Mock httpcontext.current.request.files

I am implementing nUnit Test case for one of my method called, UploadFile(), some thing like below

 public void UploadFile(string siteId, string sitePageId)
 {
    int fileCount = HttpContext.Current.Request.Files.Count;

    //Rest of code
 }

so basically i am reading file using HttpContext.Current.Request.Files. From UI it is working fine but when i am implementing nUnit test case for it, i am not able to mock HttpContext.Current.Request.Files. I googled about some of mocking tools but there also i didn't get anything related to mocking of HttpContext.Current.Request.Files. Please help me how to mock it or write test case for my method.

You could use dependency injection and then inject an instance of HttpContextBase into the class. Supposing you're using MVC:

public class MyController : Controller
{

    HttpContextBase _context;        

    public MyController(HttpContextBase context)
    {
        _context = context
    }

    public void UploadFile(string siteId, string sitePageId)
    {
        int fileCount = _context.Request.Files.Count;

        //Rest of code
    }
}

Now you can instantiate the controller with a mock of HttpContextBase. This is how you would do it with Moq:

[Test]
public void File_upload_test()
{
    var contextmock = new Mock<HttpContextBase>();
    // Set up the mock here
    var mycontroller = new MyController(contextmock.Object);
    // test here
}
