The ActionMailer in my Rails 3.1 project has an odd behavior, the
ActionMailer::Base.deliveries is empty in test while I can actually
receive the email by running the code in rails console. Anybody can
points out what wrong it is?
spec/mailers/user_mailer_spec.rb
require “spec_helper”
describe UserMailer do
describe “.reminding_email” do
subject { UserMailer.reminding_email(user).deliver }
let(:user) { create :confirmed_user_with_mass_tasks }
it “should be delivered” do
ActionMailer::Base.deliveries.should_not be_empty
end
its(:to) { should == [user.email] }
its(:subject) { should == “Task Reminding” }
end
end
app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
layout “email”
default from: Rails.env.production? ? “@gmail.com” :
“@gmail.com”
def reminding_email(user)
@tasks = user.tasks.reminding_required
@current = Time.current
mail(to: user.email, subject: “Task Reminding”)
end
end

The test environment is used exclusively to run your application’s
test suite. You never need to work with it otherwise. Remember
that
your test database is “scratch space” for the test suite and is
wiped
and recreated between test runs. Don’t rely on the data there!
config.cache_classes = true
Configure static asset server for tests with Cache-Control for
performance
config.serve_static_assets = true
config.static_cache_control = “public, max-age=3600”
Log error messages when you accidentally call methods on nil
config.whiny_nils = true
Show full error reports and disable caching
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
Raise exceptions instead of rendering exception templates
config.action_dispatch.show_exceptions = false
Disable request forgery protection in test environment
config.action_controller.allow_forgery_protection = false
Tell Action Mailer not to deliver emails to the real world.
The :test delivery method accumulates sent emails in the
ActionMailer::Base.deliveries array.
config.action_mailer.delivery_method = :test
Use SQL instead of Active Record’s schema dumper when creating the
test database.
This is necessary if your schema can’t be completely dumped by the
schema dumper,
like if you have constraints or database-specific column types
config.active_record.schema_format = :sql
Print deprecation notices to the stderr
config.active_support.deprecation = :stderr
Setup default URL options as devise needed
config.action_mailer.default_url_options = { :host => ‘localhost:3000’
}
end

Pick the frameworks you want:
require “active_record/railtie”

require “action_mailer/railtie”
require “active_resource/railtie”

if defined?(Bundler)
If you precompile assets before deploying to production, use this
line
Bundler.require(*Rails.groups(:assets => %w(development test)))
Bundler.require *Rails.groups(:assets) if defined?(Bundler)
If you want your assets lazily compiled in production, use this line
Bundler.require(:default, :assets, Rails.env)
end
