Exception trying to mock SharePoint 2010 UserProfileManager with JustMock

Question

I'm trying to create a mock version of UserProfileManager in order to effectively unit test a Sharepoint 2010 Web Part Every time I run this code, I get the the exception being thrown below. I've verified that the feature works when I debug the code that calls UserProfileManager on the Sharepoint machine - two different Sharepoint machines, in fact. Here is the code in question:

var _mockServiceContext = Mock.Create<SPServiceContext>();
var _mockUserProfileManager = Mock.Create<UserProfileManager>(new object[] {_mockServiceContext});

Unable to create instance of class SharePoint.MyWebPartTest. Error: Microsoft.SharePoint.SPException: The trial period for this product has expired..

Has anyone else seen this issuue?

Full disclosure: I'm a developer on the JustMock team.

When you call the Mock.Create<T>(object[] args) overload, you essentially say that you want a loose mock but you still want the constructor of the mocked type to run. From the stack trace I see that it is in fact that constructor that throws the exception. Is that what you actually want? Because that's rarely useful.

If you need a true loose mock it is best that you bypass its constructor. Basically, use the Mock.Create<T>() overload, like so:

var _mockUserProfileManager = Mock.Create<UserProfileManager>();
