Certified Information Systems Auditor (CISA) — Question 1361

Which of the following is the BEST way to ensure that an application is performing according to its specifications?

Answer options

• A. Pilot testing
• B. System testing
• C. Integration testing
• D. Unit testing

Correct answer: B

Explanation

System testing is the most comprehensive method to evaluate an application against its specifications, as it tests the entire system as a whole in a production-like environment. Pilot testing, integration testing, and unit testing focus on specific components or stages, and may not capture the overall performance and compliance with specifications.
