获取命令测试期间发送的电子邮件的内容 [英] Get content of email sent during command tests

问题描述

在测试过程中，我调用了一些发送电子邮件的命令。我可以显示通过以下命令发送的电子邮件数量：

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')
    )
);

Symfony2文档说明了如何在网络测试过程中使用探查器获取电子邮件内容（也在Stack Overflow上对此进行了说明），但我不知道该怎么做

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.

我使用了这些链接中提供的代码：

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()
        );
    }
}

它返回此错误：

传递给Symfony\Component\HttpKernel\Profiler\Profiler :: loadProfileFromResponse（）的参数1必须是Symfony\Component\HttpFoundation的实例。 \响应，给定为空，在第72行的... / vendor / symfony / symfony / src / Symfony / Bundle / FrameworkBundle / Client.php中调用并定义
... / vendor / symfony / symfony / src /Symfony/Component/HttpKernel/Profiler/Profiler.php:81
... /供应商/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Client.php:72
... / src /ACME/MyBundle/Tests/Command/EmailTest.php:94

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

错误来自此行：

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

似乎合乎逻辑，因为没有请求，因此没有响应。

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

我使用Symfony 2.8.7。

I use Symfony 2.8.7.

这是我在<$ c $中的Swiftmailer配置c> app / config_test.yml ：

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

推荐答案

I'

// 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);

然后您可以通过以下方式获取消息内容：

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();
}
