我一直在尝试使用 Behat 3.1、Selenium 3.6 和 Mink 创建一些测试，但没有成功……我不知道如何解决这个问题：如果我触发了php bin/behat我的 Firefox 启动的命令，但我的网站没有加载. 几分钟后我得到一个错误：

场景：访问登录页面
给定我在'/login'
无法打开连接：java.lang.reflect.InvocationTargetException

构建信息：版本：'3.6.0'，修订：'6fbf3ec767'，时间：'2017-09-27T16 :15:40.131Z'

系统信息: 主机: 'xxx.xxx.xxx.xxx', ip: 'xxx.xxx.xxx.xxx', os.name: 'Mac OS X', os.arch: 'x86_64' , os.version: '10.13', java.version: '1.8.0_72'

Driver info: driver.version: unknown (Behat\Mink\Exception\DriverException)

当我按下 'Startseite'
然后我应该看到 'einloggen'

我的行为.yml

# behat.yml

我的 FeatureContext.php

use Behat\Behat\Context\Context;
use Behat\MinkExtension\Context\MinkContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;

    }

    public function iAmOn($arg1)
    {
        $this->visit($arg1);
    }

    /**

    public function iPress($arg1)
    {
        $this->getSession()

            ->findButton($arg1)
            ->press();
    }

    /**

    public function iShouldSee($arg1)
    {
        $this->assertPageContainsText($arg1);
    }
}

我的登录功能

Feature: login page
    In order to see login contens
    As a user
    I am able to visit login page

    @javascript @login
    Scenario: visit login page
        Given I am on '/login'
        When  I press 'Startseite'
        Then  I should see 'einloggen'

我的 GuiContext

    use Behat\Behat\Context\BehatContext;
    use Behat\Gherkin\Node\PyStringNode;

    use Behat\Mink\Mink,
        Behat\Mink\Session,
        Behat\Mink\Driver\Selenium2Driver,
        Behat\MinkExtension\Context\MinkContext;

    use Nearsoft\SeleniumClient as SeleniumClient;

    require_once 'PHPUnit/Autoload.php';
    require_once 'PHPUnit/Framework/Assert/Functions.php';

    class GuiContext extends MinkContext
    {

        public function __construct(array $parameters)
        {
            $mink = new Mink(array(
                'selenium2' => new Session(new Selenium2Driver($parameters['wd_capabilities']['browser'], $parameters['wd_capabilities'], $parameters['wd_host'])),
            ));
            $this->gui = $mink->getSession('selenium2');
        }

        /**
         * @When /^wait (\d+) seconds?$/
         */
        public function waitSeconds($seconds)
        {
            $this->getSession()->wait(1000*$seconds);
        }
    }

我已经阅读了很多论坛，老实说我现在很困惑......

我感谢任何形式的帮助！

最好的问候伊曼纽尔

我们已经将 Behat 与 Firefox 一起使用了很长时间，并且我们经常遇到您所描述的问题。有时我们甚至将 Firefox 版本降级以能够运行 Behat 功能。

我们切换到chromedriver，从那时起我们就再也没有遇到过任何问题（如果您在 Mac 上，请使用 安装它brew install chromedriver）。这是我们对 Behat 的配置：

default:
  gherkin:
    filters:
      tags: @mytag
  autoload:
    '': %paths.base%/bootstrap
  extensions:
    Behat\MinkExtension:
      base_url: https://site.local
      goutte:
        guzzle_parameters:
          verify: false
      browser_name: 'chrome'
      selenium2:
        capabilities: { "browserName": "chrome", "browser": "chrome", 'chrome': {'switches':['--no-sandbox']}}

  suites:
    mysuite:
      paths:    [ %paths.base%/features ]
      contexts:
        - FeatureContext
        - GuiContext

如果您仍然想使用 Firefox 来运行 Behat with Selenium，请确保您拥有最新版本的 Selenium Standalone Server http://docs.seleniumhq.org/download/。

此外，考虑使用安装了 Selenium 和浏览器的 Docker 映像https://hub.docker.com/u/selenium/，它已经过预配置并经过测试可以正常工作。

更新 1

使用没有构造函数的 GuiContext 并扩展 RawMinkContext：

class GuiContext extends RawMinkContext
{
    /**
     * @When /^wait (\d+) seconds?$/
     */
    public function waitSeconds($seconds)
    {
        $this->getSession()->wait(1000*$seconds);
    }
}

在功能中指定@javascript标签后，Behat 将自动切换到 selenium 驱动程序。

更新 2：

要启动 selenium，请执行以下命令：

java -jar selenium-server-standalone-3.6.0.jar >& /tmp/selenium.log &

假设 3.6.0 是从链接下载的 selenium 的最新版本。您还可以使用 composer 要求 selenium 服务器：

composer require se/selenium-server-standalone

然后启动它：

/your-project/vendor/bin/selenium-server-standalone
