ruby-on-rails – Rspec：ActionMailer :: Base.deliveries总是空的

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！

解决方法

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

添加睡眠1以告诉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.
