Abstract class unit test

[Ryan]

I'm evaluating JustMock and have some unit tests that I want to write against an abstract base class. I wish to test some functionality in the base class. Can JustMock create a concrete class in which I can test with or do I need to implement a derived class myself? I want the base class method called, I just would like to know if JustMock provides any support here.

Hi Ryan,

Thanks for bringing up the question. Yes you can mock members from abstract base class. Here i have created an abstract class :

public abstract class FooBase
{
    public abstract void Submit();
}

For that i simulated the following test that worked as expected:

var foo = Mock.Create<FooBase>();
bool called = false;
Mock.Arrange(() => foo.Submit()).DoInstead(() => called = true);
foo.Submit();
Assert.IsTrue(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.

Kind Regards,
