Rspec:ActionMailer :: Base.deliveries总是为空

Leo*_*Teo 8 rspec ruby-on-rails

我写了一个RSpec集成测试.根据test.log,我可以看到它已经发送了一封电子邮件,但是当我尝试使用ActionMailer :: Base.deliveries访问该电子邮件时,它总是显示它是空的.

我已经阅读了其他类似的问题,并尝试了一切.我很难过.

以下是使用Capybara/RSpec的代码:

it "should notify owner" do

  puts "Delivery method: #{ActionMailer::Base.delivery_method.inspect}"
  # This returns: ":test", which is correct

  # Get other guests to do the review
  @review = Review.last
  share_link = "http://#{@account.subdomain}.cozimo.local:#{Capybara.server_port}/review/#{@review.slug}"

  visit(share_link)

  fill_in "email", :with => @user1.email
  fill_in "password", :with => "foobar"

  click_button "Start Review"

  # Add a comment
  click_on "ice-global-note-button"
  find(:css, "#ice-global-note-panel > textarea.ui-corner-all").set "Foo"
  click_on "ice-global-note-submit-button"

  # Test is failing here. WTF? The array should not be empty
  ActionMailer::Base.deliveries.empty?.should be_false

  # Check that a notification email was sent to the owner
  open_email(@owner.email)
  current_email.should have_content "Hi #{@owner.first_name}"

end

如上所示,config.action_mailer.delivery_method =:test

在test.log中,它显示电子邮件确实已发送!

这是使用Capybara和Selenium的集成测试.因此,您必须等待应用程序实际发送邮件,然后再检查它是否已发送邮件.

注意 - 这解决了问题,但通常是不好的做法

添加一个sleep 1告诉rspec在触发发送邮件事件后等待.然后通过检查ActionMailer :: Base.deliveries数组并传递它来恢复.

如上所述,这通常是不好的做法,因为它会减慢测试速度.

更好的方法

集成测试不应该测试邮件是否完全发送.测试应分为明确的测试课程职责.因此,我们将以不同的方式构建测试,以便我们仅测试在另一个类(控制器或资源测试)中发送的邮件.我们还可以使用期望来检查是否实际调用了mail方法,尽管我们仍然可能会遇到时间问题.

你永远不应该在规格上使用睡眠或那些耗时的方法,我只会减慢你的规格!

尝试在邮件中使用期望值,在测试开始时添加类似的内容

mail = mock(mail)
mail.should_receive(:deliver)
YourMailer.should_receive(:your_method).once.and_return(mail)

这样你就不必等待,你实际上是在测试你必须测试的内容(代码创建和传递邮件)而不是邮件程序代码(你只在邮件对象上调用传递,实际传递是一项工作的 ActionMailer 测试并且您在您的应用程序上与它无关,您应该相信调用这些方法有效)
