A team has automated their regression tests, but the suite has become flaky—tests sometimes fail due to timing issues and environment problems. The team is spending too much time investigating false failures. What is the most effective way to address this?

Analyze the flaky tests, fix the root causes (e.g., synchronization, test data), and improve test isolation.

Increase the timeout values for all tests to reduce timing-related flakiness.

Disable the flaky tests to keep the suite green.

Run the suite multiple times and only report failures that occur consistently.

A team is about to change the database schema, which affects data access layers and reporting features. The regression suite includes tests for the data layer, reporting, and other modules. What is the best way to determine the regression test scope?

Use impact analysis to identify tests that exercise the changed schema and related features.

Run only the tests for the reporting features.

Run all tests because the schema change could affect everything.

Run only the tests for the data access layer.

A team has automated their regression tests, but the tests are not reliable because they depend on external services that are sometimes unavailable. This causes false failures. What is the best way to improve reliability?

Run the tests only when the external services are known to be available.

Mock or virtualize the external services in the tests.

Increase the timeout for tests that call external services.

Remove the tests that depend on external services.

What is the primary goal of regression test selection in an Agile context?

To replace manual tests with automated ones

To maximize the chance of detecting regressions while minimizing test execution time

To reduce the number of tests in the suite permanently

To ensure all tests are executed in every iteration

Part of the Test Strategy and Test Approach Challenges domain, which makes up ~20% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 2–3 from this objective — we provide 27 practice questions to prepare you well beyond it.
