request.fullpath with RSpec - ruby-on-rails

Question

In my application controller, I have a couple of methods defined as follows:
def store_location
session[:return_to] = request.fullpath
end
def redirect_back_or_default(default)
# make sure this method doesn't redirect back to the current page
if session[:return_to] == request.fullpath
redirect_to default
else
redirect_to(session[:return_to] || default)
end
session[:return_to] = nil
end
In order to test these methods, I need to find some way to set request.fullpath in RSpec. Does anybody know how I can accomplish this?
Update
When testing these methods, I'm using a shared example group, like so:
shared_examples_for "redirect back or default" do
it "should redirect" do
request
response.should be_redirect
end
describe "when the user has a back page" do
it "should redirect to back"
end
describe "when the user does not have a back page" do
it "should redirect to default" do
request
response.should redirect_to(default_path)
end
end
end
When including the shared example groups, I do something like the following:
before(:each) do
def request
post :create, :user => #attr
end
def default_path
:root
end
end
include_examples "redirect back or default"
Thus, when a method use redirect_back_or_default, I just have to add the above code to its tests and I'm done.In this way, I can still be specific about testing redirect_back_or_default without having to test against the implementation, which seems like a better way to do BDD to me.

You have access to a #request object that you might be able to set directly, like:
#request.fullpath = "/my/path"
My guess is that will be overridden when you make your actual get/post/put/delete, however, in the controller spec.
Any reason you want to set fullpath directly rather than knowing fullpath will just be something simple like "/mock"?
class MocksController < ApplicationController
def show
end
end
describe MocksController do
before do
MyApp::Application.routes.draw do
resource :mock, :only => [:show]
end
end
after do
Rails.application.reload_routes!
end
it "something" do
get :show
should # something
end
end
