I have plans to make email-spec work with any SMTP mailer and thereby
making it more "black-box"y and allow for external processes to be
easily tested... However, that is not done yet. As it stands now you
have two options: a) have the test execution and script in the same
process or b) Use ARMailer in your testing environment. ARMailer
places the messages in a database for queuing. So instead of checking
the in-memory array EmailSpec will check the queue on the database.
Since this is just for testing then you could use a lightweight sqlite3
db to store this.
