Hi
I've just downloaded ncrunch and I've enabled it for a solution that builds correctly in VS.

NCrunch is reporting a load failure for each of the projects in the solution though, with this rather uninformative message:

System.Exception: An exception was thrown in the remote environment: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException: A token of the wrong type passed to a metadata function.

Hi,

This is an exception thrown by MSBuild when it tries to interpret the XML of your project file.

Has the project file been hand-coded or heavily customised? Which template was used in its creation? Do you experience this problem on a fresh new solution using one of the standard VS project templates?

They are all standard projects.
MVC 4, some standard class projects and a few MStest projects.
No project files have been modified.

I created a new console app and I had the same problem when I enabled ncrunch.

I've installed ncrunch on a different machine and the solution gets further. It doesn't fully load, but it doesn't have an exception next to each project either.
What could be wrong with the MSBuild/projects to make it do this?

I can send you a sample project file if you'd like?

Absolutely - this would be a huge help. Could you submit it through the contact form? https://www.ncrunch.net/support/contact.

It's now loading all the projects on a different computer, but I am still having no luck using the initial pc.
On the PC where it's working i'm having a different problem now. I'm using Autofixture and AutoMoq with Nunit. The tests run fine using the resharper runner or the testdriven.net runner. They are reporting problems (consistently failing the same tests, but the tests seem fairly randomly from what I can tell) with this message:

NCrunch was unable to locate this test during NUnit's execution run. This problem can be caused by tests with names that contain random elements, such as through the use of NUnit's RandomAttribute. Please ensure your test is named consistently or consider changing your 'Framework utilisation type for NUnit' solution-level configuration setting to 'StaticAnalysis'.

The odd thing about this is that I am using the same process elsewhere in the same project and the tests are reporting as pass or fail.

This one fails:

Code:

[TestFixture]
    public class ClientTests
    {
        [Test]
        [AutoMoqData]
        public void ClientStringifyReadsCorrectly(Client sut)
        {
            // Arrange

            // Act
            var result = sut.ToString();

            // Assert
            Assert.AreEqual("Client: " + sut.Name + ": " + sut.Id, result, "Result is in the wrong format");
        }
    }


while this one passes (in the same project)
Code:

[TestFixture]
    public class GetEventAnswersTests
    {
[Test, AutoMoqData]
        public void QuestionEvent_NoAnswer(
            QuestionEvent instanceEvent
            )
        {
            // Arrange
            instanceEvent.Answer = null;

            // Act
            var result = instanceEvent.GetAnswers();

            // Assert
            Assert.AreEqual(0, result.Count);
        }
...


The only difference that I can see is that one has only one test in the class while the other has multiple tests.
Actually, I turned the second example into a class with only one test and it still passes.

Any help on this? I'd really like to try your product!

PS I saw that there was another difference, that there were two lines of attributes on the failing test. I changed it into one
([Test, AutoMoqData]) and it didn't fix the issue.

The auto-mocking issue is likely to be caused by inconsistencies in the test name.

Because NCrunch needs to uniquely identify a test by its name (which in the instance of a testcase, is generated from its parameters), there is a known issue where having a test with a name that is inconsistent or randomly generated will cause the NCrunch to be unable to locate the test during the execution run.

There are two ways to solve this problem:

1. Avoid using arrangements where test names are not unique - likely this would mean not using automoq.
2. Set the 'framework utilisation type' for NUnit to StaticAnalysis (solution-level NCrunch configuration setting). It is unknown to me whether StaticAnalysis will work with automoq, as this depends upon how it is implementing its own internal logic. There is a strong possibility that StaticAnalysis will not work with automoq.
