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!

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.

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();
}

using NUnit.Framework;
using Telerik.JustMock;

namespace Example
{
    public class MyClass
    {
        public MyClass(int a = 5) { }
    }

    [TestFixture]

        }
    }

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.

I need to be able to mock in Winrt. If that is already possible, then you need to spell out in example form how that is done.

Hi there, I'm a developer on OzCode, a Visual Studio extension ( www.oz-code.com ).

We've received some complaints from customers that OzCode is incompatible with JustCode. I installed JustMock, and saw that when Visual Studio starts up, JustMock it seems to be causing a crash in a child process that OzCode spawns off of devenv.exe, which is called 'BugAidMetadataLoader.exe':

The exception in this process is:

Additional information: Could not load type 'Telerik.JustMock.Profiler' from assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

I would guess that JustMock is unintentionally causing the process to be loaded with a CLR Profiler attached and injecting code into it, and the injected code causes the crash.

Could you please provide some advice on how to avoid this, or possibly provide a fix?

Thank you very much,
 - Omer Raviv, OzCode

If I have a constructor like this: public Foo(IAccount fromAccount, IAccount toAccount) { //code }, I need to be able to distinguish between the two accounts when automocking.
container.Arrange<IAccount>() won't work.  Perhaps container.Arrange<IAccount>[0] would.

I have installed the trial version of JustMock to evaluate it. I have been trying to mock the static calls of Azure RoleEnvironment class, but the SetupStatic does not work. It seems to be calling the original method. Please see my simple test below:

[Test]
public void VerifyRoleEnvironment()
{
       bool expected = true;
       Mock.SetupStatic(typeof(RoleEnvironment), StaticConstructor.Mocked);
       Mock.Arrange(() => RoleEnvironment.IsAvailable).Returns(true);
       Assert.AreEqual(expected, RoleEnvironment.IsAvailable);
}

1. Load the attached project in Visual Studio 2013.
2. Update the NuGet packages (NUnit).
3. Update the reference to JustMock to point to the correct path to a retail version of Telerik.JustMock.dll.
4. Run tests in NUnit runner (or any other runner that will run them in the same process/sequentially.
5. --> Notice that the first TestCase will pass, the second will fail.
6. Run the two test cases separately.
7. --> Notice that they both pass.
8. Remove the reference to Telerik.JustMock.dll.
9. Use NuGet to get the latest JustMock Lite.
10. Run the tests again.
11. --> Notice that they both pass.

This appears to be a bug with JustMock (retail) 2013.3.1119.2.  The bug does not reproduce when using JustMock Lite from NuGet.

If you drop into a debugger and step through both tests in a row you see the following behavior:
1. When the first test is started (after SetUp has been called) FlagA is correctly set to true and FlagB is defaulted to false.
2. When you step over the Mock.Arrange, FlagA is still true and FlagB is set to the value of input (order of running tests doesn't appear to matter, second always fails).
3. When the second test starts (after SetUp has been called again) Flag A is correctly set to true and FlagB is defaulted to false.
4. When you step over the Mock.Arrange, FlagB is set to the value of input but FlagA has been reverted to default!

If you add several other properties to the interface they will all be reset to default (no matter how many you arrange) when the second test executes the Mock.Arrange.

This bug reproduces without the JustMock profiler attached, and also with the profiler attached.

The version of JustMock Lite that was tested against is 2014.1.1217.4.  When I run the Telerik Control Panel I am not prompted to update my version of JustMock beyond 2013.3.1119.2 (perhaps this bug is already fixed and I just need to figure out how to upgrade).

Values from already mocked methods are not taken into account when initializing a static constructor from the Telerik.JustMock.PrivateAccessor class.

Here is an example: PrivateAccessor.ForType(typeof(Foo)).SetField("someStringField", "stringvalue");

A workaround is to call the: Mock.Intercept(typeof(Foo)); before calling the PrivateAccessor.
