PhpUnit测试 - 断言变量和树枝模板内容

标签: php symfony phpunit swiftmailer

我已根据本教程定义了一个简单的电子邮件控制器:

https://symfony.com/doc/3.4/email.html

所以php文件代码是:

<?php

namespace AppBundle\Controller;

use Symfony\Component\HttpKernel\Tests\Controller;


class SendEmailController extends Controller
{
    public function indexAction($originlEmail, $destinationEmail1, $destinationEmail2, $name, \Swift_Mailer $mailer)
    {
        $message = (new \Swift_Message('Email Title'))
            ->setFrom($originlEmail)
            ->setTo($destinationEmail1, $destinationEmail2)
            ->setBody(
                $this->renderView(
                    'emails/send-email.html.twig',
                    array('name' => $name)
                ),
                'text/html'
            );

        $mailer->send($message);

        return $this->render(...);
    }
}

.twig模板代码是:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8" />
</head>
<body>
    <h3>This is an email!</h3>
    <p>Hi {{ name }}, this is an email! </p>
</body>
</html>

现在,按照本教程https://symfony.com/doc/3.4/email/testing.html,我创建了一个PhpUnit测试类:

<?php

namespace tests\AppBundle\Controller;

use AppBundle\Controller\SendMyEmailController;

class SendCustomerEmailControllerTest extends PHPUnit_Framework_TestCase
{
    public function testMailIsSentAndContentIsCorrect()
    {
        $client = static:: createClient();

        $client->enableProfiler();

        $crawler = $client->request('POST', 'path/to/above/action');

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

        $this->assertSame(1, $mailCollector->getMessageCount());

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

        $this->assertInstanceOf('Swift_Message', $message);
        $this->assertSame('My Email Title', $message->getSubject());
        $this->assertSame($originEmail, key($message->getFrom()));
        $this->assertSame($destinationEmail1, $destinationEmail2, key($message->getTo()));
        ##Asserting template content???
        $this->assertSame(?????, $message->getBody()
        );
    }
}

然后,我遇到的问题是:

  1. 我应该在哪里以及如何定义(在测试中)变量,如$ originEmail,假设在“assertSame ...”行中,我得到错误“Undefined variable” $ originEmail”。

  2. $this->assertSame($destinationEmail1, $destinationEmail2, key($message->getTo()));的语法是否正确(考虑到多个变量)?

  3. 如何断言正文内容,如果不是.php控制器中的已定义文本,则会在 .twig模板中显示(在另外,使用像{{name}}?

  4. 这样的变量

1 个答案:

答案 0 :(得分:0)

关于1)

我将如何进行此操作取决于此信息如何传递到操作中。如果它不是请求的一部分,我会通过执行以下操作来声明预期值:

$this->assertSame('expected@email.com', $message->getFrom());

如果它是路线的一部分,我会在测试中分配一个局部变量,然后将其传递给路线,可能是这样的:

$originalEmail = 'expected@email.com';
$path = sprintf('/path/to/action/%s', $originalEmail);
$client->request('POST', $path);
...
$this->assertSame($originalEmail, $message->getFrom());

如果它是POST数据的一部分:

$data = [
    'originalEmail' => 'expected@email.com',
];
$client->request('POST', '/path/to/action', $data);
...
$this->assertSame($data['originalEmail'], $message->getFrom());

关于2)

这不会按预期工作,但你可以这样做(如果电子邮件是数组中的值):

$this->assertContains($destinationEmail1, $message->getTo());

或者像这样,如果它是一把钥匙(就像你的例子中那样):

$this->assertArrayHasKey($destinationEmail1, $message->getTo());

关于3)

如果要比较正文与示例相匹配,则可能需要将参考输出存储在文件中,然后比较内容:

$this->assertSame(
    file_get_contents(__DIR__ . '/emails/reference_output.html'),
    $message->getBody()
);

在这种情况下,您必须小心您的电子邮件正文包含与参考输出相同的名称。

或者您也可以使用crawler查看某些html元素及其内容,例如检查标题<h3>This is an email!</h3>是否在那里:

$crawler = $client->request('POST', '/path/to/action');

$this->assertSame(
    'This is an email!',
    $crawler->filter('h3')->first()->text()
);
// alternative:
$this->assertGreaterThan(
    0,
    $crawler->filter('h3:contains("This is an email!")')->count()
);
