Error Mocking SPContentTypeCollection

[Andreas]

Hello together

I'm just trying to mock the SPContentTypeCollection class out of the SharePoint 2010 assembly but I'm facing a problem arranging a mock for the "BestMatch" method. I've already searched for a solution but cannot find any information about it.

This is my testcode:

SPContentTypeCollection mockedContentTypeCollection = Mock.Create<SPContentTypeCollection>();
Mock.Arrange(() => mockedList.ContentTypes).Returns(mockedContentTypeCollection);

SPContentTypeId mockedContentTypeId = Mock.Create<SPContentTypeId>();
Mock.Arrange(() => mockedContentTypeCollection.BestMatch(Arg.IsAny<SPContentTypeId>())).Returns(mockedContentTypeId).MustBeCalled();

The first three lines work perfectly, but an error is thrown for the fourth line. The mockedList is being creatd within a "TestInitialize" method.

This ist the call stack for the error occuring:

Test method XX.XX.Data.Tests.Repositories.XXRepositoryTests.AddPaymentSucceedsTest threw exception:
System.NullReferenceException: Object reference not set to an instance of an object.

Has someone face the same problem already and / or can someone help me finding a solution?

Thanks

Hi Andreas,

Thanks again for reporting the issue. Unfortunately, this is a bug in processing the SPContentTypeId argument that is throwing the exception. I am entering a task into our system which you can track here. 

http://www.telerik.com/support/pits.aspx#/public/justmock/10404 

However, I managed to find a solution for it as well and if you need it urgently then please open a support ticket where i will send the latest internal build that should resolve it.

Kind Regards,
