Since we updated our application to Rails 4.2, our mailer tests seems to
fail (or not) randomly.
Simplified mailer code:
class ReservationMailer < ActionMailer::Base
default from: ‘[email protected]’,
bcc: ‘[email protected]’
def reservation_received(reservation)
@reservation = reservation
@product = reservation.product
mail to: @reservation.email,
from: '[email protected]',
subject: "Bestätigung Eingang Vormerkung für Produkt
#{@product.name}"
end
end
Simplified test code:
reservation = Reservation.new(email: '[email protected]', product:
product)
email =
ReservationMailer.reservation_received(reservation).deliver_now
assert_equal 1, ActionMailer::Base.deliveries.size
There are some more mailers very similar to this mailer and the tests
seem
to fail randomly.
That means, sometimes just one of these tests fail, sometimes two and
somewhen nothing fails.
I couldn’t figure out any problem, but maybe you can help me out
