Which statement about system testing is true?

• A. System testing should include security testing and be structured and controlled
• B. System testing excludes security testing and is informal
• C. System testing is only performed after go-live
• D. Security testing is optional in system testing

Answer: (A)

System testing validates the entire, integrated system in a controlled environment to confirm it meets requirements and operates as expected. Including security testing in this phase is essential, especially in healthcare, where protecting patient data, enforcing proper access controls, and maintaining audit trails across the whole system are critical. A structured and controlled approach means using a formal test plan with defined test cases linked to requirements, a dedicated test environment, clear entry and exit criteria, and documented results with a formal defect-management process. This testing should occur before deployment to production, not after go-live, and security testing should not be optional or informal. In short, the statement reflects testing of the system as a whole with security as a core focus, carried out in a disciplined, pre-release manner.
