Moq.模拟委托输入

我试图模拟一个委托，使用Moq，但到目前为止，我所做的一切都是徒劳的。我做了一个小例子来说明如何设置:

1。代理类正在抽象WCF服务

public interface IServiceProxy
{
    void FooService(ServiceProxy.FooServiceDelegate service);
}
public class ServiceProxy : IServiceProxy
{
    private readonly EndpointAddress _fooServiceEndpoint;
    public ServiceProxy(IConfiguration configuration)
    {
        _fooServiceEndpoint = new EndpointAddress(new Uri(configuration.WcfServiceEndpoint));
    }
    public delegate void FooServiceDelegate(IFooBar proxy);

    public void FooService(FooServiceDelegate service)
    {
        Do<IFooBar>((service.Invoke), _fooServiceEndpoint);
    }

    private void Do<T>(UseServiceDelegate<T> f, EndpointAddress address)
    {
        UsingService<T>.Use(f.Invoke, address);
    }
}

2。服务定义

/// <summary>
/// This is the interface the WCF service exposes
/// </summary>
public interface IFooBar
{
    string Hello(string name);
}

3。以及使用代理

的类

public class DoFoo
{
    private readonly IServiceProxy _serviceProxy;
    public DoFoo(IServiceProxy serviceProxy)
    {
        _serviceProxy = serviceProxy;
    }

    public string SayHello(string name)
    {
        var response = string.Empty;
        _serviceProxy.FooService(proxy => { response = proxy.Hello(name); });
        return response;
    }
}

我想测试在委托FooServiceDelegate上定义的方法与输入IFooBar实际上被调用，并且我希望能够通过委托模拟IFooBar上的方法调用的响应。

到目前为止，我的尝试都是徒劳的，所以我希望这里有一些moq专家可以帮助我。

这是一个测试的例子，当然不能像现在这样工作。

[TestClass()]
public class DoFooTests
{
    [TestMethod, TestCategory("Unit")]
    public void SayHelloJohn_ShouldUseServiceProxy()
    {//SETUP
        var serviceMock = new Mock<IFooBar>(MockBehavior.Loose);
        var delegateMock = new Mock<ServiceProxy.FooServiceDelegate>(MockBehavior.Strict);
        var serviceProxyMock = new Mock<IServiceProxy>(MockBehavior.Strict);
        serviceProxyMock.Setup(m => m.FooService(delegateMock.Object));
        var name = "John";
        var response = $"Hello {name}";
        //Im trying something like this (of course this does not work...)
        delegateMock.Setup(m => m.Hello(name)).Returns(response);
        //EXECUTE
        var doFoo = new DoFoo(serviceProxyMock.Object);
        var result = doFoo.SayHello(name);
        //ASSERT
        // Do some assertions here....
    }
}

[TestMethod]
public void SayHelloJohn_ShouldUseServiceProxy()
{
    const string EXPECTED_RESULT = "Hello John";
    const string NAME = "John";
    var fakeServiceProxy = new Mock<IServiceProxy>(MockBehavior.Strict);
    var fakeFooBar = new Mock<IFooBar>(MockBehavior.Loose);
    fakeFooBar.Setup(bar => bar.Hello(NAME)).Returns(EXPECTED_RESULT);
    fakeServiceProxy.Setup(proxy => proxy.FooService(
                    It.IsAny<ServiceProxy.FooServiceDelegate>()))
                    .Callback<ServiceProxy.FooServiceDelegate>(arg => arg(fakeFooBar.Object));
    var target = new DoFoo(fakeServiceProxy.Object);

    var result = target.SayHello(NAME);
    Assert.AreEqual(EXPECTED_RESULT, result);
}
