Mock HttpContext.Current in Test Init Method

by

HttpContext.Current returns an instance of System.Web.HttpContext, which does not extend System.Web.HttpContextBase. HttpContextBase was added later to address HttpContext being difficult to mock. The two classes are basically unrelated (HttpContextWrapper is used as an adapter between them).

Fortunately, HttpContext itself is fakeable just enough for you do replace the IPrincipal (User) and IIdentity.

The following code runs as expected, even in a console application:

HttpContext.Current = new HttpContext(
    new HttpRequest("", "http://tempuri.org", ""),
    new HttpResponse(new StringWriter())
    );

// User is logged in
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity("username"),
    new string[0]
    );

// User is logged out
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity(String.Empty),
    new string[0]
    );
