A team has a regression suite of 1,500 tests. They want to select a subset of tests to run for each code change, using an AI model that predicts which tests are most likely to detect faults. They have historical data on test failures and code changes. What is the primary input to the AI model for this task?

Historical test results and code change metadata

The number of testers on the team

A company has a regression suite that has grown to 10,000 test cases, and nightly runs take over 10 hours. They are considering using AI to optimize the suite. What is the primary benefit they can expect from AI-based test suite optimization?

Elimination of all manual testing

Automatic generation of new test cases

Guaranteed detection of all defects

Reduced execution time while maintaining high fault detection

Which of the following is an example of an AI-driven prioritization strategy for regression tests?

Executing all tests in the order they were written

Using a machine learning model to rank tests by predicted defect probability

Running tests in alphabetical order by test name

Randomly shuffling test order before each run

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.
