Common controller action to run from a single file using Rspec

[Arup Rakshit]

Hi,

I have very similar index action test pattern in 100+ controllers. That is why I am thinking to run them from a single file. Here is my code to meet the same need :

require 'spec_helper'

Dir[Rails.root.join('app','admin', '**', '*')].each do | file_name |
  admin_controller = File.basename(file_name, '.rb')

  RSpec.describe "Admin::#{ admin_controller.classify }sController".constantize, type: :controller do
    render_views

    let(:login_with) { create(:full_admin_user) }

    login_admin_user

    include_examples "index"
  end
end

But, once I run it, getting below error :

/Users/arup/.rvm/gems/ruby-2.2.3@admin/gems/activesupport-4.2.5/lib/active_support/inflector/methods.rb:263:in `const_get': uninitialized constant Admin::AccountingsController (NameError)
	from /Users/arup/.rvm/gems/ruby-2.2.3@admin/gems/activesupport-4.2.5/lib/active_support/inflector/methods.rb:263:in `block in constantize'
	from /Users/arup/.rvm/gems/ruby-2.2.3@admin/gems/activesupport-4.2.5/lib/active_support/inflector/methods.rb:259:in `each'
	from /Users/arup/.rvm/gems/ruby-2.2.3@admin/gems/activesupport-4.2.5/lib/active_support/inflector/methods.rb:259:in `inject'
	from /Users/arup/.rvm/gems/ruby-2.2.3@admin/gems/activesupport-4.2.5/lib/active_support/inflector/methods.rb:259:in `constantize'
	from /Users/arup/.rvm/gems/ruby-2.2.3@admin/gems/activesupport-4.2.5/lib/active_support/core_ext/string/inflections.rb:66:in `constantize'
	from /Users/arup/eligible/admin/spec/controllers/controller_index_action_spec.rb:7:in `block in <top (required)>'
	from /Users/arup/eligible/admin/spec/controllers/controller_index_action_spec.rb:4:in `each'
	from /Users/arup/eligible/admin/spec/controllers/controller_index_action_spec.rb:4:in `<top (required)>'

Those test are for ActiveAdmin controllers. When I run the same test as below :

require 'spec_helper'

RSpec.describe Admin::AccountingsController, type: :controller do
  render_views

  let(:full_admin_user) { create(:full_admin_user) }
  let(:login_with) { full_admin_user }

  login_admin_user

  include_examples "index"
end


It works like a charm. Now my question is why the code given at top of this thread didn't work ?

Try requiring the files manually, Rails autoloading is sometimes a bit funny.
