π¦ Code Template
Make mogera logic into the concern.
# lib/fuga/piyo.rb ( you can make it inside of the lib π)
module Fuga::Piyo
extend ActiveSupport::Concern
def mogera
# do something...
end
end
Then, include the mogera method.
# hoge.rb
class Hoge < ActiveRecord::Base
include Fuga::Piyo
end
β Testing
Write the test code for the mogera and the piyo module as shared_examples_for.
By building the model from metaprogramming, you can call the model which includes this concern from this concern test. ( The power of the metaprogramming π )
# spec/lib/fuga/piyo_spec.rb
require 'rails_helper'
shared_examples_for 'piyo' do
let(:model_name) { described_class.to_s.underscore.gsub(/\//,'_').to_sym }
let(:model) { build(model_name)}
describe 'mogera' do
# test code
end
end
Enable to load the test files.
# spec/rails_helper.rb
Dir[Rails.root.join('spec/lib/**/*.rb')].each { |f| require f }
Include it via rails_helper and test it at it behaves_like.
# spec/hoge_spec.rb
require 'rails_helper'
describe V3::ContactRequest do
# I recommend to split this test from others to test it isolated. ( `rspec spec/hoge_spec.rb -e 'includes'`
describe 'includes' do
it_behaves_like 'piyo'
end
end
Then, test it.
bundle exec rspec spec/hoge_spec.rb -e 'includes'
In this way, you can test this concern at each model which includes the concern.
