Behat ile spool klasörünü kontrol ederek email test etmek

swiftmailer:
    disable_delivery: true
    spool:
        type: file
        path: %kernel.cache_dir%/spool

Feature: Dummy feature

  Scenario: I can test spool emails
    Given I am on "/"
    Then the "registration" mail sent to "customer@customer.com" should contain:
    """
    Registration

    Hello,

    Thank you for registering with us.
