ISTQB Certified Tester Foundation Level (CTFL 2018) — Question 17

After a record of poor quality software releases (incorrect menu selection options, new features that do not work, users allowed to change security levels without administrator rights), you have been asked to review the test capability in your company.
You have limited time to do the review before the next project, which type of testing would be MOST appropriate to review first?

Answer options

• A. Functional testing.
• B. Non-functional testing.
• C. Performance testing.
• D. Structural testing.

Correct answer: A

Explanation

Functional testing is crucial to ensure that all features work as intended and that user interactions are valid. Given the documented issues with incorrect options and features not functioning, addressing functional testing first will help rectify these critical problems. Non-functional, performance, and structural testing, while important, do not directly address the immediate concerns of functionality.
