Unit Testing Web Services - HttpContext

Question

I want to write unit tests for a web service. I create my test project, reference my web project (not service reference, assembly reference), then write some code to test the we

You might consider taking a dependency on System.Web.Abstractions.HttpContextBase instead of using HttpContext.Current. The System.Web.Abstractions assembly has a lot of common ASP.NET Http* classes already wrapped for you. They're used all over the ASP.NET MVC code. If you're using an IoC/DI framework, it's pretty easy to use. For example, in Ninject:

Bind.ToMethod(x => new HttpContextWrapper(HttpContext.Current));

and then in your constructor...

public class SomeWebService
{
    private HttpContextBase _httpContext;

    public SomeWebService(HttpContextBase httpContext)
    {
        _httpContext = httpContext;
    }

    public void SomeOperationNeedingAuthorization()
    {
        IIdentity userIdentity = _httpContext.User.Identity;

        if (!userIdentity.IsAuthenticated)
            return;

        // Do something here...
    }
}

That's WAY oversimplified, but I hope you get the idea... As Aliostad mentioned, you can easily mock HttpContextBase using Rhino Mocks or Moq, etc. to test SomeOperationNeedingAuthorization.
