I\'m working with mails, and names and subjects sometimes come q-encoded, like this:

=?UTF-8?Q?J=2E_Pablo_Fern=C3=A1ndez?=

Answer 1

This might help anyone wanting to test an email. delivery.html_part is normally encoded, but can be decoded to a straight HTML body using .decoded.

test "email test" do
  UserMailer.confirm_email(user).deliver_now
  assert_equal 1, ActionMailer::Base.deliveries.size
  delivery = ActionMailer::Base.deliveries.last
  assert_equal "Please confirm your email", delivery.subject
  assert delivery.html_part.decoded =~ /Click the link below to confirm your email/ # DECODING HERE
end
