What is the primary purpose of analyzing test case effectiveness?

To increase the number of test cases regardless of value

To evaluate how well test cases detect defects and cover requirements

To replace manual testing with automated testing

To assign blame for failed test cases

What does identifying improvement opportunities from test case analysis primarily involve?

Collecting more data without any analysis

Deriving actionable insights to optimize test cases

A team analyzes test results and finds that 80% of defects are detected by only 20% of the test cases. What does this analysis suggest?

The test cases are evenly effective across the suite.

The test environment is causing most defects.

The team should immediately delete the 80% of test cases that find few defects.

A small subset of test cases is highly effective; the rest may be candidates for optimization.

Which factor is typically considered when prioritizing test case improvements?

The number of testers who like the test case

The effort required to implement the improvement

The date the test case was created

A team modifies test cases to improve defect detection. What is the most effective way to monitor whether the modification achieves the desired outcome?

Compare the number of test cases before and after the modification.

Ask the test team for subjective feedback on the changes.

Track the defect detection rate of the modified test cases over several releases.

Check if the modified test cases pass consistently.

Objective: Discover Opportunities for Improving Test Cases Through Data Collection and Analysis CTAL-TAE Practice Questions (Page 2)

Part of the Domain 8: Continuous Improvement domain, which makes up ~18% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~6–11 in this domain), expect 2–3 from this objective — we provide 24 practice questions to prepare you well beyond it.
