/**
  * Test a URL request, returning a response object. This method is the counterpart of
  * Director::direct() that is used in functional testing. It will execute the URL given, and
  * return the result as an HTTPResponse object.
  *
  * @uses Controller::handleRequest() Handles the page logic for a Director::direct() call.
  *
  * @param string $url The URL to visit.
  * @param array $postVars The $_POST & $_FILES variables.
  * @param array|Session $session The {@link Session} object representing the current session.
  * By passing the same object to multiple  calls of Director::test(), you can simulate a persisted
  * session.
  * @param string $httpMethod The HTTP method, such as GET or POST.  It will default to POST if
  * postVars is set, GET otherwise. Overwritten by $postVars['_method'] if present.
  * @param string $body The HTTP body.
  * @param array $headers HTTP headers with key-value pairs.
  * @param array|Cookie_Backend $cookies to populate $_COOKIE.
  * @param HTTPRequest $request The {@see SS_HTTP_Request} object generated as a part of this request.
  *
  * @return HTTPResponse
  *
  * @throws HTTPResponse_Exception
