测试与应该匹配者和工厂女孩的性传播感染关联

Question

我在获得一个简单的STI应该匹配器规范正确通过时遇到了问题。

这是它们之间的联系。

class User < ActiveRecord::Base
end
class Provider < ActiveRecord::Base
    belongs_to :practice_manager, class_name: 'User', foreign_key: :user_id
end
class PracticeManager < User
    has_many :providers
end

. .还有我的工厂…

FactoryGirl.define do
    sequence(:email) { |n| "person#{n}@email.com" }
    sequence(:password) { |p| "thepassword123" }
    sequence(:password_confirmation) { |p| "thepassword123" }
    factory :user do
        email
        password
        password_confirmation
    end
    factory :practice_manager, parent: :user, class: 'PracticeManager' do
    end
    factory :provider_user, parent: :user, class: 'ProviderUser' do
    end
    factory :provider do
        sequence(:first_name) { |n| "Sally#{n}" }
        sequence(:last_name) { |n| "Harmon#{n}" }
        sequence(:npi) { |n| n.to_s.rjust(10, '0')}
        sequence(:sf_contact_ident) { |s| s.to_s.rjust(15, '0') }
        practice_manager
    end
end

. .还有我要通过的考试

require 'rails_helper'
RSpec.describe PracticeManager, type: :model do
    describe "Relationships" do
        it { should have_many(:providers).class_name('User').with_foreign_key(:user_id) }
    end
end

我发现的一件事是，如果我将class_name: 'User', foreign_key: :user_id添加到关联的has_many侧，我可以通过测试，但我担心这是一个假阳性。这似乎不对。

我想你把你的联想搞混了。

要在您的PracticeManager模型中测试has_many，您只需:

RSpec.describe PracticeManager, type: :model do
  describe "Relationships" do
    it { should have_many(:providers) }
  end
end

如果你想测试你的Provider模型，那么你需要额外的选项:

RSpec.describe Provider, type: :model do
  it { should belong_to(:practice_manager).class_name('User').with_foreign_key(:user_id) }
end
