ISTQB Certified Tester Advanced Level – Test Analyst (CTAL-TA) — Question 45

Rather than developing an e-commerce product, management has decided to acquire a COTS package. The e-commerce product needs to interface with backend applications such a Finance, stock control and order delivery. You are asked to define a test plan for this project.

Given just the information in the scenario, which of the following software quality characteristics must be included in your test plan? (Choose all that apply.)

Answer options

• A. Interoperability
• B. Reliability
• C. Maintainability
• D. Portability

Correct answer: A
