[Zope-dev] zope.sendmail and testing

[Adam GROSZER]

Hello,

I'd rather use a mailer stub for testing.
Like the one in zope.sendmail.tests.test_mailer.py

...
class SMTP(object):
...

Something like this can be setup for individual tests with

  <utility
      name="mailer-name"
      provides="zope.sendmail.interfaces.IMailer"
      factory="your.own.mailerFactory"
      />

def mailerFactory():
    mailer = SMTPMailer()
    mailer.smtp = SMTP
    return mailer
