What is a typical outcome of designing test scenarios?

• A. Eliminate the need for end-user testing.
• B. Increase testing coverage and realism.
• C. Remove the requirement for scripts.
• D. Guarantee defect-free software.

Answer: (B)

Designing test scenarios focuses on representing how users actually interact with the system. By weaving together typical tasks into end-to-end flows, you broaden testing coverage and add realism, capturing how different parts of the system work together under real-world conditions. This helps reveal issues that isolated, single-step tests might miss and ensures the testing mirrors how the product will be used.

End-user testing (UAT) is still important because scenarios don’t replace user validation; they guide realistic testing, but real users must verify that the system meets needs in practice. Test scripts provide concrete steps and expected results for reproducibility, but scenarios describe the broader flows testers should exercise. And while testing can reduce risk and defects, it cannot guarantee a defect-free product.
