The test scenario described to determine if admissions, discharge, and transfer will integrate with documentation and lab reporting modules is an example of:

• A. Unit testing
• B. Acceptance testing
• C. Integration testing
• D. System Testing

Answer: (C)

Testing how different modules exchange data and work together is what integration testing focuses on. In this scenario, the emphasis is on how admissions, discharge, and transfer (ADT) information flows to other parts of the system—specifically documentation and lab reporting modules. Integration testing checks that interfaces between these modules behave correctly, that data such as patient demographics, status changes, orders, and lab results are accurately exchanged, and that timing and data mappings (for example, HL7 messages or other interfaces) preserve meaning across modules.

Understanding why this is the right focus helps differentiate it from other testing levels. Unit testing looks at individual components in isolation, ensuring each piece functions by itself. System testing evaluates the entire system’s behavior as a whole against requirements, but not necessarily the interactions between distinct modules. Acceptance testing concentrates on meeting user and business needs in real-world usage.

So the described scenario best matches integration testing because it centers on verifying that separate modules work together correctly and share data seamlessly.
