为什么电子邮件没有进入ActionMailer :: Base.deliveries表？

Question

目前在我的开发环境中,使用后我没有看到ActionMailer::Base.deliveries表中的任何内容mail.我缺少一个设置吗？

config/environments/development.rb :
config.action_mailer.delivery_method = :test.

应用程序/邮寄者/ notifier.rb

def send_email(user)
  mail(:to => user.email, :subject => "Welcome to our website!")
end

这些是我正在运行的测试:

When /^I signup$/ do
  visit signup_path
  @user = FactoryGirl.build(:user)
  fill_in "user_email", :with => @user.email
  fill_in "user_password", :with => @user.password
  click_button "Join now"
end

Then /^I should receive a confirmation email$/ do
  email = ActionMailer::Base.deliveries.last
  email.subject.should == "Welcome to our website!"
end

现在我得到以下错误I should receive a confirmation email: undefined method subject for nil:NilClass (NoMethodError)

谢谢!

Answer 1

另一种可能是在config/environments/test.rb中你有

config.action_mailer.delivery_method = :test

但你已经设定好了

config.action_mailer.perform_deliveries = false

所以改为

config.action_mailer.perform_deliveries = true

在我的情况下让它再次起作用.
