Test mode or how to disable `gon` completely for the Test environment / Spec type?

[jibiel]

Greetings, gentlemen.

Gon never gave me any pain until last night when I decided to write specs for one of my controller concerns (simplified example):

shared_examples_for :concernable do
    describe '#meffod' do
      let(:controller) { described_class.new }

        it 'assigns a new thingie as @thingie' do
          get :new
          expect(assigns :thingie).to be_a_new Thingie
        end
      end
  end

RSpec.describe ThingiesController do
  describe 'concerns' do
    it_behaves_like :concernable
  end
end

ThingiesController
  concerns
    behaves like concernable
        #meffod
            assigns a new thingie as @thingie (FAILED - 1)

Failures:

  1) ThingiesController concerns behaves like concernable #meffod assigns a new thingie as @thingie

So the problem is with the get :new request from within shared_examples_for block. When I write get :new directly in my controller spec, everything's fine.

I also have gon callback disabled for the test environment:

before_action :gonify, unless: -> { Rails.env.test? }

or even have commented it out:

# before_action :gonify

Nevertheless it throws me the above-mentioned NoMethodError: undefined method 'uuid' for nil:NilClass. I've also tried to mock the request object, no go.

Only when I remove gon competely from my Gemfile the requests from the shared_examples_for and the controller specs are starting to show the same behavior.

So my question is do you have any workaround for the cases like this one? Probably the test mode like these thingies have:

# spec/support/geocoder.rb
Geocoder.configure lookup: :test

# spec/support/warden.rb
RSpec.configure do |config|
  config.include Warden::Test::Helpers

  config.before :suite do
    Warden.test_mode!
  end

  config.after :each do
    Warden.test_reset!
  end
end

# spec/support/omniauth.rb
OmniAuth.config.test_mode = true

I guess for now I could explicitly specify the gem for all the environment groups except :test in the Gemfile:

group :development, :staging, :production do
  gem 'gon'
end

but it would be nice to be able to disable gon completely for some types of specs while keeping it intact for the integration specs.

Thank you for Issue.

Currently, No, I do not.

It sounds good iead.

Have any workable solutions emerged on this issue?
