我试图发现如何将async和await关键字应用于我的xUnit测试.我使用的是xUnit 1.9和Async CTP 1.3.这是我的测试用例

我有一个接口,它指定一个异步方法调用

public interface IDoStuffAsync
{
    Task AnAsyncMethod(string value);
}

我有一个使用接口并调用异步方法的类

public class UseAnAsyncThing
{
    private readonly IDoStuffAsync _doStuffAsync;

    public UseAnAsyncThing(IDoStuffAsync doStuffAsync)
    {
        _doStuffAsync = doStuffAsync;
    }

    public async Task DoThatAsyncOperation(string theValue)
    {
        await _doStuffAsync.AnAsyncMethod(theValue);
    }
}

在我的测试中,我希望检查方法DoThatAsyncOperation是否使用正确的值调用方法,因此我模拟了接口并使用Moq来验证调用

    [Fact]
    public async void The_test_will_pass_even_though_it_should_fail()
    {
        var mock = new Mock<IDoStuffAsync>();
        var sut = new UseAnAsyncThing(mock.Object);

        mock.Setup(x => x.AnAsyncMethod(It.IsAny<string>()));

        await sut.DoThatAsyncOperation("test");

        // This won't throw a Moq.MockExcpetion so the test appears to pass
        // However it does …
