Routes are not recognized in request specs after upgrading to 2.2

I’m getting undefined local variable or method `users_path’ (as an
example) my request spec tests after upgrading to 2.2.0 from 2.1.0.

I haven’t really changed these tests from the generated code but am
curious as to why they are failing now.

require ‘spec_helper’

describe “Users” do
describe “GET /users” do
it “works! (now write some real specs)” do
get users_path

I followed the upgrade steps to regenerate spec_helper.rb (it was
identical), so I’m not sure what I am missing.
