What is the primary goal of refactoring test code to remove test smells?

To reduce the number of test cases in the suite

To eliminate the need for test documentation

To improve the maintainability and effectiveness of the tests

Which refactoring strategy is most appropriate for addressing an Eager Test that verifies multiple behaviors?

Split the test into multiple test methods, each focusing on a single behavior

Add more assertions to the test to cover all behaviors

Remove the test entirely because it is too complex

Combine the test with another test that has similar setup

A team is planning to refactor a legacy test suite. They want to identify which tests have the 'Mystery Guest' smell. Which approach would be most effective?

Counting the number of assertions in each test.

Running the tests with a profiler to measure execution time.

Reviewing the test code for external dependencies that are not obvious from the test itself.

Checking the test names for clarity and descriptiveness.

How do test smells primarily affect the ability of a test suite to detect defects?

They make tests more likely to pass even when the system is broken

They reduce the clarity of test failures and make it harder to identify the root cause of a defect

They make tests run slower, which reduces the number of tests that can be executed

They cause tests to fail randomly due to timing issues

Part of the Agile Approaches and Test Techniques domain, which makes up ~17% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~6–10 in this domain), expect 2–3 from this objective — we provide 24 practice questions to prepare you well beyond it.
