The description of the invention relates to a process for performing tests by means of which functionality and the real-time behavior of objects derived from concurrent classes can be tested. The particular advantage of the process according to the invention is that it is not individual objects that are instrumented for test purposes, but rather that the operating system is instrumented for test purposes. Furthermore, one major advantage lies in the fact that allocation information of source code to object code is used during testing which provides the programmer with a simple means of inputting test scenarios.

Process for performing at least one test on at least one of the objects of an object-oriented program capable of running in parallel on a computer

Method for testing at least one class of an object-oriented program on a

A method for integration testing of all objects of an object-oriented program in which an analysis of its source code is first carried out in order to identify the mutual dependencies between objects and classes and, on the basis of these dependencies, those objects that have already been tested are allocated to a set of tested objects and, further, objects that are dependent only on these tested objects are also identified. These objects are tested and are subsequently added to the set of tested objects. When no object can be found that is dependent only on tested objects, those objects are sought that are dependent only on one additional, untested object. This untested object can then be replaced by an object stub for test purposes. The object thus tested is subsequently transferred into the set of tested objects. When objects are found that are dependent only on one another and form a cycle, then one of these is replaced by an object stub in order to be able to test the other. As a result, all objects of the object-oriented program to be tested are united in the set of tested objects and the entire program is tested.
