Behat工作正常，但PhantomJS在尝试点击时在下拉菜单上失败

Question

下面的Gherkin可以正常使用但是当我使用PhantomJS时，我在When I follow "Profile"行下面会出错：

注意：该元素是bootstrap的下拉菜单，因此在单击后切换。

错误：

Exception thrown by (//html/.//a[./@href][(((./@id = 'Profile' or contains(normalize-space(string(.)), 'Profile')) or contains(./@title, 'Profile') or contains(./@rel, 'Profile')) or .//img[contains(./@alt, 'Profile')])] | .//*[./@role = 'link'][((./@id = 'Profile' or contains(./@value, 'Profile')) or contains(./@title, 'Profile') or contains(normalize-space(string(.)), 'Profile'))])[1]

小黄瓜：

When I follow "Profile"
And I follow "Edit"

HTML：

<ul class="nav navbar-nav navbar-right">
    <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Profile <span class="caret"></span></a>
        <ul class="dropdown-menu" role="menu">
            <li><a href="#">Show</a></li>
            <li><a href="#">Edit</a></li>
        </ul>
    </li>
</ul>

我已经发现了原因并通过如下所示的小修复解决了。

使用Bootstrap时，菜单会被压扁，只显示一个图标代表相同的菜单，这是响应式设计的正常行为。一切都很好，但是当PhantomJS运行时，它找不到它正在寻找的文本。例如我个案中的“个人资料”菜单。

菜单的原始状态，总是正常工作：

压扁版本后导致PhantomJS失败：

<强> SOLUTION：

只需将窗口大小设置为更大的值，以便在测试时不会压缩菜单。您可以根据需要将屏幕尺寸从1024X768更改为其他内容。

#symfony/src/Site/CommonBundle/Features/Context/FeatureContext.php

/**
 * @BeforeStep
 */
public function beforeStep()
{
    $this->getSession()->resizeWindow(1024, 768, 'current');
}
