我在使用 RenderPartialViewToString 进行单元测试时遇到了很多麻烦。我成功地做了两件事。我不得不模拟视图引擎和控制器上下文。
这里的代码:
public ViewEngineResult SetupViewContent(string viewName, string viewHtmlContent)
{
var mockedViewEngine = new Mock<IViewEngine>();
var resultView = new Mock<IView>();
resultView.Setup(x => x.Render(It.IsAny<ViewContext>(), It.IsAny<TextWriter>()))
.Callback<ViewContext, TextWriter>((v, t) =>
{
t.Write(viewHtmlContent);
});
var viewEngineResult = new ViewEngineResult(resultView.Object, mockedViewEngine.Object);
mockedViewEngine.Setup(x => x.FindPartialView(It.IsAny<ControllerContext>(), viewName, It.IsAny<bool>()))
.Returns<ControllerContext, string, bool>((controller, view, useCache) =>
{
return viewEngineResult;
});
mockedViewEngine.Setup(x => x.FindView(It.IsAny<ControllerContext>(), viewName, It.IsAny<string>(), It.IsAny<bool>()))
.Returns<ControllerContext, string, string, bool>((controller, view, masterName, useCache) =>
{
return viewEngineResult;
});
ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(mockedViewEngine.Object);
return viewEngineResult;
}
public void SetContext(ref PointCollecteLivraisonController controller)
{
SetupViewContent("MyViewName", "TheViewContent");
var httpContextBase = new Mock<HttpContextBase>();
var httpRequestBase = new Mock<HttpRequestBase>();
var response = new Mock<HttpResponseBase>();
var session = new Mock<HttpSessionStateBase>();
var routes = new RouteCollection();
RouteConfigurator.RegisterRoutes(routes);
var routeData = new RouteData();
routeData.Values.Add("controller", "PointCollecteLivraison");
routeData.Values.Add("action", "RechercheJson");
httpContextBase.Setup(x => x.Response).Returns(response.Object);
httpContextBase.Setup(x => x.Request).Returns(httpRequestBase.Object);
httpContextBase.Setup(x => x.Session).Returns(session.Object);
session.Setup(x => x["somesessionkey"]).Returns("value");
httpRequestBase.Setup(x => x.Form).Returns(new NameValueCollection());
controller.ControllerContext = new ControllerContext(httpContextBase.Object, routeData, controller);
controller.Url = new UrlHelper(new RequestContext(controller.HttpContext, routeData), routes);
}
这就是我使用它的方式:
PointCollecteLivraisonController controller = new PointCollecteLivraisonController();
SetContext(ref controller);
这是我的来源:查看引擎模拟:http: //thoai-nguyen.blogspot.fr/2011/04/test-mock-mvc-view-engine.html
控制器上下文模拟:ASP.NET MVC - 使用 Moq 框架对 RenderPartialViewToString() 进行单元测试?
希望这有帮助。
