设置Nightwatch.js Conf文件

Question

我是夜莺的新手，我正试着运行这个命令

$ nightwatch --env gecko /test1/test1 1/sample1.js

我试图弄清楚如何通过命令行从nightwatch.json文件中选择浏览器。

这是我的文件。我正在阅读关于Nightwatch.js的教程，似乎找不到这个设置。

{
"src_folders": [
    "tests"
],
"selenium": {
    "start_process": false,
    "server_path": "bin/selenium-server-standalone-2.53.1.jar",
    "log_path": "",
    "host": "127.0.0.1",
    "port": 4444,
    "cli_args": {
        "webdriver.chrome.driver": "bin/chromedriver",
        "webdriver.gecko.driver" : "bin/geckodriver"
    }
},
"test_settings": {
    "default": {
        "launch_url": "http://127.0.0.1/",
        "selenium_port": 4444,
        "selenium_host": "localhost",
        "silent": true,
        "screenshots": {
            "enabled": false,
            "path": ""
        },
        "desiredCapabilities": {
            "browserName": "chrome",
            "javascriptEnabled": true,
            "acceptSslCerts": true
        }
    }
    "gecko": {
    "launch_url": "http://127.0.0.1/",
    "selenium_port": 4444,
    "selenium_host": "localhost",
    "silent": true,
    "screenshots": {
        "enabled": false,
        "path": ""
    },
    "desiredCapabilities": {
        "browserName": "gecko",
        "javascriptEnabled": true,
        "acceptSslCerts": true
        }
    }
}
}

我得到的错误信息是

Error: No testing environment specified.

Answer 1

不确定是不是这样，但您至少在这里需要一个逗号：

},
    "gecko"

Answer 2

可以尝试使用以下代码：

  {
  "src_folders": [
    "tests"
  ],
  "output_folder": "reports",
  "custom_commands_path": "",
  "custom_assertions_path": "",
  "page_objects_path": "pages",
  "globals_path": "",
  "selenium": {
    "start_process": false,
    "server_path": "bin/selenium-server-standalone-2.53.1.jar",
    "start_session": true,
    "log_path": "",
    "host": "127.0.0.1",
    "port": 4444,
    "cli_args": {
      "webdriver.chrome.driver": "bin/chromedriver",
      "webdriver.gecko.driver" : "bin/geckodriver"
    }
  },
  "test_settings": {
    "default": {
      "launch_url" : "http://localhost",
      "selenium_port": 4444,
      "selenium_host": "localhost",
      "silent": true,
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },
    "gecko": {
      "desiredCapabilities": {
        "browserName": "firefox",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    }
  }
}
