# Extend in your test_helper.rb or any other `/support` setup you have.
class ActiveSupport::TestCase
# === NOTICE:
# Ensure you have included `ActionMailer::TestHelper` in the test class ..
#
# This method performs any enqueued job during tests manually,
# Helpful when testing the queueing of your jobs and then the result of their execution.

# === Author: (abarrak, danielpuglisi)
#
# === returns: the result of the job execution.
#
# === example: (integration test for ActiveJob/ActionMailer)
#
# test "my action mailer" do
# post signup_url, params: @valid_params
#
# # ... other assertions ...
#
# assert_enqueued_emails 1
# assert_enqueued_jobs 1
#
# perform_last_mail_job
#
# assert_emails 1 # make sure to empty ActionMailer::Base.deliveries after each test for correct results
#
# mail = ActionMailer::Base.deliveries.last
# assert_not_nil mail
# assert_equal mail.to, [user.email]
# assert_equal mail.from, ["no-replay@example.com"]
