如何使用PHPUnit测试mail（）

Question

is there a way to test with PHPUnit (or maybe other testing framework for PHP) if mail is sent correctly? I have to test a code which uses PHP function mail() . With custom mailer class i could always make a mock, but for mail() ... ? Maybe there is some plugin which is capable to use IMAP and verify if mail is received? (and it should be OS-agnostic if it is possible...)

Answer 1

If you want to check whether or not mail was sent successfully, you don't need phpunit, you simply do:

mail(.....) or die('Could not send the email !!');

Or

if (!mail(......)){
  echo 'Could not send the email !!';
}

Note that this tells you whether or not mail was sent NOT whether or not it was received to whom the email was sent. So the better term here should be delivered.
