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.

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.

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);
    }
}

Currently, when the JustMock profiler is enabled it provides a performance hit on the test execution. This effect is expected because a profiler is involved.

What we can do is find a more optimized way of instrumenting the methods.

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));
