phpunit；php-webdriver共享一个webdriver实例 - phpunit & php-webdriver sharing a webdriver instance

我正试图弄清楚如何在多个php单元测试中共享一个php web驱动程序实例。该实例在第一次测试中运行良好，但到了第二次测试时，驱动程序执行器的curl资源已经丢失。

setup-webdriver.hp:

<?php
namespace Facebook'WebDriver;
use Facebook'WebDriver'Remote'DesiredCapabilities;
use Facebook'WebDriver'Remote'RemoteWebDriver;
require_once('php-webdriver-community/vendor/autoload.php');
$host = 'http://localhost:4444/wd/hub';
$capabilities = DesiredCapabilities::firefox();
$driver = RemoteWebDriver::create($host, $capabilities, 5000);

tests/GoogleTest.php：

<?php
class GoogleTest extends PHPUnit_Framework_TestCase {
    public function testGoogleTitle() {
        global $driver;
        print_r($driver);
        $driver->get('http://www.google.com/');
        echo $driver->getTitle();
    }
}

tests/YahooTest.php：

<?php
class YahooTest extends PHPUnit_Framework_TestCase {
    public function testYahooTitle()
    {
        global $driver;
        print_r($driver);
        $driver->get('http://www.yahoo.com/');
        echo $driver->getTitle();
    }
}

我正在通过/opt/local/bin/php56 /usr/local/bin/phpunit-5.1 --bootstrap setup-webdriver.php tests 运行它

谷歌测试首先运行，运行良好，但当雅虎测试运行时，它会退出

1) YahooTest::testYahooTitle
curl_setopt() expects parameter 1 to be resource, integer given

我只是添加了对CCD_ 2的调用，试图找出错误的原因&这显然是因为curl资源已经从Google测试的有效资源变成了Yahoo测试时的0。

设置这个的原因是，我有一个完整的工作测试套件（用于一个工作项目），但目前它在一个脚本中运行大约50个测试，我正试图找出如何将测试划分为逻辑组/文件，同时共享同一个webdriver实例-在我看来，最好的方法是使用引导文件来设置webdriver&然后重用它。我展示的代码只是概念的证明，我很清楚在phpunit测试中调用print_r（）、echo等并不是正确的测试方法，我只是想学习&了解如何实现这一点。

首先，不要使用全局变量，使用PHPUnit中可用的fixture

class BaseTestCase extends PHPUnit_Framework_TestCase
{
    static $driver;
    public static function setUpBeforeClass()
    {
        $host = 'http://localhost:4444/wd/hub';
        $capabilities = DesiredCapabilities::firefox();
        self::$driver = RemoteWebDriver::create($host, $capabilities, 5000);
    }
    public static function tearDownAfterClass()
    {
        self::$driver->close();
    }
    public function getDriver()
    {
        return self::$driver;
    }
}
class GoogleTest extends BaseTestCase
{
    public function setUp()
    {
        $this->getDriver()->get('http://www.google.com/');
    }
    public function testTitle()
    {
        echo $this->getDriver()->getTitle();
    }
    public function testSomethingElse()
    {
        // do test
    }
}

class YahooTest extends BaseTestCase
{
    public function testYahooTitle()
    {
        $this->getDriver()->get('http://www.yahoo.com/');
        echo $this->getDriver()->getTitle();
    }
}

这个例子不会在GoogleTest和YahooTest之间共享相同的$driver，但这是推荐的，因为你希望每个测试都有一个干净的记录。

但是，GoogleTest中的所有测试都将共享相同的驱动程序。当您进行"phpunit测试"时，测试的执行顺序将是：

setUpBeforeClass() 
setUp()
testTitle()
setUp()
testSomethingElse()
tearDownAfterClass()
