1) Why do people say that APIs are not a user interface? APIs are at least THREE user interfaces at once. One user is the application program that "uses" the interface (that's a metaphor); two others are developers who call that interface for application services or for testing.
2) I believe thinking of "the user" is terribly limiting both for development and testing. Many people, with different goals and purposes and temperaments and skills and experiences, use our products. Our designs and testing could reflect that, if we bothered to remember it.
3) Even for APIs, it helps to consider a variety of developer- and tester-users. Some will be experienced, practiced; others may be novices. Some have tacit knowledge; none are mind readers. Build APIs and test them anticipating different people, and trouble for some of them.
