《星球大战》和《人体掠夺者》：在LinuxBox上运行夜视测试

我正在尝试在linux机箱（centos）上运行nightwatch自动UI测试。我有以下nightwatch.json配置：

                        "use-fake-ui-for-media-stream"
                    ]
                }
            }
        },
      "jenkins" : {
            "selenium_port"  : 4444,

            "chromeOptions" : {
                "args" : ["--no-sandbox"]
            } 
            }
    }
}   

我正在使用詹金斯环境

我已将chromedriver安装到lib/文件夹 我将selenium-standalone.jar安装到lib/文件夹

但是当我通过node nightwatch运行测试时——test tests/login.js

我得到一个错误：

Error retrieving a new session from the selenium server


Connection refused! Is selenium server started?

我做错了什么？

很可能是您的服务器路径。我在安装Nightwatch之前遇到过这个问题，最后搜索node_模块中的子目录以找到selenium服务器独立jar。有时我甚至不得不单独安装它。目前我把它命名为“服务器路径”：“/node\u modules/testarmada magellan nightwatch/node\u modules/selenium server/lib/runner/selenium-server-standalone-2.52.0.jar”，尽管你很可能在别处找到它。它很可能是你的服务器路径。我在安装Nightwatch之前遇到过这个问题，最后搜索node_模块中的子目录以找到selenium服务器独立jar。有时我甚至不得不单独安装它。目前我将其命名为“服务器路径”：“/node_modules/testarmada magellan nightwatch/node_modules/selenium server/lib/runner/selenium-server-standalone-2.52.0.jar”，尽管您很可能在其他地方找到它。
