Rails 4 sending emails in the "Test" environment

Question

Everytime I run tests, emails are actually sent. My config/environments/test.rb has this configuration

config.action_mailer.delivery_method = :test

So I thought that whenever I run test, they should not be really sent, but when I run the command

RAILS_ENV="test" rake test

The emails get sent either way. For a moment I thought that maybe I was not using the right environment. But then I deleted completely db/test.sqlite3 and immediately after I run the tests again. The file was again restored, which proves that I am actually running in the test environment.

What is going on? Why are my tests sending real mails? Could it have anything to do with the fact that I am using deliver_now on my app?

Do you have another `config.action_mailer.delivery_method` statement in your _environment.rb_ or in some of your initializers? — Roope Hakulinen, Aug 22 '15 at 16:01

You should at least be able to disable them by placing

config.action_mailer.perform_deliveries = false

in your environments/test.rb as suggested by Brent Sullivan in his answer.

Magic! Thanks! Still weird that :test did not work, but this does it :) – Enrique Moreno Tent Aug 22 '15 at 16:16

Having the line ActionMailer::Base.delivery_method = :smtp in config/environment.rb overrides ActionMailer::Base.delivery_method = :test in config/environments/test.rb.

delete that line, ActionMailer::Base.delivery_method = :smtp' from config/environment.rb and place it in config/environments/production.rb. That allows you to place ActionMailer::Base.delivery_method = :test in config/environments/test.rb and the version you want in config/environments/development.rb.

This is for Rails 6 but I thought it might help someone who is having this problem.

make sure to put the following in your config/environments/test.rb file:

  config.action_mailer.delivery_method = :test
  config.active_job.queue_adapter = :test
