I'm trying to write some unit tests for a Sharepoint 2010 Webpart that uses UserProfile manager.
In order to mock UserProfileManager, I also need to mock SPServiceContext.

When I try to assign my mock variable, like this:

_mockServiceContext = Mock.Create<SPServiceContext>();

The following exception is thrown:

Type 'Telerik.JustMock.MockException' in assembly 'Telerik.JustMock, Version=2013.1.507.0, Culture=neutral, PublicKeyToken=721b6c5bc0326b3a' is not marked as serializable.

Any idea what I'm doing wrong?

Hi Nathanael,

Thank you for reporting this issue.

It appears this is a bug in JustMock 2013 Q1 SP2 which has already been fixed. The fix will be included in the upcoming release this month.

I hope this information helps.

P.S. For reporting this, we have granted you some Telerik points.

All the best,
Kaloyan

I've had a chance to use the latest version of JustMock, and the same original line of code throws the following exception: Type is not resolved for member 'Telerik.JustMock.Core.ElevatedMockingException,Telerik.JustMock, Version=2013.2.611.0, Culture=neutral, PublicKeyToken=721b6c5bc0326b3a'. Anything else I can try?

Hi Nathanael,

I checked this once again. The following example works as expected since JustMock Q2 release:
// Arrange
var expectedGUID = new Guid();
 
var _mockServiceContext = Mock.Create<SPServiceContext>();
Mock.Arrange(() => _mockServiceContext.SiteSubscriptionId).Returns(new SPSiteSubscriptionIdentifier(expectedGUID));
 
// Act
var actual = _mockServiceContext.SiteSubscriptionId;
 
// Assert
Assert.AreEqual(expectedGUID, actual.Id);

Please, make sure you have updated the JustMock references inside your project.


I hope this solves the issue.

Regards,

I just tried this again with a freshly installed Sharepoint 2010 VM.
Can you verify what version of Unity you're using to run a successful test? I'm not able to download the latest version for this test project because it's built for .NET 3.5

This is the error coming in now, with a fresh rebuild of a Sharepoint VM. Does JustMock Lite not support mocking Sharepoint?

Cannot mock 'Microsoft.SharePoint.SPServiceContext'. JustMock Lite can only mock interface members and virtual/abstract members in non-sealed classes on instances created with Mock.Create. For any other scenario you need to have the full version of JustMock.

Hi Nathanael,

This is exactly the case. As SPServiceContext is a sealed class, you will need the profiler in order to mock it. More about mocking sealed classes with JustMock can be found here.

Let me know if there is anything else I could help you with.

I'm now using the full version of JustMock with a trial license. I'm running this line:
_mockServiceContext = Mock.Create<SPServiceContext>();

and I'm getting the following error:

Hi Nathanael,

Please, make sure you have the JustMock profiler enabled when executing the test. To enable it, navigate to the JustMock menu inside Visual Studio.

If the above is not the case, please send us the event logs with ID 1022. To do this:
  1. Fail your test once again (just to be sure the correct event log will be sent);
  2. Open Event Viewer and navigate to Windows Logs -> Application;
  3. Copy the latest event logs with an ID 1022;
  4. Send them with your next reply.

You can also try and solve the issue by following the steps in this article.

I hope this helps. Please let me know with the results.

Thank you for the help. I was able to get past that step, and now I'm on to the next error. I'll start a new thread for that though, since it's not about SPServiceContext anymore :)
