无法通过jenkins在ec2亚马逊Linux实例上运行测试用例。

Question

当我在ec2实例上通过jenkins运行测试用例时，得到了错误信息。

下面是我的nightwatch配置。

{
    "src_folders" : ["test"],
    "globals_path": "globals.js",
    "output_folder" : "reports",
    "custom_commands_path" : "./commands",
    "custom_assertions_path" : "./assertions",

    "test_workers" : {
        "enabled" : false, 
        "workers" : "auto"
      },


"selenium" : {
  "start_process" : true,
  "server_path" : "./bin/selenium-server-standalone-4.0.0.jar",
  "log_path" : "",
  "port" : 4444,
  "cli_args" : {
    "webdriver.chrome.driver" : "./bin/chromedriver_linux"
  }
},

    },

    "skip_testcases_on_fail" : false,
    "use_xpath" : true,
    "globals" : {

    }, 
    "desiredCapabilities": {
      "browserName": "chrome",
      "chromeOptions": {
        "w3c": false,
        "args" : ["headless","no-sandbox"]
      },
      "javascriptEnabled": true,
      "acceptSslCerts": true
    }
  }
}

}

在控制台得到以下错误信息。

我已经在ec2实例中安装了chrome浏览器(81.0.4044.129)和它们各自的chrome linux驱动。

硒服务器 selenium-server-standalon-4.0.0.jar。

注意：我在我的本地机器(MAC OS)上配置了Jenkins，工作正常。我在本地机器(MAC OS)上配置了Jenkins，工作正常。

我相信你的EC2服务器上的安全组没有ICMP IPV4入站规则，无法访问你的服务器，运行这个守夜人脚本。请尝试在你提供的ec2服务器的ICMP IPV4入站规则中添加你的nightwatch服务器的IP地址，或者你甚至可以将其公开。我希望这能解决你的问题。
