Hi guys,

I'm pleased to say that JustMock is the only mocking framework I've actually got to work with Win8 Store/"Metro" projects

However, whenever there is a problem, instead of a detailed error I get:
Test method Win8Proto.Tests.WhenUserIsNotAuthenticated.ThenTryParseOAuthCallbackUrlIsCalled threw exception: <br>System.Resources.MissingManifestResourceException:
Unable to load resources for resource file "Telerik.JustMock.Messages" in package "97A458C7-A0AA-4BC7-B8FA-D9F82394A7BE".<

and so on. It doesn't matter what the error actually is

I've got the sample Just Mock projects working fine, and I can generally debug to work out what the actual problem/test failure is

what do you reckon?

Hi Toby,

It's great to hear that you’ve got JustMock running in your Windows 8 projects. However in order to let us investigate the missing manifest issue, I would request you to send us a copy of your project.

 

Kind Regards

Hi there,

I've created a new project, with the same test code in both Desktop and Store. In it, I'm mocking the System.Net.Http.HttpClient object and it's GetByteArrayAsync method. 

As I hope you can see, the Desktop one runs fine, but the Store version fails on 
httpClient.Arrange(client => client.GetByteArrayAsync(Arg.AnyString)).Returns(GetByteArray());


with the error:
Unable to load resources for resource file "Telerik.JustMock.Messages" in package "b56f7b53-edda-4fa2-89a4-214c7a0bc58b".


As far as I can see, the code is identical in both, except for one is a Windows Store app. I was really hoping that the Desktop version would fail with a useful error, but it wasn't to be ...

ah - can't attach the zipped project - where can I send it please?

ok, here's the test class - it works fine in Desktop unit test, but not Windows Store

[TestClass]
public class StoreUnitTests
{
    protected byte[] _response;
 
    private async void Act()
    {
        HttpClient httpClient = Mock.Create<HttpClient>();
        httpClient.Arrange(client => client.GetByteArrayAsync(Arg.AnyString)).Returns(GetByteArray());
        _response = await httpClient.GetByteArrayAsync("url");
    }
 
    [TestMethod]
    public void TestMockHttp()
    {
        Act();
        new ManualResetEvent(false).WaitOne(1000);
        Assert.IsNotNull(_response);
    }
 
 
    public Task<byte[]> GetByteArray()
    {
        return Task.Run(()
                        =>
                            {
                                var encoding = new UTF8Encoding();
                                return encoding.GetBytes("hello world");
                            }
            );
    }
}

Hi Toby,

Thanks again for contacting us.

If you are using portable library then elevated or commercial feature is not yet officially supported. However, you will still be able to mock interfaces and virtual members or in other words use JustMock lite features.

We are however working on this and keep you posted once we are ready.

Kind Regards

cheers Ricky,

JustMock is the only mocking framework I've got to run on WinRT, so I'm happy with what I've got!

I pushed the HttpClient down into a implementation of an interface that handles all the relevant operations and mocked that instead - it's not what I've got used to using JustMock on Desktop, but that only makes me appreciate that more, and there's always a way around

look forward to seeing the update, good luck because the work involved looks horrendous!
