我正在尝试使用Nightwatch.js对网站进行自动测试，而我正在使用macOS High Sierra . 所以我开始使用文档中所述的Selenium Standalone Server进行测试 . Chrome测试工作正常，我没有问题 . 但我似乎无法使Firefox测试工作，我一直在测试和在线搜索修复，但我放弃了，因为我找不到任何解决方案 . 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，我得到了相同的错误 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上的一个单独的终端中启动了geckodriver，这里是来自geckodriver的日志：

2)然后我试图改变 geckodriver 的端口，因为我认为他们可能会因为Selenium和gecko都选择了4444端口，但没有任何改变 .

3)我试图单独启动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 . 我仍然无法使其发挥作用 .

这是我运行 nightwatch -e --verbose 后的完整消息：
