linux - 在 linux box 上运行 nightwatch.js 测试？

Question

我正在尝试在安装了 Centos OS 的 linux 机器上运行 nightwatch 自动化 ui 测试。我在开始时遇到了问题。

这是我在 nightwatch.json 中的 test_settings 配置

"test_settings": {
        "default": {
            "launch_url": "",
            "selenium_port": 4444,
            "selenium_host": "localhost",
            "silent": true,
            "screenshots": {
                "enabled": true,
                "on_failure": true,
                "on_error": true,
                "path": "./screenshots"
            },
            "detailed_option": true,
            "end_session_on_fail": false,
            "desiredCapabilities": {
                "browserName": "chrome",
                "javascriptEnabled": true,
                "acceptSslCerts": true,
                "chromeOptions": {
                    "args": [
                        "use-fake-device-for-media-stream",
                        "use-fake-ui-for-media-stream"
                    ]
                }
            }
        },

我安装了 linux 64 位 chrome 驱动程序。然后我安装了 selenium 独立服务器。但是当我想要使用 node nightwatch 进行 nightwatch 测试时，我得到一个错误

“连接被拒绝!Selenium 未启动..”

如何设置 linux box 来运行 nightwatch 自动化 UI 测试？

当我将 start_process 设置为 false 并单独运行 selenium 服务器时，出现以下错误:

14:23:41.158 WARN - Exception: unknown error: Chrome failed to start: exited abnormally

您的 nightwatch.json 看起来缺少许多对象，特别是 selenium 服务器设置，这将解释 “连接被拒绝!Selenium 未启动..”。例如，这是我的，其中大部分将特定于您的环境:
