C#模拟Request.Browser.MajorVersion使用RhinoMocks

c/c++ 来源:johnstaveley 3次浏览

我有在MVC控制器以下代码:C#模拟Request.Browser.MajorVersion使用RhinoMocks

 var isIe6 = Request.Browser.Type.ToUpper().Contains("IE") && Request.Browser.MajorVersion < 7; 

我需要存根出使用犀牛制品的第二部分。我曾经尝试这样做:

HttpRequest.Stub(a => a.Browser).Return(new HttpBrowserCapabilitiesWrapper(new HttpBrowserCapabilities 
     { 
      Capabilities = new Dictionary<string, string> 
      { 
       {"majorversion", "11"}, 
       {"MajorVersion", "11"}, 
       {"browser", "IE"}, 
       {"isMobileDevice","false"} 
      } 
     })); 

上面的代码在代码MajorVersion返回0。我也试过这个:

HttpRequest.Stub(a => a.Browser.MajorVersion).Return(11); 

这只是在安装时引发异常,说浏览器需要设置。我也尝试过与上面的HttpBrowserCapabilitiesWrapper相结合,但它仍然说浏览器需要设置。

如何在MVC中存根/模拟出Request.Browser.MajorVersion?

一些测试代码,如果有人需要它:

private BasketController sut; 
    protected HttpRequestBase HttpRequest; 

    [Test] 
    public void ShowsMajorVersionDoesNotWork() 
    { 
     // Arrange 
     HttpRequest.Stub(a => a.Browser).Return(new HttpBrowserCapabilitiesWrapper(new HttpBrowserCapabilities 
     { 
      Capabilities = new Dictionary<string, string> 
      { 
       {"majorversion", "11"}, 
       {"MajorVersion", "11"}, 
       {"browser", "IE"}, 
       {"isMobileDevice","false"} 
      } 
     })); 
     //HttpRequest.Stub(a => a.Browser.MajorVersion).Return(11); // Throws Exception 
     sut = new BasketController() 
     { 
      Url = new UrlHelper(new RequestContext(HttpContext, new RouteData()), new RouteCollection()) 
     }; 
     sut.ControllerContext = new ControllerContext(HttpContext, new RouteData(), sut); 


     // Act 
     var result = sut.Method(); 

     // Assert 
     Assert.That(result, Is.EqualTo("11")); // Fails, always returns 0 
    } 

下测试方法BasketController:

public string Method() 
    { 
     return Request.Browser.MajorVersion.ToString(); 
    } 


===========解决方案如下:

您可以创建HttpBrowserCapabilities使用BrowserCapabilitiesFactory(如解释here),使用IE11 user-agent string,并相似地,您可以使用正确的字符串嘲笑任何其他浏览器MajorVersion

public HttpRequestBase GetInterenetExplorer11StubRequest() 
{ 
    return GetBrowserCapabilitiesStub("Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko"); 
} 

public HttpRequestBase GetBrowserCapabilitiesStub(string userAgentString) 
{ 
    var browser = new HttpBrowserCapabilities 
    { 
     Capabilities = new Hashtable { { string.Empty, userAgentString } } 
    }; 
    var factory = new BrowserCapabilitiesFactory(); 
    factory.ConfigureBrowserCapabilities(new NameValueCollection(), browser); 
    var request = MockRepository.GenerateStub<HttpRequestBase>(); 
    request.Stub(a => a.Browser).Return(new HttpBrowserCapabilitiesWrapper(browser)); 
    return request; 
}
