Question

当测试失败时，运行selenium测试的浏览器将关闭。这在尝试调试时无益。我知道我可以选择在失败时进行屏幕截图，但如果没有完整的上下文，这将无济于事。浏览器仍然可用，我可以回击并检查发生了什么。

即使断言失败或找不到元素，有没有办法让浏览器保持打开状态？

Answer 1

几周后随机想出来。

启动服务器时，最后使用-browserSessionReuse选项。这将使整个测试期间一个浏览器会话保持打开状态，而不是在失败时关闭

Answer 2

您可能在测试结束时调用selenium.stop（）。您需要注释掉该行代码并确保在测试结束时不会销毁您的selenium对象。这将使窗户保持打开状态。同样的问题已经回答here

Answer 3

关于https://stackoverflow.com/a/6904808/654026处关于-browserSessionReuse的答案，请记住，您必须处理在测试执行之间清理cookie。否则，您可能难以调试错误。

Answer 4

一个简单的解决方案是在测试setUp（）方法中将session $ stopped属性设置为true。由于该属性是私有的，我们需要使用Reflection api。

    function setUp() {

        ....

        // Set the private property $stopped of session to true, so the window is not closed on error or at the end of tests
        $myClassReflection = new \ReflectionClass( get_class( $this->prepareSession() ) );
        $secret            = $myClassReflection->getProperty( 'stopped' );
        $secret->setAccessible( true );
        $secret->setValue( $this->prepareSession(), true );

        ...
}

经过长时间的尝试创建一个相对干净的解决方法，我现在采取了非常肮脏，但非常容易的黑客攻击。 phpunit \ selenium源代码不容易覆盖，如果有用于创建Session对象的工厂，那将是很好的。我试图通过覆盖和代理对象来破解对象创建，但仍然无法使其工作。最后，我并不想花更多时间在这上面，而是走最简单，最肮脏的路径，即直接攻击PHPUnit_Extensions_Selenium2TestCase_Session和PHPUnit_Extensions_Selenium2TestCase类的代码。在PHPUnit_Extensions_Selenium2TestCase中插入了一个静态$ _instance，可用于检查是否存在测试失败情况。在PHPUnit_Extensions_Selenium2TestCase_Session中拦截了stop（）方法并查询了TestCase的状态。像魅力一样，但脏脏脏。

PHPUnit_Extensions_Selenium2TestCase：

private static $_instance;
public static function getInstance() { return self::$_instance; }
....
public function __construct($name = NULL, array $data = array(), $dataName = '')
{
    self::$_instance = $this;
    ....
}

PHPUnit_Extensions_Selenium2TestCase_Session：

public function stop()
{
    if ($this->stopped || $this->hasFailedTests()) {
        return;
    }
    ....
}

private function hasFailedTests()
{
    $status = PHPUnit_Extensions_Selenium2TestCase::getInstance()->getStatus();
    return $status == \PHPUnit_Runner_BaseTestRunner::STATUS_ERROR
    || $status == \PHPUnit_Runner_BaseTestRunner::STATUS_FAILURE;
}

这是一个更清洁的解决方案。覆盖了与会话创建相关的所有类。会话类是会话关闭的地方，因此需要覆盖stop（）方法。

TODO：添加参数来控制行为，是否以及何时打开浏览器窗口。

重写了5个类：PHPUnit_Extensions_Selenium2TestCase，PHPUnit_Extensions_Selenium2TestCase_Driver，PHPUnit_Extensions_Selenium2TestCase_Session，PHPUnit_Extensions_Selenium2TestCase_SessionStrategy_Isolated，PHPUnit_Extensions_Selenium2TestCase_SessionStrategy_Shared。创建了2个引导程序文件，1个用于共享浏览器会话，1个用于隔离的浏览器会话。显示1个示例测试。
