Allow the developer to create custom behaviors and use them in an arrangement. Something like the following:

            Mock.Arrange(() => foo.CalcData(Arg.AnyInt, Arg.AnyInt), new IBehavior[]
            {
                new LogInvocation(),
                new ReturnBaseOrDefaultValue(),
            });

Hi.

i saw this: https://www.telerik.com/forums/how-can-i-mock-multiple-instances-of-a-struct

but still dont understand why JustMock works that way in the first place. why does it union struct mocks by value?

the above solution is only possible when i mock a struct i can change (and then add the id to it) but what about struct's from the framework that i cannot control? Is there a way to tell JustMock not to union mock structs?

Thanks,

Yosi

Dear Telerik team,
It is nice to have a way to generate mocks.

But it is annoying to have lots of those messages for references in XML comments. I had to turn the feature off. Which might be the case for other customers too.

Maybe you want to have a look into it.

We're developing .net 5/core services, using Rider IDE and MacOS.

Please:

1. Add support to run JustMock under MacOS (profiler need to be supported, enabled issue, etc.), or if already supported, please provide instructions of how to activate it per test, for example using NUnit.

2. Add integration with Rider so all the process will be much easier.

I am unable to mock interfaces that contain a method with an `in` parameter. When running the following code snippet, the result is an exception:

Message: 
  Test method Example.UnitTests.UnitTest.TestMethod threw exception:
  Telerik.JustMock.Core.MockException: Abstract type 'Example.UnitTests.InParamExample' is not accessible for inheritance.

Stack Trace:

namespace Example.UnitTests
{
    using Microsoft.VisualStudio.TestTools.UnitTesting;
    using Telerik.JustMock;

    public interface ParamExample
    {
        void Foo(int param);
    }

    public interface InParamExample
    {
        void Foo(in int param);
    }

    [TestClass]
    public class UnitTest
    {
        [TestMethod]
        public void TestMethod()
        {
            var mockedParamExample = Mock.Create<ParamExample>();
            var mockedInParamExample = Mock.Create<InParamExample>();
        }
    }
}

Mock.Create<IPool>() fails with 

Telerik.JustMock.Core.MockException : Abstract type 'IPool' is not accessible for inheritance.
   In Telerik.JustMock.Core.MocksRepository.Create(Type type, MockCreationSettings settings)
   In Telerik.JustMock.Mock.<>c__39`1.<Create>b__39_0()
   In Telerik.JustMock.Core.ProfilerInterceptor.GuardInternal[T](Func`1 guardedAction) 

when trying to create a mock object from

public interface IPool
{
    object GetItem(in Struct a, out Class b);
}

JustMock interprets anonymous types as tuples. The sample below demonstrates the issue:

public interface IAnsweringService
{
    (int code, string desc) GetAnswer(string question);
}


[TestMethod]
public void AnswerToTheUniverseQuestionTest()
{
    var apiMock = Mock.Create<IAnsweringService>();

    var expectedAnswer = new { code = 42, desc = "Answer to the Ultimate Question of Life" };

    Mock.Arrange(() => apiMock.GetAnswer(Arg.AnyString)).Returns(expectedAnswer);

    var actualAnswer = apiMock.GetAnswer("What is a universe question answer?");

    Assert.AreEqual(expectedAnswer.code, actualAnswer.code);
    Assert.AreEqual(expectedAnswer.desc, actualAnswer.desc);
}

Telerik.JustMock.Core.MockException: The chained return value type '<>f__AnonymousType1`2[System.Int32,System.String]' is not compatible with the arranged method's return type 'System.ValueTuple`2[System.Int32,System.String]'

The following code snippet causes a hang in the test execution while being debugged:

Mock.SetupStatic(typeof(TimeSpan), Behavior.CallOriginal, StaticConstructor.NonMocked);
Mock.Arrange(() => TimeSpan.FromSeconds(15)).Returns(TimeSpan.MinValue);

The issue can be temporary solved by disabling the DebugWindow via JustMock extension menu. 

Hello

I generate a syntax tree which I will format with Formatter.Format() from the package Microsoft.CodeAnalysis.CSharp.Workspaces 4.4.0 and .NET 6. A test exists where the formatter is used but when the JustMock profiler is enabled an InvalidProgramException is thrown. When the profiler is disabled everything works fine. It fails on Windows and on Linux.

Exception

  Message: 
System.InvalidProgramException : Common Language Runtime detected an invalid program.

Reproduction

You can reproduce this by writing an unit test for that (I used xUnit):

        [Fact]
        public void Test1()
        {
            var classText = @"using System; namespace TestNameSpace.Orders { public class Order
                            {
                                public Guid Id { get; set; }
                            }
                        }";

            var syntaxTree = CSharpSyntaxTree.ParseText(classText);
            var workspace = new AdhocWorkspace();

            var formattedClassText = Formatter.Format(syntaxTree.GetRoot(), workspace).ToFullString();

            var expected = @"using System;
namespace TestNameSpace.Orders
{
    public class Order
    {
        public Guid Id { get; set; }
    }
}";
            Assert.Equal(expected, formattedClassText);
        }
    }

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:

Testhost process exited with error: Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
   at Microsoft.VisualStudio.TestPlatform.TestHost.Program.Main(System.String[])
. Please check the diagnostic logs for more information.

Test Run Aborted.

Considering the following simple test scenario:

public abstract class TestBase
{
    public static TestContext TestContext { get; set; }
}

[TestClass]
public class UnitTest1 : TestBase
{
    [ClassInitialize]
    public static void ClassInitlialize(TestContext ctx)
    {
        TestContext = ctx;
    }

    [TestMethod]
    public void TestMethod1()
    {

    }
}

[TestClass]
public class UnitTest2 : TestBase
{
    [ClassInitialize]
    public static void ClassInitlialize(TestContext ctx)
    {
        TestContext = ctx;
    }

    [TestMethod]
    public void TestMethod1()
    {

    }
}

Attempt to run the tests above with JustMock profiler enabled fails with System.InvalidProgramException. The issue is not reproducible with MSTest.TestFramework and MSTest.TestAdapter packages prior to 3.0.x.

The issue is demonstrated with the following sample:

[Theory]
[MemberData(nameof(GetMemberDataContext))]
public void ValidParameters_Success(int param1, int param2)
{
	// Arrange
	Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked);
        Mock.Arrange(() => MyClass.method1()).Returns(true);

        // Act
	IService service = new Service();
	bool result = service.method2();

	// Assert
	Assert.True(result);
	Mock.Assert(() => MyClass.method1(), Occurs.Once()); // <-- the test fails here because it reports that method invocation occurs twice
}

The issue in not observed if the code is modified in the following way, which indicates behavioral incinsistency:

[Theory]
[MemberData(nameof(GetMemberDataContext))]
public void ValidParameters_Success(int param1, int param2)
{
	// Arrange
	Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked);
        Mock.Arrange(() => MyClass.method1()).Returns(true).OccursOnce();

        // Act
	IService service = new Service();
	bool result = service.method2();

	// Assert
	Assert.True(result);
	Mock.Assert<MyClass>();
}

There are older releases with a version of 1.0.0.4 for the Telerik.JustMock.Console.exe and with the R3 2022 release, the version is 1.0.0.3.
