Rails 8 test helpers do not work with fixtures and RSpec

[Fh-Ndiritu]

I am still running into this issue even after the merge of a related fix

Environment

1. Ruby 3.4
2. Rails 8.0.2
3. Devise 4.9.4

Test setup

1. RSpec with fixtures (users.yml)
2. devise_for :users is already set in routes
3. Integration and Controller helpers are configured in rails_helper

Error on running on controller tests

   
   RuntimeError:
     Could not find a valid mapping for #<User id: ...

Solution that worked for me

Add to spec_helper

  # TODO Remove when Devise fixes https://github.com/heartcombo/devise/issues/5705
  config.before(:each, type: :controller) do
    Rails.application.reload_routes_unless_loaded
  end
end

It appears that a release including the commit that fixes this issue hasn’t been made yet.
