HttpFileCollectionBase:模拟计数属性

Question

我尝试模拟HttpFileCollectionBase实例的Count-Property - 但不知何故它不起作用.

var fakedRequest = new Mock<HttpRequestBase>();
var fakedFile = new Mock<HttpPostedFileBase>();
fakedFile.SetupGet(x => x.InputStream).Returns(inputStream);
var fakedFileCollection = new Mock<HttpFileCollectionBase>();
fakedFileCollection.SetupGet(x => x.Count).Returns(1);
fakedRequest.SetupGet(x => x.Files).Returns(fakedFileCollection.Object);
fakedRequest.SetupGet(x => x.Files[0]).Returns(fakedFile.Object);

var sut = new TestableExploreController(null, fakedTemporaryStorageRepository.Object)
    {
         HttpRequest = fakedRequest.Object
    };

如你所见,我创建了一个模拟的HttpRequest,我将其注入到被测系统中.Count-Property被定义为返回1 - 但它总是返回0.我正在使用Moq.

我究竟做错了什么？

Scott Hanselman 在此博文中写道.问题是以下几行:

fakedRequest.SetupGet(x => x.Files[0]).Returns(fakedFile.Object);

尝试这样,它应该工作:

var fakedRequest = new Mock<HttpRequestBase>();
var fakedFile = new Mock<HttpPostedFileBase>();
fakedFile.SetupGet(x => x.InputStream).Returns(inputStream);
var fakedFileCollection = new Mock<HttpFileCollectionBase>();
fakedFileCollection.SetupGet(x => x.Count).Returns(1);
fakedFileCollection.SetupGet(x => x[0]).Returns(fakedFile.Object);
fakedRequest.SetupGet(x => x.Files).Returns(fakedFileCollection.Object);
