I am trying to unit test the following method with Moq, but I am running into issues with the accessibility of manipulating some properties on these classes, and even mocking them up for that matter.
public string GetClientIpAddress(HttpRequestMessage request)
{
if (request.Properties.ContainsKey("MS_HttpContext"))
return ((HttpContextWrapper)request.Properties["MS_HttpContext"]).Request.UserHostAddress;
if (request.Properties.ContainsKey(RemoteEndpointMessageProperty.Name))
return ((RemoteEndpointMessageProperty)request.Properties[RemoteEndpointMessageProperty.Name]).Address;
return "IP Address Unavailable";
}
In order to test, I have created an instance of HttpRequestMessage that I am passing in as a parameter. I am then adding a mock of HttpRequest and HttpContext, like so...
// Assign
var mockHttpRequestBase = new Mock<HttpRequest>();
mockHttpRequestBase.Setup(m => m.UserHostAddress).Returns("127.0.0.1");
var mockHttpContext = new Mock<HttpContext>();
mockHttpContext.Setup(m => m.Request).Returns(mockHttpRequestBase.Object);
var httpRequestMessage = new HttpRequestMessage();
httpRequestMessage.Properties.Add(new KeyValuePair<string, object>("MS_HttpContext", mockHttpRequestBase.Object));
var apiCachedController = new ApiCachedController();
// Act
var address = apiCachedController.GetClientIpAddress(httpRequestMessage);
// Assert
Assert.AreEqual(address, "127.0.0.1");
EDIT: Sorry for not being clearer on the specific problem(s) I'm having. HttpRequest is unable to be mocked. I get a NotSupportedException that "type to mock must be an interface or an abstract or non-sealed class." I've tried using HttpRequestBase and HttpContextWrapper in place of HttpRequest and HttpContext, respectively, but I receive an InvalidCastException stating, "Unable to cast object of type 'Castle.Proxies.HttpRequestBaseProxy' to type 'System.Web.HttpContextWrapper'."
