我正在创建一个非常简单的ViewResult子类JavaScriptViewResult，它在执行时调用基本实现，然后将Content-Type响应设置为text/javascript. 在尝试对此类进行单元测试时，我遇到了许多困难，以实现 ASP.NET MVC 堆栈的所有依赖项。

这是我使用 Rhino 的单元测试到目前为止的样子：

[TestMethod]
public void TestExecuteAction()
{
    var request = MockRepository.GenerateMock<HttpRequestBase>();
    request.Expect(m => m.Url).Return(new Uri("/Test/JavaScript", UriKind.Relative));

    var httpContext = MockRepository.GenerateMock<HttpContextBase>();
    httpContext.Expect(m => m.Request).Return(request);

    var controller = MockRepository.GenerateMock<ControllerBase>();

    var virtualPathProvider = MockRepository.GenerateMock<VirtualPathProvider>();

    var routeCollection = new RouteCollection(virtualPathProvider);
    routeCollection.MapRoute("FakeRoute", "Test/JavaScript", new { controller = "Test", action = "JavaScript" });
    var routeData = routeCollection.GetRouteData(httpContext);

    var context = new ControllerContext(httpContext, routeData, controller);

    var viewResult = new JavaScriptViewResult();
    viewResult.ExecuteResult(context);

    Assert.AreEqual("text/javascript", context.HttpContext.Response.ContentType);
}

运行测试时的最新例外NullReferenceException是System.Web.Routing.Route.GetRouteData(HttpContextBase httpContext).

如何设置所有依赖项以执行ViewResult? 有什么技术可以让这更简单吗？或者，有没有不同的方法可以利用 MVC 视图引擎生成 JavaScript 来设置正确Content-Type的响应？

我想出了如何满足ViewResult. 我遇到的一个问题是嘲笑寻找视图的过程。这可以通过确保View填充我的对象的属性来避免。这是我的工作测试：

[TestMethod]
public void TestExecuteAction()
{
    var response = MockRepository.GenerateStub<HttpResponseBase>();
    response.Output = new StringWriter();

    var httpContext = MockRepository.GenerateMock<HttpContextBase>();
    httpContext.Expect(m => m.Response).Return(response);

    var routeData = new RouteData();
    routeData.Values.Add("action", "FakeAction");

    var context = new ControllerContext(httpContext, routeData, MockRepository.GenerateMock<ControllerBase>());

    var viewResult = new JavaScriptViewResult();
    viewResult.View = MockRepository.GenerateMock<IView>();
    viewResult.ExecuteResult(context);

    Assert.AreEqual("text/javascript", context.HttpContext.Response.ContentType);
}
