Risk-Based Testing Quiz
How do you calculate risk in risk-based testing?
Risk = Impact + Probability
Risk = Probability × Impact
Risk = (Probability + Impact) / 2
Risk = Impact - Probability
A feature has Probability=4 and Impact=5. What is the risk score and level?
What test coverage is recommended for CRITICAL risk items (score 20-25)?
50% requirements coverage
70% requirements coverage
100% requirements coverage with extensive manual testing
Automation only, no manual testing
When should you re-evaluate risk assessments?
Continuously throughout the project when changes occur
Only after production incidents
Which factor is NOT typically considered in technical risk assessment?
Team member vacation schedules
For a LOW risk item (score 1-5), what is the recommended testing approach?
100% coverage with manual testing
50% coverage with automation only
90% coverage with exploratory testing
What should be the priority 1 in regression testing?
Critical user journeys and payment flows
How should testing resources be allocated based on risk?
All testers work on all risks equally
Senior testers on critical/high risk, junior on low risk
Junior testers on critical items for learning
What is a key benefit of risk-based testing?
Reduces testing time to zero
Optimizes testing resources by focusing on high-impact areas
Makes testing unnecessary
Which statement about risk mitigation is correct?
Risk mitigation is only needed for low-risk items
Once risk is assessed, no further action is needed
High-risk items need preventive actions, extended testing, and monitoring
Risk mitigation means avoiding all testing

Key Risk-Based Testing Concepts
Risk = Probability (1-5) × Impact (1-5)
Risk Levels:
- Critical: 20-25
- High: 12-19
- Medium: 6-11
- Low: 1-5
Test Coverage by Risk
Critical (20-25): 100% coverage + manual + security
High (12-19): 90% coverage + automation
Medium (6-11): 70% coverage + automation
Low (1-5): 50% coverage + automation only
Resource Allocation
Critical/High Risk → Senior Testers
Medium Risk → Mid-Level Testers
Low Risk → Junior Testers + Automation
