devise-async & sidekiq - RSpec集成规范失败

Question

我为我的应用程序的基于Devise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

我使用Sidekiq进行后台作业，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

当在用户模型上禁用devise-async时，所有这三个规范都工作得很好。当我打开它时，密码重置规范运行正常，但是寄存器1抱怨last_email为空，我不明白为什么。发送的确认邮件与密码重置邮件有什么不同吗？

请注意，我在spec_helper.rb文件中使用了require 'sidekiq/testing/inline'行，以便即时完成电子邮件发送，并为我的测试环境设置了config.action_mailer.delivery_method = :test，以便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，发送电子邮件的after_commit钩子从未被调用过。密码重置显然不会在事务内部运行，这就是它们起作用的原因。

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

下面是我需要修改的内容：

在我的Gemfile中添加gem 'database_cleaner'。

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，在registers_spec.rb中重做我的代码块以读取：

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

魔术发生在第二行。
