Little trick to test and inspect the body of the mailable classes

Demo.php

<?php

//Usage:

//$token = factory(etc...);

$this->open(new TokenMail($token))
    ->seeLink($token->url, $token->url);

Instructions.md

• Add the trait InteractsWithMailable in your tests/ folder

• Autoload it with Composer:

  "autoload-dev": { "classmap": [ "tests/InteractsWithMailable.php" ] },

• Execute composer dump-autoload in the console

• Include the trait InteractsWithMailable in the classes you want to test mailables.

• Don't mix up visit() and open() since open() will overwrite the crawler.

• If Laravel tells you the array driver is not supported, please execute composer update to make sure you have the latest Laravel 5.3 version.

InteractsWithMailable.php

<?php

use Illuminate\Contracts\Mail\Mailable;
use Symfony\Component\DomCrawler\Crawler;

trait InteractsWithMailable
{
    protected function open(Mailable $mailable)
    {
        $this->app->make('config')->set('mail.driver', 'array');

        $this->mailTransport()->flush();

        $this->app->make('mailer')->send($mailable);

        $mail = $this->swiftMessages()->first();

        $this->crawler = new Crawler($mail->getBody());

        return $this;
    }

    protected function swiftMessages()
    {
        $messages = $this->mailTransport()->messages();

        $this->assertNotEmpty($messages, 'No messages were sent');

        return $messages;
    }

    protected function mailTransport()
    {
        return $this->app->make('mailer')->getSwiftMailer()->getTransport();
    }
}
