HR Quality Control & Assurance 2 — Questions and Answers
Question 1: Which metric measures the percentage of defects found in testing versus defects found in production?
- Defect Escape Rate (Correct answer)
- Defect Density
- Mean Time to Repair
- Test Coverage Ratio
Correct answer: Defect Escape Rate
Defect Escape Rate tracks what percentage of total defects slipped past QA into production, indicating testing effectiveness.
Question 2: In HR software QA, what does regression testing primarily verify?
- New features work as specified
- Previously working features still function after code changes (Correct answer)
- Security vulnerabilities are patched
- Database schema migrations are correct
Correct answer: Previously working features still function after code changes
Regression testing ensures that recent code changes haven't broken existing, previously verified functionality in the HR system.
Question 3: A QA team discovers that payroll calculations produce different results on different servers. This is an example of which type of defect?
- Functional defect
- Performance defect
- Environment-dependent defect (Correct answer)
- Data integrity defect
Correct answer: Environment-dependent defect
Environment-dependent defects occur when software behaves inconsistently across servers, OS versions, or configuration settings.
Question 4: Which QA approach tests HR software APIs directly without going through the UI?
- End-to-end testing
- API testing (Correct answer)
- Acceptance testing
- Smoke testing
Correct answer: API testing
API testing validates the backend service contracts and data exchange of HR software independently of the front-end interface.
Question 5: When a QA engineer verifies that an employee can only view their own pay stubs and not others', they are performing which type of test?
- Performance testing
- Authorization testing (Correct answer)
- Load testing
- Smoke testing
Correct answer: Authorization testing
Authorization testing confirms that users can only access resources and data they are permitted to see, enforcing role-based access controls.
Question 6: What is the purpose of a QA traceability matrix in HR software development?
- Track developer productivity
- Link test cases to specific requirements (Correct answer)
- Monitor server uptime
- Log defect resolution time
Correct answer: Link test cases to specific requirements
A traceability matrix maps test cases to requirements, ensuring every requirement is tested and no functionality is overlooked.
Question 7: Which testing type would catch a bug where the HR system crashes when 5,000 employees simultaneously request PTO approvals?
- Unit testing
- Load testing (Correct answer)
- Boundary testing
- Sanity testing
Correct answer: Load testing
Load testing simulates high user concurrency to identify performance bottlenecks and system breaking points under heavy traffic.
