ISTQB Certified Tester Advanced Level – Test Analyst (CTAL-TA) — Question 64

You work for an insurance company that is running several parallel projects. You have been asked to advise on the best approach for test case design for each project.
Project C has been experiencing quality issues with the requirements documentation. In previous releases, the requirements were perceived to be vague and inconsistent, prompting many time-consuming questions from the test analysts during analysis and design. For the current release, more formal requirements reviews have been introduced to try and improve quality.
Project D has recognised the need for better regression testing and it is expected that 80% of the test cases created in the next release will form part of the regression pack. The regression tests will be run manually with a plan to introduce automation for future releases.
What should your recommendation be with respect to the level of test case design for projects C and D?

Answer options

• A. Project C - High level test cases. Project D - High level test cases.
• B. Project C - High level test cases. Project D - Low level test cases.
• C. Project C - Low level test cases. Project D - High level test cases.
• D. Project C - Low level test cases. Project D - Low level test cases.

Correct answer: D

Explanation

The correct recommendation is to use low level test cases for both Projects C and D. For Project C, the previous issues with vague requirements necessitate detailed test cases to ensure clarity and thorough coverage. In Project D, given that most of the test cases will be part of a regression pack, low level test cases will provide the necessary depth for effective regression testing, despite the initial manual execution.
