What is the aim of interface testing?

The aim of interface testing is to verify that the system correctly interfaces with other systems and components. This type of testing evaluates the interactions between different software components, applications, or systems to ensure they communicate and function together as intended. It involves checking data exchanges, error handling, and the proper implementation of protocols, ensuring that when one component sends data to another, the receiving component processes that data accurately. It confirms that different modules or subsystems work together seamlessly, which is crucial for overall system integrity and functionality.

Ensuring visual appeal of components addresses user interface design rather than interface testing, making it less relevant in this context. User-friendliness also focuses more on usability rather than the correctness of the interface interactions. Measuring the speed of data processing is unrelated to interface validation, as it pertains more to performance testing than to verifying how systems interact with each other.
