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.

The issue is reproducible inside Visual Studio 2017, the same tests are running normaly outside the IDE or using 2019.

The internal (non-public) events are not handled properly by JustMock, there is no indication for error, Raise arrangement simply does not working as expected. The following sample reproduces the issue:

namespace TestExample
{
    public class ClassWithEvents
    {
        internal event EventHandler<EventArgs> InternalEventToTest;
    }

    [TestClass()]
    public class EventTests
    {
        [TestMethod]
        public void ClassWithEvents_InternalEventTest()
        {
            //Arrange
            bool eventRaised = false;
            ClassWithEvents classWithEvents = Mock.Create<ClassWithEvents>();
            classWithEvents.InternalEventToTest += (object sender, EventArgs e) =>
            {
                eventRaised = true;
            };

            // Act
            Mock.Raise(() => classWithEvents.InternalEventToTest += null, new EventArgs());

            // Assert
            Assert.IsTrue(eventRaised);
        }
    }
}

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);
}

The required configuration for code coverage transparent integration has been changed since 2020.2 release and currently JustMock integration with dotCover is not working as expected. Manually applying the extra entries fixes the issue with execution, but there is no actual coverage collection.

When a breakpoint is added inside an async test that uses JustMock the debugger is failing to hit it. 

To reproduce the issue follow the next steps:

1. Open the attached project

2. Create a breakpoint at the first arrangement in the async test method.

3. Start debugging the async test

Result: the breakpoint is not hit.

The issue is observed for both .NET Core and .NET Framework.

Integration with Visual Studio Enterprise Code Coverage does not work if the project refers Microsoft.NET.Test.Sdk package version 16.3 (and above). The test run fails with exception:

Telerik.JustMock.Core.ElevatedMockingException : Cannot mock '<type to mock goes here>'. The profiler must be enabled to mock, arrange or execute the specified target.
    Detected active third-party profilers:
    * C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Team Tools\Dynamic Code Coverage Tools\amd64\covrun64.dll (from process environment)
    Disable the profilers or link them from the JustMock configuration utility. Restart the test runner and, if necessary, Visual Studio after linking.

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.

I have a class, which has a private async method, which has a local function, like the following example

 

internal class TestClass

{

 ......

        private async Task<bool> TestPrivateMethod()
        {
            var x = await TestLocalFunction();
            return x;

            async Task<bool> TestLocalFunction()
            {
                await Task.Delay(5);
                return true;
            }
 }

 

When I try to mock the local function, thows an error "System.MissingMemberException : C# 7 local function 'TestLocalFunction' with the given signature was not found inside method 'TestPrivateMethod'"

 

var testClassInstance = Mock.Create<TestClass>(Behavior.CallOriginal);

Mock.Local.Function.Arrange<Task<bool>>(testClassInstance, "TestPrivateMethod", "TestLocalFunction").Returns(Task.FromResult(true));

The test execution of a test hangs forever. Please see the attached VS 2019 Solution that contains one TestMethod.

R2 2020 is unusable. I reverted back to R1 and there the tests succeed in less than a second.

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?

The integration between JustMock and dotCover stopped working with R2 2019. The result when code coverage is started is that all tests remain in pending state and does not finish while the CPU is idle.

A class property get wrongly mocked when used as parameter for arranging other class methods. The following sample demonstrates the scenario:

class Foo
{
	public string Prop{ get; set; }

	public void Bar(string val)
	{
	}
}

[TestMethod]
public void Sample()
{
	var sut = Mock.Create<Foo>(Behavior.CallOriginal);

	Mock.Arrange(() => sut.Bar(sut.Prop)).DoNothing();

Mocking an async calls alse triggers hidden mocking of the return type. Depending of the type it might cause unexpected behavior or exception.
