Set RAILS_ENV=test/RACK_ENV=test in Queue Mode

[3v0k4]

We want to make Queue Mode as easy as changing

bundle exec knapsack_pro:RUNNER

to

bundle exec knapsack_pro:queue:RUNNER

This PR removes the need to set RAILS_ENV=test like

RAILS_ENV=test bundle exec knapsack_pro:queue:RUNNER

---

I tried to set RAILS_ENV=test and RACK_ENV=test in two different places

• right before calling the runner in the rake file
• in the runner

but I got some (strange) errors when running bin/knapsack_pro_all.

In particular, the following error popped out to me (to reproduce remove RAILS_ENV=test \ from bin/knapsack_pro_queue_minitest and run bin/knapsack_pro_queue_minitest):

Error:
ArticlesControllerTest#test_should_get_index:
RuntimeError: Neutered Exception NoMethodError: assigns has been extracted to a gem. To continue using it,
        add `gem 'rails-controller-testing'` to your Gemfile.
    test/controllers/articles_controller_test.rb:11:in `block in <class:ArticlesControllerTest>'

The rails-controller-testing gem is in the test group, which made me think the app needs to be loaded WITH RAILS_ENV=test. So I decided to try by shelling out to a separate process by using sh. That did the trick and bin/knapsack_pro_all passes.

I believe no cassettes at all should be recorded when the domain is fake. You could kill your http server running on 3000 port before you run tests.

I researched more why

When invoking bundle exec rake knapsack_pro:... this is the call order:

• rake (in application.rb) loads the Rakefile
• the Rakefile requires config/application.rb
• config/application.rb calls Bundler.require(*Rails.groups)
• Rails.groups returns [:default, :development] so the the test gems are not required

We are good to remove comments now since we establish solution with $PROGRAM_NAME.

I think we are good to release it.
