How to: Cleanup after your Rspec tests

If you are running tests that generate images, you can use an after(:all) callback in Rspec to do some cleaning up. The actual cleanup code will vary based on your setup, but here is an example:

RSpec.configure do |config|
  # ...
  config.after(:all) do
    # Get rid of the linked images
    if Rails.env.test? || Rails.env.cucumber?
      tmp = Factory(:brand)
      store_path = File.dirname(File.dirname(tmp.logo.url))
      temp_path = tmp.logo.cache_dir
      FileUtils.rm_rf(Dir["#{Rails.root}/public/#{store_path}/[^.]*"])
      FileUtils.rm_rf(Dir["#{temp_path}/[^.]*"])
    end
  end
end

Please Note - the above code assumes that the store_path and cache_dir paths are separated based on the Rails environment. DO NOT just copy and past that into your spec_helper file unless you understand and have accounted for that. Otherwise you may end up deleting production files too. As an example, you can configure your paths per environment as such:

class MyUploader < CarrierWave::Uploader::Base
  def cache_dir
    "#{Rails.root}/tmp/uploads/#{Rails.env}/brands/logos"
  end
  
  def store_dir
    "system/attachments/#{Rails.env}/brands/logos/#{model.friendly_id}/"
  end
end
