A method is described and represented for testing a control apparatus with a test device, where the control apparatus has at least one state variable and at least one actual functionality that contains a time dependency, and the control apparatus and the test device are connected to each other via a signal interface.The problem of the present invention is to prevent—at least partially—the disadvantages known from the state of the art, and, particularly, to provide a method for testing a control apparatus, which allows as simple and flexible an acquisition of the target functionality of a control apparatus is possible, and which takes into account the time dependency of the target functionality as comprehensively as possible during the test case generation.
