Rails 3 test fixtures with carrierwave?

Question

I\'m working on upgrading from attachment_fu to carrierwave, since attachment_fu is broken in rails 3.

None of the tests are able to run, because we have invalid fixture

Answer 1

config/initializers/carrier_wave.rb

In Rails 4

# class NullStorage is defined here before the following block

if Rails.env.test?
  CarrierWave.configure do |config|
    config.storage NullStorage
  end
end

& in fixtures:

a_image:
  post_id: 1
  attachment_file: <%= File.open(Rails.root.join("test/files/test.png")) %>
