Integrated testing is testing between systems. What is the purpose of integrated testing?

• A. Testing a single module
• B. Testing interactions between systems
• C. Testing user acceptance of the entire system
• D. Testing only hardware compatibility

Answer: (B)

Integrated testing focuses on how different systems interact at their interfaces, ensuring that data and control flow between components are correct and reliable. The goal is to validate that connected systems—such as an EHR, a laboratory system, and a billing system—exchange messages accurately, that data formats and mappings align, and that end-to-end workflows across integration points operate smoothly. This helps uncover interface defects, timing issues, and error-handling problems that wouldn’t appear when testing a single module in isolation. It’s distinct from testing a single module (unit testing), user acceptance testing (which looks at user needs and overall usability), and hardware compatibility testing (which checks software-hardware interactions).
