Thank you for contacting Telerik support.
As far as I can understand, you want to use JustMock`s "Future Mocking" feature, which is shown here (please correct me if I have misunderstood you):
Is it possible for you to send us an example or a sample solution about the issue you are experiencing, so we can investigate it further or understand it clearer.
Thank you for your cooperation in advance.
the Telerik team
