}

nightwatch.conf.js

  module.exports = {
  "src_folders" : ["./src/nightWatch"],"webdriver" : {
      "start_process": true,"server_path": "node_modules/chromedriver/lib/chromedriver/chromedriver","port": 9515
  },"test_settings" : {
      "default" : {
          "desiredCapabilities": {
              "browserName": "chrome"
          }
      }
  }
}

当我运行脚本 npm run browsertest 时，我直接收到了 google chrome 拒绝的连接。我已经在浏览器中停用了沙箱并禁用了所有代理。我也改变了端口，但我就是想不通。

有没有人有解决办法？我有 Debian 10 作为操作系统

error

解决方法

您好，我找到了解决方案。我有几个实例在运行，因此 npm start 然后选择了一个与我在测试中定义的端口不同的端口。已杀死端口上的所有进程并重新启动
