Why is it important to verify a performance test script before running a full load test?

To ensure the script executes correctly and produces valid results

To eliminate the need for assertions

To reduce the test execution time

To increase the number of virtual users

What is parameterization in performance test scripting?

Adding comments to the script for better readability

Increasing the number of virtual users in the test

Capturing dynamic values from server responses

Replacing fixed values with variable data to simulate realistic user behavior

Why is error handling important in performance test scripts?

To increase the throughput of the test

To reduce the number of virtual users

To manage unexpected responses or failures gracefully

In a typical performance test, as concurrency increases from low to moderate levels, what is the expected effect on throughput?

Throughput increases until the system reaches a saturation point

Throughput becomes unpredictable and random

Throughput decreases proportionally

A performance test engineer is validating a script for a web service that returns XML responses. The script needs to verify that the response contains a specific element with a certain value. The engineer also wants to ensure that if the validation fails, the script logs the failure but continues running. Which combination of features should the engineer use?

Add a parameterization step to replace the XML element value with a variable.

Add a correlation step to extract the XML element value and use it in a subsequent request.

Add an assertion to check the XML element value, and configure error handling to log the failure and continue.

Add a think time after the request to allow the server to process the response.

Part of the Performance Testing Tasks 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 34 practice questions to prepare you well beyond it.
