Mocking of these methods could not be made due to compiler (CS8175) or runtime (System.InvalidProgramException: Cannot create boxed ByRef-like values) errors.

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.

if you use the C# using declaration and have JustMock advanced (elevated) mode enabled, the runtime will throw an InvalidProgramException.

Find below the sample code that demonstrates the issue:

public class TestClass : IDisposable
{
    public void Dispose()
    {
    }
}

[TestClass]
public class Fixture
{
    public interface ITest { }

    [TestMethod]
    public async Task Test()
    {
        ITest mock = Mock.Create<ITest>();
        using TestClass test = new();
    }
}

Integration with dotCover is only available through Telerik.JustMock.Configuration.exe, which works with the machine's registry and needs JustMock to be installed. This approach is not applicable to cloud-based build agents and therefore we need an integration that does not require the installation of JustMock.

A unit test run against a simple class using EntityFramework never completes, here's the code:

public class DbContext1 : DbContext
{
    public DbContext1(string connectionString)
    {
    }
}

public class Program
{
    private static readonly SemaphoreSlim _lock = new SemaphoreSlim(1, 1);

    public async Task Run()
    {
        await _lock.WaitAsync();
        try
        {
            await InsertDbRow();
        }
        finally
        {
            _lock.Release();
        }
    }

    private static async Task InsertDbRow()
    {
        await RetryWrapperAsync(async () =>
        {
            using DbContext1 dbContext = new DbContext1("con str");
            await dbContext.SaveChangesAsync();
        });
    }

    public static async Task RetryWrapperAsync(Func<Task> operation)
    {
        for (int i = 0; i < 3; i++)
        {
            try
            {
                await operation();
                break;
            }
            catch (Exception)
            {
                await Task.Delay(100);
            }
        };
    }
}

[TestClass]
public class ProgramTest
{
    private readonly DbContext1 mockContext1 = Mock.Create<DbContext1>();

    [TestInitialize]
    public void SetUp()
    {
        Mock.Arrange(() => new DbContext1("con str")).Returns(mockContext1);
    }

    [TestMethod]
    public async Task TestMethod()
    {
        // Arrange
        Program program = new Program();

        // Act
        await program.Run(); // <-- at this point the test hangs
    }
}

Adding do-nothing arrangement on mockContext.SaveChanges fixes the hang, but the expectation is that mock will handle this case by default and there is no need to be explicitly arranged.

The threading model of UI apps differs from the test host and this might become a source of issues like the following: System.InvalidOperationException: "The calling thread must be STA, because many UI components require this". The request is about extending JustMock with some helpers that can be used to solve this issue easily.

Coverlet (https://github.com/coverlet-coverage/coverlet) is a cross-platform .NET code coverage tool, so the integration should be considered for all currently (and also potentially) supported platforms by JustMock.

Code Coverage Wrapper data collector strictly follows the installation directory structure and it makes installation-free usage really hard (with JustMock.Commercial NuGet package for example). Adding some configuration settings will solve this issue.

Considering the sample class

using Azure.Messaging.ServiceBus;

public class Class2
{
	private static ServiceBusSender messageToTopicSender;
	private static string topicName;

	public static void SetRequestTopicClient(string serviceBusConnectionString, string topName)
	{
		topicName = topName;

		ServiceBusClient serviceBusClient = new ServiceBusClient(serviceBusConnectionString);
		messageToTopicSender = serviceBusClient.CreateSender(topicName);
	}
}

and the following tests

[TestClass]
public class Class1Test
{
	[TestInitialize]
	public void SetUp()
	{
		Mock.Arrange(() => Class2.SetRequestTopicClient("", "")).DoNothing();
	}

	[TestMethod]
	public void TestA()
	{
		Class2.SetRequestTopicClient("", "");
	}
}

[TestClass]
public class Class2Test
{
	static ServiceBusClient serviceBusClient = Mock.Create<ServiceBusClient>();
	ServiceBusSender messageToTopicSender = Mock.Create<ServiceBusSender>();

	[TestInitialize]
	public void SetUp()
	{
		Mock.Arrange(() => new ServiceBusClient("conStr")).Returns(serviceBusClient);
		Mock.Arrange(() => serviceBusClient.CreateSender("myTopic")).Returns(messageToTopicSender);
	}

	[TestMethod]
	public void TestB()
	{
		Class2.SetRequestTopicClient("conStr", "myTopic");
	}
}

Executing the tests in order TestA -> TestB results in failed TestB, but changing the order or runining them standalone succeeds.The outcome of the tests should not be dependent of the execution order.

Adding JustMock to the Extensions section under Assemblies in the Add Reference dialog will make it easier for the developers to find where the required dll is located.

I am in the process of building an internal developer platform on kubernetes. Historically, in order to run justmock on build servers we pointed to a special location of the windows registry for accessing the DLL. In kubernetes, the build runners are kubernetes nodes. Is there a preferred way to run these tests in this environment? I can provide more details if it is helpful or valuable. Historically, we used Azure Devops build agents in this new world dotnet test is being run in Linux gitlab agents and not windows. I would have chosen linux in the dropdown but wasn't available.

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(),
            });

The new public API should allow the developer to access the invocations for a particular arrangement. Something like the following:

IEnumerable<IInvocaiton> invocations = foo.GetInvocationsFor((x) => x.CalcData(2, 2));

Implement a new public API that will allow the developer to iterate over all invocations of mock arrangements. Something like the following:

IEnumerable<IInvocaiton> invocations = Mock.Invocations;

The documentation on Fluent Mocking ends with this statement:

Important

Note that when you use Fluent Asserts only arrangements marked with either MustBeCalled or Occurs will be verified. For other tests you have to use the explicit assert.

What this fails to note is that, while this is true of the function "Assert", there is another function, "AssertAll", which will flag an error if any Arranged function call was not utilized.

 

On a related note, I left other suggestions for this same page a day or two ago.  I would have liked to leave the above statement using the same feedback utility, but I can no longer find the control that I used to leave those initial suggestions.

String parameter "message" inside Mock.Assert APIs could be easily interpreted in the wrong way by associating them with the concrete assertion instead of the scope where this particular statement is taking place.
