Rails - How do you test ActionMailer sent a specific email in tests
Currently in my tests I do something like this to test if an email is queued to be sent
assert_difference('ActionMailer::Base.deliveries.size', 1) do
get :create_from_spreedly, {:user_id => @logged_in_user.id}
end
but if i a controller action can send two different emails i.e. one to the user if sign up goes fine or a notification to admin if something went wrong - how can i test which one actually got sent. The code above would pass regardless.
Answer
As of rails 3 ActionMailer::Base.deliveries is an array of Mail::Message's. From the mail documentation:
# mail['from'] = '[email protected]'
# mail[:to] = '[email protected]'
# mail.subject 'This is a test email'
# mail.body = 'This is a body'
#
# mail.to_s #=> "From: [email protected]\r\nTo: you@...
From that it should be easy to test your mail's in an integration
mail = ActionMailer::Base.deliveries.last
assert_equal '[email protected]', mail['from'].to_s
assert_equal '[email protected]', mail['to'].to_s
