phpunit、Travis-CI 和 Symfony2 - 在本地通过但在 Travis 上失败

Question

我安装了 Symfony2 (2.6)，并在通过 Travis CI 提交时运行 phpunit。目前，我只有一个测试。它只是验证主页上是否存在文本。然而，它在通过一段时间后突然在 Travis 上开始失败，我不知道为什么。

当我在本地运行 phpunit 时，基本上在除 Travis 之外的任何地方，它都会通过。

测试本身：

public function testIndex()
{
    $client = static::createClient();

    $crawler = $client->request('GET', '/');

    $this->assertTrue($crawler->filter('html:contains("Ethereal Post")')->count() > 0);
}

非常感谢任何建议。

编辑：分支并在 $crawlwer 上执行 var_dump 得到以下结果：

终于找到问题了。为了解决它，特别是针对 Symfony2/Travis，我不得不在测试中执行 var_dump($client->getResponse()->getContent()); 并让 Travis 重新运行以确定测试到底看到了什么。

看起来 Symfony2 在开发模式下运行默认情况下（意料之中）并且显示了一些在生产模式下被抑制的警告，在本地是运行。
