Used the create unit tests tool in Visual Studio and obviously it tries to instantiate my abstract classes.
My question is: Should I try to unit test the way Visual Studio is trying to get me to do it, or should I create a mock class to be instantiated, or should I only test the methods that use this abstract class?
Thanks.

Summary. There are two ways to unit test a class hierarchy and an abstract class: Using a test class per each production class. Using a test class per concrete production class.
You can not test whole abstract class. In this case you have abstract methods, this mean that they should be implemented by class that extend given abstract class.
There are two options to test an abstract base class (ABC) in Python: you can either override or patch the __abstractmethods__ property to be able to instantiate the abstract class and test it directly or you can create a child class that implements all the abstract methods of the base class.
mock() method for mocking the abstract classes. Using PowerMock instead of Mockito. mock() is a better approach as it can have control over the private as well as static methods. Step1: Create an abstract class named Abstract_class that contains both abstract and non-abstract methods.
If there are methods on this abstract class that are worth testing, then you should test them. You could always subclass the abstract class for the test (and name it like MyAbstractClassTesting) and test this new concrete class.
