Actually, this ExtendMethods.ConvertMap is an additional help for the user. If the user has a unknown type ar runtine, he van use this one to convert it. However, in the use cases of the bridge this will not happen from the user point of view (In the .Net Bridge, this is used very often). This test case is mainly for the test coverage. The method that the User uses ist:
ExtendMethods.ConvertMap<String, int>(Test); or ExtendMethods.ConvertMap<Entry1>(Test);
