PHPUnit：获取equalTo断言以忽略属性

我有以下PHPUnit测试用例：

    $mailer = $this->getMockBuilder(MailerInterface::class)->getMock();
    $simpleMailer = new SimpleMailer($mailer);

    $message = (new Message())
        ->setTo($user)
        ->setFrom($from)
        ->setSubject($subject)
        ->setTemplate(SimpleMailer::TEMPLATE)
        ->setContext(['message' => $body]);

    if ($bcc) { $message->addBcc($bcc); }

    $mailer
        ->expects($this->once())
        ->method('send')
        ->with($this->equalTo($message));

    $simpleMailer->sendMessage($user, $subject, $body, $from, $bcc);

在更改Message类之前，此方法一直工作良好。Message类现在在构造上设置一个唯一的ID，这意味着它equalTo现在返回false，具有以下区别：

 MailerBundle\Document\Message Object (
-    'id' => '5a372f3c-a8a9-4e1e-913f-d756244c8e52'
+    'id' => '11176427-7d74-4a3c-8708-0026ae666f8b'
     'type' => null
     'user' => Tests\TestUser Object (...)
     'toName' => ''
     'toAddress' => null
     'domain' => null
     'fromName' => null
     'fromAddress' => 'user@example.org'
     'bccAddresses' => Array (...)
     'subject' => 'subject'
     'textBody' => null
     'htmlBody' => null
     'template' => 'MailerBundle:MailTemplates:...l.twig'
     'context' => Array (...)
)

有什么方法可以从相等性检查中排除某些属性？

如果您的Message类具有吸气剂，则可以在with函数中使用回调以仅匹配您关心的属性。类似于

$mailer
    ->expects($this->once())
    ->method('send')
    ->with($this->callback(function(Message $message) use ($user, $from, $subject, $body) {
            return $message->getTo() == $user 
                && $message->getFrom() == $from 
                && $message->getSubject() == $subject 
                && $message->getTemplate() == SimpleMailer::TEMPLATE
                && $message->getContext()['message'] == $body
        }));
