Docker Selenium/Standalone Chrome无法连接到Docker Web服务器

我正在尝试使用codeception为使用Docker容器开发的PHP网站运行测试。 我在Web容器中创建了一个测试文件夹,并将codecept.phar放在那里。

这是项目的设置:

• docker-compose.yml:

  version: '3'
    services:
      db:
        image: mariadb
        restart: always
        volumes:
          - ./db:/var/lib/mysql
        ports:
          - '3306:3306'
        environment:
          MYSQL_ROOT_PASSWORD: root
      web:
        build: .
        restart: always
        tty: true
        volumes:
          - ./src:/var/www
          - ./build/php.ini:/usr/local/etc/php/php.ini
        ports:
          - '80:80'
        depends_on:
          - db
      chrome:
        image: selenium/standalone-chrome
        restart: always
        ports:
          - '4444:4444'
          - '5900:5900'
        depends_on:
          - web
  

• 验收.suite.yml

  actor: AcceptanceTester
  modules:
    enabled:
      - WebDriver:
          url: web
          host: chrome
          browser: chrome
          wait: 15
          window_size: false
      - \Helper\Acceptance
  

我用以下方式开始容器:

docker-compose up

然后我将shell附加到Web容器,并使用以下命令运行测试:

php codecept.phar build && php codecept.phar run --steps

我正在运行一个简单的测试,它基本上尝试检查元素是否存在并截图: -测试1.php:

$I = new AcceptanceTester($scenario);
$I->amOnUrl('http://127.0.0.1');
$I->makeScreenshot();
$I->waitForElement(".modal");

但是测试没有正常运行,因为Chrome容器无法连接到Web容器。屏幕截图显示的页面显示:

This site can't be reached
127.0.0.1 refused to connect

这是运行codeception的附加shell中显示的错误:

[Facebook\WebDriver\Exception\NoSuchElementException] no such element: Unable to locate element: {"method":"css selector","selector":".modal"}
(Session info: chrome=68.0.3440.84)
(Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 4.9.0-7-amd64 x86_64)

虽然我可以连接到 http://127.0.0.1:4444/wd/hub

这是我从运行“docker compose up”的shell得到的输出:

我认为,为Docker撰写容器建立网络应该可以解决这个问题。 我试着按照码头工人的文件( Network configuration reference )将网络设置为“主机”,但似乎已过时,因为版本3中不允许使用名称。

还尝试设置从chrome到web的链接,运行chrome而不使用compose(docker run--net=host selenium/standalone chrome),但没有改变。

你知道怎么做吗? 谢谢你的帮助!
