问题
I've got a mailer sending through a GMail account, and I want to test that ActionMailer can actually log in to GMail's SMTP server with the credentials I've given it. What's the best way to test this?
回答1:
It's not a full-stack solution, but you can check that the server authentication happens correctly by using Net::SMTP directly. The Mail gem that Rails 3 uses to send ActionMailer emails uses Mail like so (with your ActionMailer.smtp_settings):
#line 96 of mail-2.2.7/lib/mail/network/delivery_methods/smtp.rb
smtp = Net::SMTP.new(settings[:address], settings[:port])
if settings[:enable_starttls_auto]
smtp.enable_starttls_auto if smtp.respond_to?(:enable_starttls_auto)
end
smtp.start(settings[:domain], settings[:user_name], settings[:password],
settings[:authentication]) do |smtp|
smtp.sendmail(message, envelope_from, destinations)
# @Mason: this line need not be included in your code. SMTP#start throws
# a Net::SMTPAuthenticationError if the authentication was not successful.
# So just putting this call to #start with an empty block in a method and
# calling assert_no_raise Net::SMTPAuthenticationError should do the trick.
# The empty block is necessary so that the connection gets closed.
# Reference #{rubydir}/lib/ruby/1.8/net/smtp.rb for more info.
end
Looks like ActionMailer::Base.smtp_settings is accessible too:
settings = ActionMailer::Base.smtp_settings
Putting that in your test and commenting out the line spoken of above should have a working example for you.
回答2:
smtp = Net::SMTP.new settings[:address], settings[:port]
smtp.enable_starttls_auto if settings[:enable_starttls_auto]
smtp.start(settings[:domain]) do
expect {
smtp.authenticate settings[:user_name], settings[:password], settings[:authentication]
}.to_not raise_error
end
Calling authenticate
will raise a Net::SMTPAuthenticationError
if the authentication fails.
Otherwise, it will return a Net::SMTP::Response
, and calling status
on the response will return "235"
.
