Is it possible to turn off ActionMailer emails whe

问题:

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:

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

  ...
  # 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']
                                           }
  ...

Thanks

回答1:

 config.action_mailer.delivery_method = :test

or

just before tests

ActionMailer::Base.delivery_method = :test
