我有一個模型測試belongs_to的包括由關注
class Survey < ActiveRecord::Base
include Respondable
end
在DB 調查桌子旁邊的字段:
- responses_saved_date
- responses_saved_by_type
- responses_saved_by_id
和模塊
module Respondable
extend ActiveSupport::Concern
included do
belongs_to :responses_saved_by, :polymorphic => :true
end
def update_saved_settings!(person=nil)
self.responses_saved_date = Time.now
self.responses_saved_by = person
self.save
end
end
我嘗試寫能夠響應關注單元測試,單獨進行測試,根據這一博客帖子https://semaphoreci.com/community/tutorials/testing-mixins-in-isolation-with-minitest-and-rspec
這裏是我的RSpec:
describe Respondable do
class DummySurvey < ActiveRecord::Base
include Respondable
end
subject { DummySurvey.new }
it { should belong_to(:responses_saved_by) }
it 'saves the settings with user' do
subject.update_saved_settings!(user)
subject.responses_saved_date.should_not be_nil
subject.responses_saved_by.should eq user
end
it 'saves the settings without user' do
subject.update_saved_settings!
subject.responses_saved_date.should_not be_nil
subject.responses_saved_by.should be_nil
end
end
當我運行測試我收到下一個錯誤:
Failure/Error: subject { DummySurvey.new }
ActiveRecord::StatementInvalid:
PG::UndefinedTable: ERROR: relation "dummy_survey" does not exist
