Cannot mock .... The profiler must be enabled to mock, arrange or execute the specified target

Question

I have the following in a test (my first ever JustMock test, I might add)...

        var template = Mock.Create<MessageType>();
        Mock.Arrange(() => template.Subject)
            .Returns("This template has Zero tokens.");

        Mock.Arrange(() => template.Body)
            .Returns("This template has {{number}} of {{tokens}}.");

The class being Mocked looks like this ...

public class MessageType : BaseBusinessEntity
{
    public string Body { get; set; }

    public int DigestsToBeIncludedOn { get; set; }

    public Guid MessageReference { get; set; }

    public int MessageTypeId { get; set; }

    public string Name { get; set; }

    public int PredefinedRecipients { get; set; }

    public string Subject { get; set; }
}

When I attempt to run the test I get ...

Error Message: Test method Genesis.Service.Implementation.Tests.DigestFixture.ShouldCorrectlyExtractTemplateTokens threw exception: Telerik.JustMock.Core.ElevatedMockingException: Cannot mock 'System.String get_Subject()'. The profiler must be enabled to mock, arrange or execute the specified target.

Can anyone point out what I've done wrong?

Answer 1

Be sure you have enabled the profiler from the menu.

While using Visual Studio for writing your tests you will notice the Telerik menu and the JustMock menu-item in it. Once there, you have to check if JustMock is enabled(“Enable JustMock” should be grey, see the example bellow).
