devise-async & sidekiq - RSpec 集成规范失败

Question

我为我的应用程序的基于设计的身份验证编写了以下集成测试：

# password_resets_spec.rb

require 'spec_helper'

describe "PasswordResets" do
  it "emails user when requesting password reset" do
    user = FactoryGirl.create(:user)
    reset_email # or else we'll have the confirmation email in the last assertion
    visit new_user_session_path
    click_link "password"
    fill_in "Email", with: user.email
    click_button "Send"
    current_path.should eq(new_user_session_path)
    page.should have_content "Will receive"
    last_email.to.should include(user.email)
  end

  it "doesn't email invalid user when requesting password reset" do
    user = FactoryGirl.create(:user)
    reset_email # or else we'll have the confirmation email in the last assertion
    visit new_user_session_path
    click_link "password"
    fill_in "Email", with: 'nobody@example.com'
    click_button "Send"
    current_path.should eq(user_password_path)
    page.should have_content "correct"
    last_email.should be_nil
  end
end

和：

# registers_spec.rb

require 'spec_helper'

describe "Registers" do
  it "should inform the user to confirm account" do
    user = FactoryGirl.build(:user)
    visit new_user_registration_path
    fill_in "Username", with: user.username
    fill_in "Email", with: user.email
    fill_in "Password", with: user.password
    fill_in "Confirm password", with: user.password
    click_button "Send"
    current_path.should eq(root_path)
    page.should have_content "You have been sent"
    last_email.to.should include(user.email)
  end
end

我将 Sidekiq 用于后台作业，last_email 和 reset_email 来自以下模块：

module MailerMacros
  def last_email
    ActionMailer::Base.deliveries.last
  end

  def reset_email
    ActionMailer::Base.deliveries.clear
  end
end

在 User 模型上停用 devise-async 时，所有这三个规范都可以正常工作。当我打开它时，密码重置规范运行正常，但寄存器抱怨 last_email 为零，我不明白为什么。与密码重置邮件相比，发送的确认邮件是否有所不同？

请注意，我的 spec_helper.rb 文件中有 require 'sidekiq/testing/inline' 行，以便立即完成电子邮件发送，并且为我的测试环境设置了 config.action_mailer.delivery_method = :test，因此不会发生实际的电子邮件发送。

Answer 1

我已经用 mhfs 的help 解决了这个问题。问题是我在spec_helper.rb 中将config.use_transactional_fixtures 设置为true，因此用户是在事务中创建的，并且从未调用过发送电子邮件的after_commit 挂钩。密码重置显然没有在事务中运行，这就是它们起作用的原因。

所以我不得不关闭 use_transactional_fixtures 并使用 database_cleaner 来保持我的数据库整洁。

这是我必须修改的：

将gem 'database_cleaner' 添加到我的Gemfile。

明显修改spec_helper.rb:

config.use_transactional_fixtures = false

将以下内容添加到spec_helper.rb：

config.before(:each) do
  with_transaction_callbacks = example.metadata[:with_transaction_callbacks]
  if with_transaction_callbacks
    DatabaseCleaner.strategy = :truncation
  else
    DatabaseCleaner.strategy = :transaction
  end
  DatabaseCleaner.start
end

config.after(:each) do
  DatabaseCleaner.clean
end

最后重做我在registers_spec.rb 中的块以阅读：

describe "Registers" do
  it "should inform the user to confirm account", with_transaction_callbacks: true do
    [ --- 8< snip --- ]
  end
end

魔法发生在第二行。
