Which of the following is not typically tested as an interface during the software testing process?

The focus of the software testing process typically revolves around the various interfaces that users and systems interact with during application operation. User interfaces are tested to ensure usability and user experience, application programming interfaces (APIs) are assessed to validate their functionality and integration capabilities, and database interfaces are checked for proper data retrieval and manipulation.

Network interfaces, while they are crucial components of the software's operational environment, are not typically considered direct interfaces in the context of software testing. They are more about connectivity and interoperability between systems rather than an interface that is part of the application itself, which is why they are not a primary focus during traditional software testing processes.

Therefore, while network interfaces play a role in how applications communicate over a network, they do not directly fall under the typical categories of interface testing, making them the least prioritized in standard software testing protocols.
