nightwatchjs并行模式selenium hub docker撰写

标签: javascript selenium selenium-webdriver nightwatch.js

我正在尝试使用Selenium Hub在Docker中使用nightwatchjs并行编写测试。我能够在没有Selenium Hub的情况下在Docker中并行运行测试,但是,一些子进程将超时导致多次重试。结果非常不一致。我希望使用Selenium Hub或类似的东西来删除超时和重试,以便测试结果更加一致,稳定,不会超时。

但是,现在当我运行docker-compose run --rm nightwatch时,使用以下代码,selenium服务器将以并行模式启动,并且将启动多个子进程,但是,只会执行第一个子进程。然后其他子进程将获得Error retrieving a new session from the selenium server. Connection refused! Is selenium server started?我是否遗漏了一些内容以使nightwatchjs测试并行运行而没有超时?

nightwatch.conf.js

    port: 4444,
    cli_args: {
      'webdriver.chrome.driver' : './node_modules/chromedriver/bin/chromedriver'
    }
  },

  test_settings: {
    default: {
    launch_url: 'https://example.com',
    selenium_port: 4444,
    selenium_host: 'hub',
    silent: true,

      'path': ''
    },
    desiredCapabilities: {

          '--window-size=1024,768',
          '--no-sandbox'
        ]
      }
    },
    globals: {
      waitForConditionTimeout: 20000,
      asyncHookTimeout: 70000

docker节点映像配置为仅运行一个浏览器实例。您可以通过覆盖环境变量来更改此设置,如下所示:

  chrome:
    environment:
      VIRTUAL_HOST: node.chrome.docker
      HUB_PORT_4444_TCP_ADDR: hub
      HUB_PORT_4444_TCP_PORT: 4444
      NODE_MAX_INSTANCES: 5
      NODE_MAX_SESSION: 5
    image: selenium/node-chrome:3.1.0-astatine
    links:
      - hub

如果您有兴趣,我会通过查看Dockerfile source来发现这一点。
