The informatics nurse specialist is developing a test scenario to determine if the admissions, discharge and transfer application will work with the clinical documentation and laboratory results reporting modules of a larger electronic health record. This is known as:

• A. Unit testing
• B. Integrated testing
• C. Acceptance testing
• D. System testing

Answer: (B)

Testing the ability of the admissions, discharge and transfer component to work with the clinical documentation and laboratory results reporting modules focuses on how separate parts of the system communicate and exchange data. This is integrated testing, which examines the interfaces and interoperability between modules within a larger system to ensure data flows correctly, formats align, and interactions function as intended. It differs from unit testing, which checks each module in isolation; system testing, which evaluates the entire system’s behavior as a whole; and acceptance testing, which verifies the system meets user and business requirements. So the scenario best fits integrated testing.
