使用Amazon ses邮件发送时Rspec测试失败

Question

I recently switched over a rails app to send mail through amazon ses. The sending of the mail works fine, however the tests are failing around the mail items with the following error:

TypeError: can't convert Fixnum into String # (eval):3:in 'send_raw_email'

I have the test environment mail settings set properly to :test

config.action_mailer.delivery_method = :test

I can prevent the errors from happening by not sending emails, but then I get errors about the mail not being delivered.

config.action_mailer.perform_deliveries = false
should_change -> { ActionMailer::Base.deliveries.size } do
   result should have changed, but is still 0

Gem versions are below:

rails (3.2.12)
rspec (2.8.0)
cucumber (2.3.3)
aws-sdk (1.33.0)

Any suggestions on what is going on, or how to work around this. If any other info is needed let me know. This worked fine before I switched the sending of mail to use amazon ses.

EDIT:

The tests that are failing, are all that involve an email being sent using .deliver

BlahMailer.send_invite(team).deliver

This is inside a model and controller which the tests just call the associated route in the controller or call the associated function in the model. Not sure what else to show, since the error is showing its coming from send_raw_email which is the ses function, not any code from the app.

EDIT 2: More code

Here is one of the tests, in this example it sets up the factory for the model and each test.

before :each do
  subject = Factory(:ticket, action_type: 'name_change', team_name: 'test123')
end

Here is the factory in rspec

Factory.define :ticket do |ticket|
  team = nil
  ticket.team { team = Factory(:team) }
  ticket.creator { team.captain }
  ticket.subject { Factory(:team_assignment, team: team, user: Factory(:active_user)).user }
end

And then here is the code in the model around where the email is sent

%w(requested approved cancelled accepted).each do |state|
  define_method "notify_#{state}" do
    TicketMailer.send("#{action_type}_#{state}", self).deliver
  end
end

I have tried putting in straight text for basically everything having to do with the mailer, just to make sure there are no issues with that. If you need anymore of the model or the actual mailer let me know. I just really cant figure out where this is dieing. My only conclusion is its just a bug with the older versions of the aws sdk and rspec gems. I even tried replacing aws-sdk with newer versions but was still unsuccessful in getting anything else to work.

Answer 1

The problem is that you're setting config.action_mailer.perform_deliveries = false , so no deliveries are being made and therefore ActionMailer::Base.deliveries will always be an empty collection.

If you want to test email deliveries, then set config.action_mailer.perform_deliveries = true and use an interceptor to ensure you're not sending emails to users.

lass SandboxEmailInterceptor
  def self.delivering_email(message)
    recipients =
      if Rails.env.test?
        [
          "user@example.com"
        ]
      end

    message.to = recipients
    message.cc = []
  end
end

unless Rails.env.production? || Rails.env.test?
  ActionMailer::Base.register_interceptor(SandboxEmailInterceptor)
end
