A reference model for an interface is provided by creating together with the interface a first and a second auxiliary program. The first auxiliary program (A") is a model program simulating use of the interface, and the second auxiliary program (B") is a model program simulating that it offers the functions in the interface. Both programs shall be able to execute all possible and admissible operations over the interface at the same time controlling that the other program does not make anything impermissible. |
