TS Quality Assurance Methods 2 — Questions and Answers
Question 1: Which QA activity is best described as a structured walkthrough led by the author of a work product?
- Inspection
- Walkthrough (Correct answer)
- Technical review
- Audit
Correct answer: Walkthrough
A walkthrough is led by the author to gather feedback, unlike an inspection which is led by a trained moderator.
Question 2: In root cause analysis, which technique uses a diagram to categorize potential causes of a defect into branches such as People, Process, Tools, and Environment?
- Pareto chart
- Scatter diagram
- Fishbone diagram (Correct answer)
- Control chart
Correct answer: Fishbone diagram
The fishbone (Ishikawa) diagram organizes potential causes into categories to identify the root cause of a problem.
Question 3: What does the 'shift-left' approach in QA primarily advocate?
- Moving testing activities earlier in the development lifecycle (Correct answer)
- Reducing the number of test cases
- Prioritizing left-side menu navigation testing
- Delegating testing to offshore teams
Correct answer: Moving testing activities earlier in the development lifecycle
Shift-left means introducing testing and quality activities earlier in the SDLC to detect defects sooner and reduce cost.
Question 4: Which metric measures the percentage of requirements that have at least one corresponding test case?
- Defect density
- Test coverage
- Requirements traceability coverage (Correct answer)
- Pass rate
Correct answer: Requirements traceability coverage
Requirements traceability coverage tracks how many requirements are linked to test cases, ensuring all requirements are tested.
Question 5: A QA team notices the same defect type recurring across multiple releases. What is the MOST appropriate next step?
- Increase the number of regression tests
- Perform a process improvement analysis to address the root cause (Correct answer)
- Log more defects in the defect tracker
- Escalate to the project manager immediately
Correct answer: Perform a process improvement analysis to address the root cause
Recurring defects indicate a systemic process issue that requires root cause analysis and process improvement, not just more testing.
Question 6: Which of the following BEST describes the purpose of a QA audit?
- Executing test cases against the software
- Reviewing and evaluating processes to ensure compliance with standards (Correct answer)
- Documenting defects found during testing
- Validating end-user acceptance criteria
Correct answer: Reviewing and evaluating processes to ensure compliance with standards
A QA audit examines whether processes conform to defined standards and procedures, not the product itself.
Question 7: In the context of QA, what is 'gold plating'?
- Adding extra features or quality beyond what the customer requested (Correct answer)
- Using expensive testing tools
- Applying premium coding standards
- Conducting extra rounds of regression testing
Correct answer: Adding extra features or quality beyond what the customer requested
Gold plating refers to adding features or enhancements beyond the agreed scope, which can introduce unnecessary risk and cost.
