Whenever you are sending emails in integration tests using the `:test` delivery method you need to make sure that `ActionMailer::Base.deliveries` is reset after every test. This piece of boilerplate code is present in all my applications that send emails. Let's have `ActionDispatch::IntegrationTest` reset the deliveries automatically.
