What is the primary goal of interface/integration testing?

The primary goal of interface/integration testing is to evaluate how the system interacts with other systems. This type of testing focuses on the communication and data exchange between integrated components or systems to ensure they function together as intended. During integration testing, testers verify that integrated components work correctly as a unified system, identifying any issues that arise when different systems or modules interact. This is crucial for maintaining system integrity and ensuring that data flows seamlessly between different applications or services.

The focus is not primarily on confirming business requirements, which would be more aligned with requirements or functional testing. While data input is an important aspect of numerous testing phases, interface testing specifically assesses interactions, not just the input of data. Lastly, user satisfaction pertains more to usability testing, which centers on the end-user experience rather than the technical interactions being assessed during interface/integration testing.
