The tester checks whether the objects to be compared are instances of a class that implements the Java Map interface. This includes the HashMap and TreeMap classes in the Java Collections Framework.

For these objects the tester uses the Map methods to determine whether the two maps are of the same size, validates that they define the same key sets, and then validates that for each key-value pair in the first map there exists a matching key-value pair in the second map.
