A team has optimized their regression suite using AI-based test selection. They now run only 30% of the original tests. They want to evaluate whether the optimized suite still provides adequate fault detection. Which approach would best assess this?

Ask developers if they feel confident

Compare the fault detection rate of the optimized suite against the full suite on a set of known defects

Count the number of tests in the optimized suite

Measure the execution time of the optimized suite

What is the primary purpose of using AI techniques to optimize regression test suites?

To reduce the number of tests executed while maintaining high fault detection

To guarantee that all possible defects are found

To replace manual testing with automated testing

To eliminate the need for manual test design

A team has a regression suite with many tests that exercise the same code paths. They want to reduce the suite by removing redundant tests while keeping the same code coverage. Which AI technique is most appropriate?

Fault prediction-based selection

A team maintains a large regression suite for a banking application. The suite takes over 8 hours to run, and they need to reduce execution time while keeping the highest-risk areas well covered. They decide to use an AI technique that groups test cases based on the code modules they exercise and then selects a representative from each group. Which AI technique are they applying?

Fault prediction-based test selection

Risk-based test case prioritization

Clustering-based test suite reduction

Coverage-based test suite minimization

Part of the Domain 11: Using AI for Testing domain, which makes up ~11% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~3–4 in this domain), expect 1–1 from this objective — we provide 26 practice questions to prepare you well beyond it.
