ISTQB Risk-Based Testing Strategies 3

Question 1

In risk-based testing, 'risk mitigation' through testing means:

Accepted Answer

Reducing risk likelihood or impact by finding and fixing defects

Answer

Testing mitigates risk by detecting defects early; fixing those defects reduces the likelihood or impact of failures occurring in production.

Question 2

Which factor is LEAST relevant when assessing the likelihood of a software risk?

Accepted Answer

Color scheme chosen for the user interface

Answer

UI color scheme has no bearing on the likelihood of a functional or technical risk materializing; complexity, developer experience, and usage frequency all influence likelihood.

Question 3

A test manager is asked to cut 30% of the test suite due to schedule pressure. How should a risk-based approach guide this decision?

Accepted Answer

Remove tests covering the lowest-risk areas to preserve coverage of critical functionality

Answer

Risk-based testing calls for deprioritizing or removing tests on lower-risk areas first, ensuring the remaining effort is concentrated where failures would be most harmful.

Question 4

What does 'residual risk' mean after testing is completed?

Accepted Answer

The risk that remains after testing and mitigation activities have been applied

Answer

Residual risk is the level of risk that persists after all planned testing and other mitigations have been performed; it is typically accepted by stakeholders before release.

Question 5

Which ISTQB document or artifact formally records the risk-based testing approach and how risks influence the testing strategy?

Accepted Answer

Test plan

Answer

The test plan includes the risk-based testing approach, identifying how product risks drive test scope, priorities, effort allocation, and exit criteria.
