// This class is a parent class for tests on QueueMap.
// It offers functions to work with a QueueMap test object which is built using types having only the minimal type requirements.
// Furthermore, the class checks that there are no memory leaks left after destructing the QueueMap (by counting leftover instances of Keys/Values).
