CAST - Risk-Based Testing Strategies Questions and Answers

Question 1

In a risk-based testing strategy, which two factors are primarily used to assess and prioritize risks?

Accepted Answer

Likelihood of failure and impact of failure

Answer

Risk-based testing prioritizes testing efforts based on the potential risk of failure and the impact that failure would have on the business or users. The combination of likelihood (probability) and impact (severity) determines the overall risk level, guiding the test strategy.

Question 2

A project team is developing a new e-commerce application. They have limited time for testing before the scheduled launch. Using a risk-based approach, which module should receive the HIGHEST priority for testing?

Accepted Answer

The payment processing and checkout gateway

Answer

The payment processing and checkout gateway represents the highest risk. A failure in this area would have a direct and severe financial impact on the business and would critically affect the user's primary goal. While other features are important, a failure in payment processing is the most impactful potential failure.

Question 3

Which of the following is the primary goal of implementing a risk-based testing strategy?

Accepted Answer

To optimize testing efforts by focusing on the most critical areas.

Answer

The fundamental purpose of risk-based testing is not to test everything exhaustively, but to allocate limited testing resources (time, people, budget) to the parts of the application that pose the greatest risk to the project's success. This ensures that the most critical potential issues are addressed first.

Question 4

During the risk identification phase of risk-based testing, which activity is LEAST likely to be performed?

Accepted Answer

Writing and executing all high-priority test cases.

Answer

Writing and executing test cases is part of the test execution phase, which happens *after* risks have been identified, analyzed, and a test plan has been created. The risk identification phase focuses on discovering potential problems through activities like meetings, data analysis, and requirements review.

Question 5

A feature is identified as having a high probability of failure but a very low business impact if it fails. According to a typical risk-based testing strategy, how should testing for this feature be prioritized?

Accepted Answer

It should be prioritized lower than high-impact features.

Answer

In risk-based testing, the impact of a failure is a critical component of prioritization. Even if a failure is likely, if its impact is negligible, it represents a lower overall risk than a feature with a lower probability of failure but a critical impact. Therefore, it should be prioritized below high-impact items.
