设置模拟注入对象

Question

我已经配置了 MockingKernel 以模拟依赖项：

[TestFixture]
public class TestsFixture
{
    private NSubstituteMockingKernel IoCKernel;

    public UsersTests()
    {
        this.IoCKernel = new NSubstituteMockingKernel();
    }

    [SetUp]
    public void SetUp()
    {
        this.IoCKernel.Reset();
    }

    [Test]
    public void AddUserTest()
    {
        var mock = this.IoCKernel.Bind<Core.Configuration.ICoreConfiguration>().ToMock();
        mock.Setup( <<<<<<< How to substitute methods of this mocked objects??????
            m =>
            m.UserIdentities
                .Returns(new List<UserIdentity>() {new UserIdentity("user1")}
        );

        Core.Kernel coreKernel = this.IoCKernel.Get<Core.Kernel>();
    }
}

根据 this documentation，我需要调用 Setup 方法来替换方法。尽管如此，Setup 方法不可用。

有什么想法吗？

我已阅读文档。我要一些例子。不过，我认为文档有点差。

编辑

我试过这个：

public void Test() {

    Core.Configuration.UserIdentity userConfiguration = Core.Configuration.UserIdentity.Create("u1", "p1");
    IEnumerable<Core.Configuration.UserIdentity> configurationUsers = new List<Core.Configuration.UserIdentity>() { userConfiguration };

    this.IoCKernel.Get<Core.Configuration.ICoreConfiguration>().UserIdentities.Returns(configurationUsers);

    //Testing
    Core.Kernel kernel = this.IoCKernel.Get<Core.Kernel>();
    kernel.Received(1).AddUser(Arg.Any<Core.Identity.UserIdentity>());
}

尽管如此，我现在在最后一行收到此 NSubstitute.Exceptions.NotASubstituteException 异常消息：

NSubstitute extension methods like .Received() can only be called on objects created using Substitute.For() and related methods.

如您所见，我正在尝试测试 AddUser 方法至少被调用一次。 AddUser 必须根据我的 Core.Kernel 实现调用。

这是一个工作示例：

using Ninject;
using Ninject.MockingKernel.NSubstitute;
using NSubstitute;
using NUnit.Framework;

namespace ClassLibrary1
{
    [TestFixture]
    public class MyTests
    {
        [Test]
        public void Test1()
        {
            using (var kernel = new NSubstituteMockingKernel())
            {
                var substitute = kernel.Get<IDummyService>();
                substitute.ReturnInt().Returns(1);

                var instance = kernel.Get<DummyClass>();
                Assert.AreEqual(1, instance.Calc());
                substitute.Received(1).ReturnInt();
            }
        }

        public interface IDummyService
        {
            int ReturnInt();
        }

        public class DummyClass
        {
            private IDummyService _dummyService;

            public DummyClass(IDummyService dummyService)
            {
                _dummyService = dummyService;
            }

            public int Calc()
            {
                return _dummyService.ReturnInt();
            }
        }
    }
}

使用以下包：
