在 Firefox 中使用 Nightwatch 运行测试无法连接到 Selenium 服务器

Question

我正在尝试使用 Nightwatch.js 对网站进行自动化测试，并且我使用的是 macOS High Sierra。 因此，我开始使用文档中所述的 Selenium Standalone Server 进行测试。 chrome 测试效果很好，我对此没有任何问题。但我似乎无法让 Firefox 测试工作，我一直在测试和在线搜索修复但我放弃了，因为我发现没有一个解决方案有效。 这是我的 nightwatch.json 配置文件。

{
    "src_folders": [
        "test"
    ],
    "output_folder": "reports",
    "custom_commands_path": "",
    "custom_assertions_path": "",
    "page_objects_path": "",
    "globals_path": "",
    "selenium": {
        "start_process": true,
        "server_path": "./bin/selenium-server-standalone-3.13.0.jar",
        "log_path": "",
        "port": 4444,
        "cli_args": {
            "webdriver.chrome.driver": "./bin/chromedriver",
            "webdriver.gecko.driver": "./bin/geckodriver",
            "webdriver.firefox.profile": "nightwatch"
        }
    },
    "test_settings": {
        "default": {
            "launch_url": "https://www.google.com",
            "selenium_port": 4444,
            "selenium_host": "127.0.0.1",
            "default_path_prefix": "",
            "silent": true,
            "screenshots": {
                "enabled": false,
                "path": ""
            },
            "desiredCapabilities": {
                "browserName": "firefox",
                "javascriptEnabled": true,
                "acceptSslCerts": true,
                "marionette": true
            }
        },
        "chrome": {
            "desiredCapabilities": {
                "browserName": "chrome",
                "chromeOptions": {
                    "args": [
                        "--load-extension=/Users/jackch/Downloads/chrome, --url-base=/wd/hub"
                    ]
                }
            }
        }
    }
}

然后当我在终端中运行nightwatch -e --verbose 时，我得到了同样的错误Error retrieving a new session from the selenium server Connection refused! Is selenium server started?。 我尝试了很多东西：

1) 我在默认端口 4444 上的单独终端中启动了 geckodriver，以下是 geckodriver 的日志：

2018-07-23 12:09:03.432 plugin-container[27769:6329668] *** CFMessagePort: bootstrap_register(): failed 1100 (0x44c) 'Permission denied', port = 0x7903, name = 'com.apple.tsm.portname'

See /usr/include/servers/bootstrap_defs.h for the error codes.

2）然后我尝试更改geckodriver的端口，因为我认为它们可能会干扰，因为Selenium和gecko都选择了4444端口，但没有任何改变。

3) 我尝试单独启动 Selenium 服务器，然后链接它。这意味着我在 nightwatch.json 中将 "start_process" 设置为 false。而且我还是没能成功。

这是我运行nightwatch -e --verbose后的完整消息：

    Starting selenium server... started - PID:  28112
