I filed a prior ThreadLeak:

Thread leak in JustMock (telerik.com)

 

I think I've found another one: (VS version 16.10.31321.278)

telerik_justmock_debugwindow_service_client!Telerik.JustMock.DebugWindow.Service.Client.ServiceHostMonitor.MonitorTimer_Elapsed

Apparently, the MonitorTimer_Elapsed code is running on a threadpool thread and it takes longer than 1 sec (perhaps it's waiting on a lock?).

Another timer tick occurs and the method is called again. Eventually, the ThreadPool runs out of threads and grows by about 1 thread per second (1Mb /sec leak)

In one dump 2Gig was used (1962 threads on the same MonitorTimer_Elapsed stack frame)

In that same dump there were 52 stacks with this frame:

telerik_justmock_debugwindow_service_client!Telerik.JustMock.DebugWindow.Service.Client.ConnectionSetupServiceClientBase`[[System.__Canon,mscorlib]].get_ServiceAvailable

(this was the same item as my prior report).

The following test fails:

[TestMethod]
public void TestCallOrderWithInOrder()
{
	// Arrange
	var mockClass1 = Mock.Create<Class1>();
	var mockClass2 = Mock.Create<Class2>();

	Mock.Arrange(() => mockClass1.Method1())
		.InOrder();
	Mock.Arrange(() => mockClass2.Method1())
		.InOrder()
		.Occurs(2);
	Mock.Arrange(() => mockClass1.Method2())
		.InOrder();

	// Act
	mockClass1.Method1();

	mockClass2.Method1();
	mockClass2.Method1(); // <--- this call is not allowed by
						  //      InOrder clause currently 
						  //      and throws AssertFailedException

	mockClass1.Method2();

	// Assert
	Mock.Assert(mockClass1);
	Mock.Assert(mockClass2);
}

The following test is not working anymore since version JustMock_2021_2_615_4 but was working with JustMock_2021_1_326_1 and older versions:

public interface ITest
{
    void Test(string text);
}

[TestMethod]
public void MyTestMethod()
{
    var mock = Mock.Create<ITest>();
    Mock.Arrange(() => mock.Test("")).IgnoreArguments().OccursNever();
    Mock.Arrange(() => mock.Test(Arg.Matches<string>(a => a == "a"))).InOrder().OccursOnce();
    Mock.Arrange(() => mock.Test(Arg.Matches<string>(a => a == "b"))).InOrder().OccursOnce();


    mock.Test("a");
    mock.Test("b");

    Mock.Assert(mock);
}

If I remove the OccorsNever line, its working.
If I remove the 2 InOrder, its working.

Seems that something change there: https://www.telerik.com/support/whats-new/justmock/release-history/justmock-r2-sp1-2021

Using elevated mocking mode (profiler enabled) with long path names for the test containers (above 260 characters) causes the following command:

dotnet test

to fail with error:

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));

Thread leak in JustMock

I am a member of the Visual Studio Perf Reliability team

 

Recently, I’ve found several customer dumps with huge # of threads.

In this dump:

Watson : Cab Search (microsoft.com)

 

Thd_ThreadStack_telerik_justmock_debugwindow_service_client!Telerik.JustMock.DebugWindow.Service.Client.ConnectionSetupServiceClientBase`[[System.__Canon,mscorlib]].get_ServiceAvailable

2,136,997,888

 

Progress® Telerik® JustMock Feedback Portal

 

There are 2084 threads using 2G mem, most with the stack below:

This is caused by threadpool starvation: the JustMock call ties up a thread for more than 1 second, then another request comes in.

The CLR will create an additional thread after 1 second to satisfy the request. This keeps happening and creates thousands of threads, each with size 1Meg.

when using JustMock Free in a net 5.0 app.  I am getting an Ninject exception that IAssemblyNameRetriever could not be found.  Looking at the code on github,

the NETCORE compile constant removes the line

AddComponent<IAssemblyNameRetriever, AssemblyNameRetriever>();

from StandardKernel.cs

however, CompiledModuleLoaderPlugin uses IAssemblyNameRetriever in it's constructor and

AddComponent<IModuleLoaderPlugin, CompiledModuleLoaderPlugin>();

is still included in the NETCORE version.

JustMock should support .NET 5

Hi Team,

The main telerik.com site is blocked in Sweden. I spoke to my VPN provider and got the exit IP address (217.64.148.92).

They said that the IP address used to be listed as an Iran IP in older GEO IP databases, which would explain why https://telerik.com is not working, even though it is from Stockholm

Can you please double check that your GEO IP database is not listing the Swedish IP address as being in Iran?

Thank you,

Markus

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);
        }
    }
}

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.
