Mocking HttpContext in .NET MVC2 using Moq
- by Richard
Hi,
This was working in MVC 1, but has broken in MVC 2. I'm mocking the HttpContext so I can test routes. The code was originally taken from Steven Sanderson's book. I've tried mocking some extra properties as suggested in this comment but it hasn't fixed it. What am I missing?
This is the start of my test code. routeData is null when this code completes.
// Arange
RouteCollection routeConfig = new RouteCollection();
MvcApplication.RegisterRoutes(routeConfig);
var mockHttpContext = makeMockHttpContext(url);
// Act
RouteData routeData = routeConfig.GetRouteData(mockHttpContext.Object);
This method creates my mock HttpContext:
private static Mock<HttpContextBase> makeMockHttpContext(String url)
{
var mockHttpContext = new Mock<System.Web.HttpContextBase>();
// Mock the request
var mockRequest = new Mock<HttpRequestBase>();
mockHttpContext.Setup(t => t.Request).Returns(mockRequest.Object);
mockRequest.Setup(t => t.AppRelativeCurrentExecutionFilePath).Returns(url);
// Tried adding these to fix in MVC2 (didn't work)
mockRequest.Setup(r => r.HttpMethod).Returns("GET");
mockRequest.Setup(r => r.Headers).Returns(new NameValueCollection());
mockRequest.Setup(r => r.Form).Returns(new NameValueCollection());
mockRequest.Setup(r => r.QueryString).Returns(new NameValueCollection());
mockRequest.Setup(r => r.Files).Returns(new Mock<HttpFileCollectionBase>().Object);
// Mock the response
var mockResponse = new Mock<HttpResponseBase>();
mockHttpContext.Setup(t => t.Response).Returns(mockResponse.Object);
mockResponse.Setup(t => t.ApplyAppPathModifier(It.IsAny<String>())).Returns<String>(t => t);
return mockHttpContext;
}
