I have this code in my SUT:

            FarmLoggingService tempService = FarmLoggingService.Local;
            if (null != tempService)
            {
                tempService.Update();
            }
            else
            {
                tempService = new FarmLoggingService();
                tempService.Update();

                if (tempService.Status != SPObjectStatus.Online)
                    tempService.Provision();
            }

I'm trying to figure out how to mock the call to the FarmLoggingService constructor: tempService = new FarmLoggingService.

I've tried variations all similar to 
     Mock.Arrange( () => new FarmLoggingService() ).Returns(mockSvc);  

where mockSvc was created  like this: 
     var mockSvc = Mock.Create<FarmLoggingService>(Constructor.Mocked);

But nothing seems to be working.  Ultimately, I need to be able to check that Update and Provision were each called once.  I have it working to return null from FarmLoggingService.Local to force me into the else block, mock the return value from the Status property so it always calls Provision, but I can't get the constructor bit working right.

Any ideas?

Thanks,

Dave

Hello David,

The way you're using the JustMock API is exactly correct. Mocking the return value of "new" expressions was a feature implemented in JustMock 2014 Q3. In fact, using the "Make object ID" feature of the Visual Studio debugger, you should be able to see that the mockSvc and the result of the "new" call are exactly the same instance.

Can you send me a repro project or a snippet with all the relevant code that demonstrates the issue?

Thanks, Stefan.  I'm using an older version of JustMock, so that must be why it didn't work.  Good to know I had it right, though.

Hi David,

Try it with the the 2014 Q3 version and see if you have any problems.
