1. 1.MoqMock Repository时最好是Mock Repository的接口,这样会避免不知名的错误。

    var mockClubRepository = new Mock<IClubRepository>();
    
    mockClubRepository.Setup(mr => mr.GetById(It.IsAny<Guid>()))

    2.Moq 中怎样返回空(How to return null in Moq):

    mockRepository.Setup(mr => mr.GetItems()).Returns(() => null);

    这种写法很常用,比如返回一个空的List

    mockRepository.Setup(mr => mr.GetItems()).Returns(() => new List<Object>);

     3.怎样Mock一个IsValid == false ModelState

    很简单:UsersController.ModelState.AddModelError("username","Bad username"); 添加个ModelError就可以改变ModelStateIsValid属性了。

    4.How to Mock User.Identity.Name

     

    Testing controller Action that uses User.Identity.Name

     

    ControllerCreateControllerForUser(string userName) 
    {
        var mock = newMock<ControllerContext>();
        mock.SetupGet(p => p.HttpContext.User.Identity.Name).Returns(userName);
        mock.SetupGet(p => p.HttpContext.Request.IsAuthenticated).Returns(true);
    
        var controller = newSomeController();
        controller.ControllerContext = mock.Object;
    
        return controller;
    }

    5. 有时候需要单元测试文件上传,那么怎么去Mock一个上传的文件呢?

    原理很简单,只需要MockHttpContext.Request.Files的一些需要的属性即可,例如:

    View Code

    ASP.NET MVC中,上传的文件都是放在HttpPostedFileBase这个对象中,我们可以直接Mock这个对象,对保存文件的方法进行单元测试

    View Code
     [TestMethod]
    
            public void TestUpLoadFile()
    
            {
    
                var mockFile = new Mock<HttpPostedFileBase>();
    
                mockFile.Setup(d => d.FileName).Returns("test.txt");
    
                mockFile.Setup(d => d.ContentLength).Returns(100);
    
                mockFile.Setup(d => d.InputStream).Returns(new MemoryStream());
    
     
    
                const string uploadsFolder = "D:\\UploadedFiles";
    
                Domain.DMS.File file = _fileService.UploadedFile(mockFile.Object, uploadsFolder);
    
     
    
                Assert.AreEqual("test.txt", file.FileName);
    
                Assert.AreEqual(100, file.FileSize);
    
                Assert.AreEqual("txt", file.FileExtension);
    
            }
