MVC Razor View渲染测试

Question

我正试图找出一种方法来检查剃刀视图在测试中呈现的HTML.

我一直在看人们提出类似问题的帖子,但每一次,我都做不到.我得到的问题是视图引擎尝试加载.cshtml文件.它从函数中返回一个空引用异常.

[Test]
public void GetRazorViewEngine() {
    var _HttpContextBaseMock = new Mock<HttpContextBase>();
    var _HttpRequestMock = new Mock<HttpRequestBase>();
    var _HttpResponseMock = new Mock<HttpResponseBase>();
    _HttpContextBaseMock.SetupGet(x => x.Request).Returns(_HttpRequestMock.Object);
    _HttpContextBaseMock.SetupGet(x => x.Response).Returns(_HttpResponseMock.Object);

    var routeData = new RouteData();
    routeData.Values.Add("controller", "Home");
    routeData.Values.Add("action", "About");

    var controller = new HomeController();
    controller.ControllerContext = new 
    ControllerContext(_HttpContextBaseMock.Object,
                      routeData,
                      controller);
    controller.Url = new UrlHelper(new RequestContext(_HttpContextBaseMock.Object, routeData),
                                   new RouteCollection());


    var razorEngine = ViewEngines.Engines
                                 .Where(x => x.GetType() == typeof(System.Web.Mvc.RazorViewEngine))
                                 .FirstOrDefault();

    var path = "/Users/dan/Projects/Playground/MvcPlayground/Views/Home/About.cshtml";
    var master = "/Users/dan/Projects/Playground/MvcPlayground/Views/Shared/_Layout.cshtml";

    ViewEngineResult viewEngineResult = razorEngine.FindView(controller.ControllerContext,
                                                             path,
                                                             master,
                                                             false);
}

这是错误的堆栈跟踪.

查看（Razor引擎找不到视图）还请注意，RazorViewEngine过去在预编译视图方面存在一些问题： https: //github.com/aspnet/Mvc/issues/6672。然而，在我看来，RazorViewEngine 在过去 5 年内发生了一些变化。我想说是时候更新并重试了。
