Mock Extension Method Throws "Object reference not set to an instance of an object."

[Erik]

I am simply trying to mock an extension method on an Enum and no matter how I set it up I always seem to get a "Object reference not set to an instance of an object." error. Here is my code:

var invalidType = new MyEnum();
Mock.Arrange(() => invalidType.ToType()).Returns((System.Type)null);

The extension method (ToType) is just a switch statement that maps enum values to Types. I also tried using a mock for the invalidType.

Hi Erik,

Thanks again for reporting the issue.

I was able to reproduce the problem and make the fix. Should you need a build urgently, please open a support ticket where I will send the updated version of Telerik.JustMock.dll that should solve your issue.

I also created a task which you can follow here:
