ISTQB Risk-Based Testing Strategies 5

Question 1

According to ISTQB, which of the following BEST describes the relationship between risk level and test depth?

Accepted Answer

Higher risk warrants deeper, more thorough testing to reduce residual risk

Answer

ISTQB risk-based testing principles state that higher-risk items should receive more intensive testing — more test cases, more rigorous techniques, and earlier execution.

Question 2

A tester is applying risk-based testing and runs out of time before completing all planned tests. Which outcome is MOST likely compared to a non-risk-based approach?

Accepted Answer

The most important areas have been tested first, so the untested areas pose lower risk

Answer

By executing the highest-risk tests first, a risk-based approach ensures that if time is cut short, the remaining untested areas are lower risk and the most critical potential failures have been addressed.

Question 3

Which of the following is a valid input to the risk assessment process?

Accepted Answer

Defect density metrics from previous similar projects

Answer

Historical defect data from similar projects is a valuable input to risk assessment, as it informs the likelihood that similar components or patterns will produce defects again.

Question 4

In ISTQB's risk-based approach, what is the role of 'risk monitoring' during test execution?

Accepted Answer

To track whether risk levels change as testing progresses and defects are found or mitigated

Answer

Risk monitoring during test execution involves tracking changes in risk levels as defects are found and fixed, or as new risks emerge, so that priorities can be adjusted accordingly.

Question 5

Which ISTQB testing level is MOST commonly associated with product risk assessment targeting business-critical functionality?

Accepted Answer

Acceptance testing

Answer

Acceptance testing, particularly user acceptance testing (UAT), is most closely associated with business-level product risk assessment since it validates the system against business needs and user expectations.
