing Concepts appears throughout Manual Testing interviews. At medium level, interviewers are typically checking that you have used it in practice: what you configured, what broke, and how you knew it worked. Work through these, then explain your answer out loud; the second part is what interviews actually test.
20 example questions
1. "Human mistake → flaw in artifact → observable wrong behavior" — in Concepts, this describes which of the following?
- A. Debugging.
- B. Static analysis.
- C. Error, defect, failure.correct
- D. Traceability.
Why: error, defect, failure: Human mistake → flaw in artifact → observable wrong behavior.

- A. Error, defect, failure.
- B. Debugging.
- C. Traceability.
- D. Inspection.correct
Why: inspection: Formal, moderated review with defined roles and metrics.
3. "Developer activity of locating and fixing defect causes" — in Concepts, this describes which of the following?
- A. Debugging.correct
- B. Inspection.
- C. Traceability.
- D. Static analysis.
Why: debugging: Developer activity of locating and fixing defect causes.
4. "Tool-based examination of code without executing it" — in Concepts, this describes which of the following?
- A. Static analysis.correct
- B. Walkthrough.
- C. Error, defect, failure.
- D. Debugging.
Why: static analysis: Tool-based examination of code without executing it.
5. Which statement correctly describes Concepts?
- A. Passing all tests proves the software contains zero defects.
- B. Independence in testing increases objectivity in finding defects.correct
- C. Static testing requires executing the compiled application.
- D. Verification and validation are precisely identical activities.
Why: Author bias makes self-testing less effective at higher levels.
6. Which of the following statements about Concepts is TRUE?
- A. Verification and validation are precisely identical activities.
- B. Fixing a defect in production costs the same as fixing it during requirements.
- C. Static testing requires executing the compiled application.
- D. Verification asks 'are we building the product right'; validation asks 'are we building the right product'.correct
Why: Verification checks conformance to spec; validation checks user needs.

- A. Error, defect, failure.
- B. Test basis.correct
- C. Static analysis.
- D. Dynamic testing.
Why: test basis: Documents from which test cases are derived.
8. Identify the accurate statement about Concepts:
- A. Verification asks 'are we building the product right'; validation asks 'are we building the right product'.correct
- B. Fixing a defect in production costs the same as fixing it during requirements.
- C. Quality assurance and quality control are the same role by definition.
- D. Verification and validation are precisely identical activities.
Why: Verification checks conformance to spec; validation checks user needs.
9. "Author-led informal review of a work product" — in Concepts, this describes which of the following?
- A. Debugging.
- B. Test basis.
- C. Inspection.
- D. Walkthrough.correct

10. "Linking requirements to tests and defects" — in Concepts, this describes which of the following?
- A. Dynamic testing.
- B. Debugging.
- C. Walkthrough.
- D. Traceability.correct
Why: traceability: Linking requirements to tests and defects.
11. In Concepts, which of the following is described as: "Developer activity of locating and fixing defect causes"?
- A. Debugging.correct
- B. Walkthrough.
- C. Dynamic testing.
- D. Test basis.
Why: debugging: Developer activity of locating and fixing defect causes.
12. Which Concepts concept matches this description: "Tool-based examination of code without executing it"?
- A. Inspection.
- B. Error, defect, failure.
- C. Traceability.
- D. Static analysis.correct
Why: static analysis: Tool-based examination of code without executing it.
13. In the context of Concepts, which of the following is a correct statement?
- A. Absence-of-errors fallacy: a defect-free system can still fail user needs.correct
- B. Static testing requires executing the compiled application.
- C. Verification and validation are precisely identical activities.
- D. Passing all tests proves the software contains zero defects.
Why: Meeting spec is worthless if the spec misses user expectations.
