Hi,


Since I upgraded my JustMock I was unable to debug ASP.NET projects. I accidentally found a resolution to the problem here:

http://stackoverflow.com/questions/19415275/asp-net-mvc4-code-not-running

"If you are using Telerik JustMock as a mocking framework and have recently updated it to the 2013 Q3 version, it causes this exact problem. I was able to resolve this issue by uninstalling the mocking framework and installing the 2013 Q2 version."

So I uninstalled JustMock and everything came to normal.


Regards,
Ovidiu

Creating a share link with Visual Studio Live Share does not work if you have the JustMock profiler enabled. We specifically have to disable the JustMock profiler in order for VS Live Share to create sharing links. This has been reproduced by several different members of our team.

Could this please be looked into? Thanks!

The debugger arrowhead pointer is not positioned to the correct execution line when debugging .Net Core. Stepping the code line by line advances the yellow arrowhead pointer based on the initial offset/messed position. When the arrowhead leaves the method the remaining lines are executed at once.

Having the following COM interop class

[ClassInterface(ClassInterfaceType.None)]
[Guid("86332C4E-0BDE-46EC-94C5-0A946C33C682")]
[TypeLibType(TypeLibTypeFlags.FCanCreate)]
public class MyComObjectClass : IMyComObject, MyComObject
{
    public MyComObjectClass();

    [DispId(1)]
    public virtual string Echo(string message);
}

and the sample class that uses it:

public class MyComObjectClassProxy
{
    public string Echo(string message)
    {
        IMyComObject itf = null;
        try
        {
            itf = new MyComObjectClass();
            return itf.Echo(message);
        }
        finally
        {
            if (itf != null)
            {
                Marshal.ReleaseComObject(itf);
            }
        }
    }
}

When I try to call the arranged constructor I am getting an error "Cannot create instances of type requiring managed activation", the unit test code:

[TestMethod]
public void TestMethod1()
{
    var mock = Mock.Create<MyComObjectClass>();
    Mock.Arrange(() => new MyComObjectClass()).Returns(mock);

    var sut = new MyComObjectClassProxy();
    var actual = sut.Echo("Message");

    Assert.AreEqual(string.Empty, actual);
}

My team and I have spotted some odd behaviour with the latest version of JustMock (2015.3.929.5) when targeting a Windows Store app.

If we create a mock for an object in a helper method, the mock fails when making assertions for calls to the mock.

The following code illustrates the issue:

        [TestMethod]
        public void ThisWillFail()
        {
            var subject = CreateSubject();

            subject.DoSomething();

            subject.Assert(s => s.DoSomething(), Occurs.Once());
        }

        [TestMethod]
        public void ThisWillPass()
        {
            var subject = Mock.Create<ISubject>();

            subject.DoSomething();

            subject.Assert(s => s.DoSomething(), Occurs.Once());
        }

        public interface ISubject
        {
            void DoSomething();
        }

        private static ISubject CreateSubject()
        {
            return Mock.Create<ISubject>();
        }

In this code, the first test will fail but the second test will pass. The only difference is that, in the first test, we're setting up the mock in a helper method.

We have a "Unit Test Library (.NET for Windows Store apps)" referencing the Telerik.JustMock assembly. I have attached a simple project containing this implementation.

It's worth noting that the same code passes in a regular .NET class library; it only fails in a "Unit Test Library (.NET for Windows Store apps)". It's also worth noting that this worked under an older version of the assembly (2014.3.1021.2).

Any help would be appreciated, as we currently have around 3,000 tests and a good proportion of them set up their mocks using a helper method in this way.

There is a different behaviour when mocking the same method using the following two Arrange overrides:

public static FuncExpectation<TResult> Arrange<TResult>(Expression<Func<TResult>> expression);
public static FuncExpectation<TResult> Arrange<T, TResult>(T obj, Func<T, TResult> func);

Repro project attached. Steps to reproduce:
1. Open attached solution
2. In Tests.cs, run JustMockArrangeQueryableTest - it passes
3. Run JustMockArrangeQueryableTest2 - it fails with a invalid cast exception on the Residents collection.

Tests fail when run with vstest.console.exe but pass when run from VS2015.

Findings: The problematic scenario includes reference to Microsoft.WindowsAzure.ServiceRuntime.dll and usage of the RoleEnvironment class. When the RoleEnvironment class is used in a test project without JustMock and runned from vstest.console the exception will be thrown as well. Here is the exact exception: 
System.TypeInitializationException: The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment' threw an exception. ---> System.TypeInitializationException: The type initializer for '<Module>' threw an exception. ---> <CrtImplementationDetails>.ModuleLoadException: The C++ module failed to load while attempting to initialize the default appdomain.

Workaround: the vstest.console.exe could be started with parameter /InIsolation, which runs the tests in an isolated process. Here is the link to the command line options: https://msdn.microsoft.com/en-us/library/jj155796.aspx

This appears to be related to the recent fix for "Improve exception message for Mock.Create".  Without Behavior.CallOriginal it works.  Supplying a parameter also works.

Visual Studio debugger arrowhead pointer is messed when profiler is enabled with .Net Core 2.1, in VS2107/2019

Steps

  • Use elevated features like static mocking using JustMock
  • Enable profiler from VS JustMock extension
  • Run the test in debug mode

Code Snippet

Mock.SetupStatic(typeof(ElasticOperationsHelper), Behavior.Strict, StaticConstructor.Mocked);

Mock.Arrange(() => elasticRepository.IndexDocumentInElastic<IndexDocText>(Arg.IsAny<IndexDocText>(), Arg.IsAny<string>(), null)).Returns(response);

 

While debugging it's found the arrowhead pointer of VS debugger is messed up and pointing to wrong line numbers. It's quite difficult to develop unit tests at this situation. Is there any resolution of this problem.

I found an article in the support page has been declined due to same problem. Is this totally dependent on "CLR" fix and .Net profiler. If so could you please provide me the Bug details of Microsoft for the same?

I would also like to know why it's necessary to have profiler enabled for scenarios like "Static Mocking", "Non virtual method mocking", "Private Mocking" etc. 

Is this only happening for .Net core? 

Hyland Software is evaluating this product as their Mocking framework for unit testing of all .net core projects.

If there is no solution, how can any prospective customer consider this as a good fit for their usage? If there is any workaround possible at this moment?

Basically calling Mock.Reset at the end of the method is not safe.
It seems like the the way JustMock iterates over an IEnumerable is not correct.

Types that implement ISerializable can't be mocked anymore with the 2019.1.115.2 version resulting in System.ArgumentException. The issue is a regression compared to older versions of JustMock.

A simple WinForms application crashes on start when JustMock(2019.1.115.2) profiler is enabled.

Steps to reproduce:
1. Create a new WinForms Application.
2. Start the application. In Debug it is most visible. 
3. After the application is started move the mouse in the middle of the application. The exact location is not important.
4. A FieldAccessExceptionis is thrown.

System.FieldAccessException: Attempt by method 'System.Windows.Forms.SafeNativeMethods._TrackMouseEvent(TRACKMOUSEEVENT)' to access field 'System.AccessibilityImprovements.useLegacyAccessibilityFeatures' failed.

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)


Temporary workaround: disable the JustMock Profiler from the JustMock menu while developing the application and enable it while running the tests.
A fix can be expected with the next official release. You can follow this item in order to receive status updates.

I just installed it onto desktop, loaded Visual Studio 2019 (Ent) and i see no visual reference or otherwise to JustMock.

Honestly If i had have spent the $$ by now i'd have uninstalled and given up.
