Which characteristic of software testing involves evaluating how well a program interacts with other systems?

Usability
Testability
Interoperability
Portability

The correct answer is: Interoperability

Interoperability is the characteristic of software testing that specifically focuses on evaluating how well a program interacts with other systems. This includes assessing the ability of different software applications, systems, or components to work together effectively. In the context of software testing, interoperability ensures that the software can exchange and make use of information with external systems, which is crucial for software that needs to function in a connected environment or as part of a larger ecosystem. In contrast, usability pertains to how user-friendly and intuitive a software application is for its intended users, emphasizing user experience rather than system interactions. Testability refers to the ease with which the software can be tested, highlighting aspects such as the availability of good test cases and the simplicity of the software's architecture. Portability concerns whether the software can be easily transferred from one environment to another, such as moving from development to production, without issues. Thus, while these other characteristics are important in their own right, they do not specifically address the interaction between different systems like interoperability does.
