ISTQB Tool Support for Testing 5

Question 1

In the context of ISTQB, which factor most significantly determines whether a test tool will deliver expected benefits?

Accepted Answer

The degree to which the tool is adopted and used correctly within the organization

Answer

Tool success depends primarily on organizational adoption and correct usage; even the best tool delivers no value if improperly used or ignored.

Question 2

Which type of testing tool would be most appropriate for verifying that an application's API endpoints return correct HTTP status codes and response bodies?

Accepted Answer

API testing tool

Answer

API testing tools send requests directly to service endpoints and validate responses including status codes, headers, and body content without a UI.

Question 3

A test team notices that their automated test suite takes 4 hours to run. Which approach would best address this?

Accepted Answer

Parallelize test execution across multiple machines or containers

Answer

Parallel test execution distributes tests across multiple agents simultaneously, significantly reducing total execution time without reducing coverage.

Question 4

Which of the following best describes the role of a 'test oracle' in automated testing?

Accepted Answer

A mechanism that determines whether the actual test outcome matches the expected result

Answer

A test oracle is the mechanism — whether a rule, expected value, or reference system — used to decide if a test has passed or failed.

Question 5

According to ISTQB, what is a 'test stub'?

Accepted Answer

A simplified version of a called component used to isolate the unit under test

Answer

A stub replaces a called component (e.g., a downstream service) with a simplified implementation that returns predefined responses during testing.
