javascript - 拒绝连接! Selenium 服务器是否已启动

Question

我继承了一个没有文档的工作项目。这是一个sails.js 应用程序。有一小部分单元测试和一个端到端测试。

当我尝试使用 grunt 运行端到端测试时。我明白了:

$ grunt e2e
Running "nightwatch" task
started - PID:  5440
>> Executing "default" tests (standalone)

[Index] Test Suite
==================

Running:  Should clean the collection

removing 0 places
>> Connection refused! Is selenium server started?

我不知道我会错过什么。这让我卡了一个多星期。

该项目在 grunt-nightwatch 中有一个 selenium-server-standalone-2.40.0.jar。所以我取的PID是selenium server启动的。如果我先启动 jar (在咕噜声之外)，我会得到

$ grunt e2e
org.openqa.grid.selenium.GridLauncher main
INFO: Launching a standalone server
18:38:46.189 WARN - Failed to start: SocketListener0@0.0.0.0:4444
Exception in thread "main" java.net.BindException: Selenium is already running on port 4444. Or     some other service is.
    at org.openqa.selenium.server.SeleniumServer.start(SeleniumServer.java:491)
    at org.openqa.selenium.server.SeleniumServer.boot(SeleniumServer.java:300)
    at org.openqa.selenium.server.SeleniumServer.main(SeleniumServer.java:245)
    at org.openqa.grid.selenium.GridLauncher.main(GridLauncher.java:95)
>> Could not start Selenium.

这是 nightwatch.json

{
  "src_folders" : ["tests/e2e"],
  "custom_commands_path" : "",
  "custom_assertions_path" : "",
  "globals_path" : "",

  "selenium" : {
    "start_process" : false,
    "server_path" : "",
    "log_path" : "",
    "host" : "127.0.0.1",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "",
      "webdriver.ie.driver" : ""
    }  
  },

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_port"  : 4444,
      "selenium_host"  : "localhost",
      "silent": true,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },

    "chrome" : {
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    }
  }
}

非常感谢您的帮助!

 "webdriver.chrome.driver" : "",

您需要在 nightwatch.json 文件的这一行中指定您的 chrome 驱动程序位置

例如，我使用:

"webdriver.chrome.driver" : "~/bin/chromedriver",

您是否也开始使用 selenium 以使用 chrome 驱动程序？如果在您启动 selenium 时没有，请附加:-Dwebdriver.chrome.driver=/Users/[用户名]/bin/chromedriver

所以当你启动 selenium 服务器时，它应该看起来像终端 cmd:java -jar [SeleniumServerName] -Dwebdriver.chrome.driver=/Users/[用户名]/bin/chromedriver

记得先将CD放入seleniumserver文件夹，然后根据Windows更改文件/文件夹路径结构。
