Thanks for bringing up the question. Yes you can mock members from abstract base class. Here i have created an abstract class :
For that i simulated the following test that worked as expected:
var foo = Mock.Create<FooBase>();
Mock.Arrange(() => foo.Submit()).DoInstead(() => called =
It is also possible to mock virtual members from abstract base class if it is implemented in another class that is used as the target.
Hope this information is useful.
