According to a comment in this rails bug, the proper place is in a functional test. If you try to test them in an integration test, the routes you established in routes.rb will not be available.

require 'test_helper'

class FooControllerTest < ActionController::TestCase
  test "foo routes" do
    assert_recognizes({:controller => 'foo_controller', :action => 'list'}, '/foos'
  end
end

Route tests are good places to list links that exist in the wild, and avoid inadvertently breaking them with a code change. It's a little strange that the tests are scoped to a controller, since it's the route set as a whole you're actually testing, but I haven't heard of a 'route set test'.
