当开发黄瓜测试时，是否可以关闭ActionMailer电子邮件？

问题描述

目前，我的本地开发环境设置为能够发送实际的电子邮件。因此，正在交付，并且在 ActionMailer :: Base.deliveries 表中没有保留。是否可以禁用黄瓜测试中的电子邮件发送？如果是这样，执行此操作的语法是什么？

Currently, my local development environment is setup to be able to send out actual emails. Because of this, deliveries are being made, and nothing is kept in the ActionMailer::Base.deliveries table. Is it possible to disable email sending in cucumber tests? If so, what is the syntax to do this? Or is there a better way to test emails being sent?

authentication_steps.rb：

authentication_steps.rb:

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

app / config / development.rb

app/config/development.rb

  ...
  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.perform_deliveries    = true

  # Setup for local testing of emails using gmail test account
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {  :address => 'smtp.sendgrid.net',
                                           :port => 587,
                                           :domain => ENV['MAIL_DOMAIN'],
                                           :authentication => 'plain',
                                           :enable_starttls_auto => true,
                                           :user_name => ENV['MAIL_USERNAME'],
                                           :password => ENV['MAIL_PASSWORD']
                                           }
  ...

推荐答案

 config.action_mailer.delivery_method = :test

或

ActionMailer::Base.delivery_method = :test
