I want to test my registration process locally (development mode), how can I test how emails will be sent out and rendered etc?

I am not referring to a unit-test or integration test, but just while developing my app and going on the register page etc. I want it to send out the emails but to a file not using smtp.

Is this possible?

What options do I have?

This is configurable in the config/environments/*.rb files.

# output to tmp/mails directory
config.action_mailer.delivery_method = :file
# ... and to specify output location
# config.action_mailer.file_settings = { :location => Rails.root.join('tmp/mail') }

Detailed information can be found in the config section of Action Mailer Basics or on ActionMailer::Base API

Rails 4.2 :file delivery method source and Mail::FileDelivery source

LetterOpener makes it even simpler for you to preview the emails you just sent by opening the file in the browser automatically (in development environment of course).

  • not working for me on Rails 4. I wish their Readme had more info or pointed towards a tutorial for rails 4. seems like a cool thing but the documentation for new users is not great – cwd Sep 25 '14 at 19:57

    works for one-off testing that an email was sent, yet I might recommend [mailcatcher](https://github.com/sj26/mailcatcher#rvm) for long-term testing – Jake Berger Feb 04 '15 at 11:35

I realize you said you want to check emails in the context of manual testing, but it seems worth mentioning that these sorts of tests can be automated. email_spec is one gem i've used to do it.
