My system sends a couple of important emails. What is the best way to unit test that?
I see you can put it in pretend mode and it goes in the log. Is there something to check that?
There are two options.
Option 1 - Mock the mail facade to test the mail is being sent. Something like this would work:
$mock = Mockery::mock('Swift_Mailer');
$this->app['mailer']->setSwiftMailer($mock);
$mock->shouldReceive('send')->once()
->andReturnUsing(function($msg) {
$this->assertEquals('My subject', $msg->getSubject());
$this->assertEquals('[email protected]', $msg->getTo());
$this->assertContains('Some string', $msg->getBody());
});
Option 2 is much easier - it is to test the actual SMTP using MailCatcher.me. Basically you can send SMTP emails, and 'test' the email that is actually sent. Laracasts has a great lesson on how to use it as part of your Laravel testing here.
