Unable to Mock SendResponse

[MrCodeB2]

Hi Luke! I tried to write a unit test for my Fluentmail implementation but i am unable to mock the SendResponse.Successful, since it is readonly and the class is not virtual/abstract.

If you try something like this:

Mock<SendResponse> sendResponseMock = new();
sendResponseMock.SetupGet(x => x.Successful).Returns(true);

I get a "non-overridable members" error

Do you have an idea?

best regards Konrad
