Get content of email sent during command tests

During my tests I call some commands which send emails. I can display the number of emails sent with the following command:

$output->writeln(
    $spool->flushQueue(
        $this->getContainer()->get('swiftmailer.transport.real')
    )
);

The Symfony2 documentation explains how to get email content by using the profiler during a Web test (also explained here on Stack Overflow), but I don't know how to do the same thing when there is no Web request.

I used the code provided in these links:

<?php

namespace ACME\MyBundle\Tests\Command;

use Liip\FunctionalTestBundle\Test\WebTestCase;

class EmailTest extends WebTestCase
{
    public function tesEmailCommand()
    {
        // load data fixtures

        // http://symfony.com/doc/current/cookbook/email/testing.html
        $client = static::createClient();
        // Enable the profiler for the next request (it does nothing if the profiler is not available)
        $client->enableProfiler();

        /** @var \Symfony\Bundle\FrameworkBundle\Console\Application $application */
        // inherit from the parent class
        $application = clone $this->application;

        $application->add(new EmailCommand());
        $command = $application->find('acme:emails');
        $commandTester = new CommandTester($command);

        $commandTester->execute(array(
            'command' => 'acme:emails'
        ));

        $display = $commandTester->getDisplay();

        $this->assertContains('foo', $display);

        // http://symfony.com/doc/current/cookbook/email/testing.html
        $mailCollector = $client->getProfile()->getCollector('swiftmailer');

        // Check that an email was sent
        $this->assertEquals(1, $mailCollector->getMessageCount());

        $collectedMessages = $mailCollector->getMessages();
        $message = $collectedMessages[0];

        // Asserting email data
        $this->assertInstanceOf('Swift_Message', $message);
        $this->assertEquals(
            'You should see me from the profiler!',
            $message->getBody()
        );
    }
}

It returns this error:

Argument 1 passed to Symfony\Component\HttpKernel\Profiler\Profiler::loadProfileFromResponse() must be an instance of Symfony\Component\HttpFoundation\Response, null given, called in .../vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Client.php on line 72 and defined .../vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Profiler/Profiler.php:81 .../vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Client.php:72 .../src/ACME/MyBundle/Tests/Command/EmailTest.php:94

The error comes from this line:

$mailCollector = $client->getProfile()->getCollector('swiftmailer');

It seems logical because there is no response since there's no request.

I use Symfony 2.8.7.

Here is my Swiftmailer configuration in app/config_test.yml:

swiftmailer:
    disable_delivery: true
    delivery_address: %swiftmailer.delivery_address%

I've been able to get it working with:

// kernel
$kernel = $this->createKernel();
$kernel->boot();

// container
$container = $kernel->getContainer();

// register swiftmailer logger
$mailer = $container->get('mailer');
$logger = new \Swift_Plugins_MessageLogger();
$mailer->registerPlugin($logger);

And then you can get the message contents with:

foreach ($logger->getMessages() as $message) {
    $subject       = $message->getSubject();
    $plaintextBody = $message->getBody();
    $htmlBody      = $message->getChildren()[0]->getBody();
}

You need to register the plugin into the mailer:

$mailer = static::$container->get('swiftmailer.mailer');
$logger = new \Swift_Plugins_MessageLogger();
$mailer->registerPlugin( $logger );

Then you can loop all the messages sent and check the data you need, for instance:

foreach ( $logger->getMessages() as $message ) {
    echo sprintf( '%s%s',$message->getSubject(), Chr(10) );
    echo sprintf( '%s%s',$message->getBody(), Chr(10) );
}

The key here is having in mind that into the SwiftMail library, the file MailTransport.php dispatches the event "beforeSendPerformed". This event is listened by $logger, instance of Swift_Plugins_MessageLogger. The plugin implements Swift_Events_SendListener interface, one of the methods is getMessages, which contains the content of the messages sent. You can also check swiftmail/swiftmailer number of messages sent in your symfony functional test.

By default SwiftmailerBundle add message logger plugin

$this->getContainer()
    ->get('swiftmailer.mailer.default.plugin.messagelogger')
    ->getMessages();

You can use it in commands tests.

I didn't found a solution, instead I made my command more verbose in order to display messages explaining what has been done, which tell me indirectly what is the email content.

You can add custom channel for Monolog and send email content to log file.

In config.yml add

monolog:
    channels: ["mm"]
    handlers:
        mm:
            level:    debug
            type:     stream
            path:     "%kernel.logs_dir%/mm.log"
            channels: ["mm"]

and then in command code use:

$logger = $this->get('monolog.logger.mm');
$logger->info($emailContent);

You can 'fake' a request like so, this might help you out.

$this->getContainer()->enterScope('request');
$request = Request::create('http://yourdomain.com'));
$this->getContainer()->set('request', $request, 'request');
$this->getContainer()->get('router')->getContext()->setHost('http://yourdomain.com');

I have a function which does similar in commands where I use services where a request needs to be present.
