How to test a controller mapped to a non-canonical path?

[Gioele Barabucci]

I have a controller `SuperPower` that is responsible for the paths under
`/super-power`, and not the canonical `/super_power` (notice the hyphen
instead of the underscore).

In my `routes.rb` I have

resources 'super-power', as :super_power

My `super_power_test.rb` contains

class SuperPowerControllerTest < ActionController::TestCase
test "shows all available" do
get :index

assert_not_nil assign(:powers)
end
end

and the test fails with

# Running tests:

[1/1] SuperPowerControllerTest#test_shows_all_available = 0.08 s
1) Error:
test_shows_all_available(SuperPowerControllerTest):
ActionController::RoutingError: No route matches
{:controller=>"super_power"}

The test fails because it doesn't use the correct path `/super-power`
but uses the canonical `/super_power`.

Is there a way to associate the tests of a controller to a certain path?
Is there a way to make this change for all the tests?
