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.

Referencing the nuget Microsoft.ApplicationInsights.AspNetCore V2.20.0 in the project that is tested leads to the VS 2019 code coverage failing to produce the report. Here are the steps to reproduce:

1. Create a project from the template ASP.NET Core Web API targeting .NET 5

2. Add a reference to the nuget package Microsoft.ApplicationInsights.AspNetCore V2.20.0

3. Create a unit test project from the C# JustMock Test Project (.NET Core) template.

4. Run the VS code coverage.

Expected result: the code coverage report is produced.

Actual result: there is no code coverage report

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.

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.

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();
    }
}

Some years ago, we committed ourselves to introduce support in Telerik JustMock for all new technology trends as soon as we can. We will introduce support for the official .NET 7 version following this commitment.

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.

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.

Using the mentioned (or later) product version, the following simple test fails (throws NullReferenceException):

[TestMethod]
public void TestMethod()
{
    var cultureInfo = Mock.Create<CultureInfo>();
    var thisThrowsAnException = cultureInfo.Name;
}

One of the possible workarounds is to create a mock like this:

readonly string cultureName = CultureInfo.InvariantCulture.Name;
...
var cultureInfo = Mock.Create(() => new CultureInfo(cultureName));

The case is reproducible (but might not be limited to) in a dedicated environment including Windows 10, JustMock R3.2021, Visual Studio 2019 and .NET 5. When the profiler is enabled the Visual Studio has problems with the test discovery and reports "Stack overflow" exception. The same applies to building solutions with Azure Function project.

Currently, JustMock extension always uses the profiler deployed by the installation, which may be different from the one deployed by the JustMock.Commercial package. This could lead to unexpected failures in the rest run and different results inside and outside Visual Studio.

Currently argument matchers like Arg.IsAny and Arg.Matches (and the corresponding ones used in NonPublic API Arg.Expr) accept types only as generic arguments, which makes the type specification at runtime impossible.

C# 8 introduces default interface method implementations. Attempt to mock such methods with JustMock in elevated mode fails. The following example illustrates the issue:

public interface IMyInterface
{
    int IntProperty { get => 0; }
}


[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        var mock = Mock.Create<IMyInterface>();
        Mock.Arrange(() => mock.IntProperty).Returns(1);

        Assert.AreEqual(1, mock.IntProperty);
    }
}
