Testing delayed_job

Preparation

1. Start Postgres and create the database:

   brew services start postgresql
   createdb delayed-job-test

2. Configure the database connection:

   export DB=postgres:///delayed-job-test

3. Run migrations:

   sequel -m db/migrations $DB

4. Start the job processing daemon:

   ./scripts/process-jobs run

On a Happy Day

1. Provide the mail body on STDIN and the email addresses as parameters:

   echo "Dear number $RANDOM, you are an awesome number! Best regards; The Computer." | ./scripts/enqueue-job foo@example.com bar@example.org

   Here, we are sending a letter to foo@example.com and bar@example.org, each as a single job.

2. Verify that the mailer ran (we simulate it by appending to a 'queue' file):

   tail -f log/mail.queue

   Additional details about the job itself can be found in log/delayed_job.log.
