selenium-chromedriver - Nightwatch - 使用 chromedriver

Question

所以我在 stack here 上看到了一个类似的问题，但它没有被接受的答案，也没有为我提供我需要的信息。

我正在尝试使用“chromedriver”，因为“selenium-webdriver”需要 FF 版本 <= 28。

到目前为止我所做的。

nightwatch.js 测试在 FF 中运行良好

将 chromedriver ( npm install chromedriver -g ) 和 npm install chromedriver 下载到我的 nightwatch 项目目录

去 nightwatch/bin/nightwatch.json 并编辑了以下代码

 "selenium" : {
"start_process" : false,
"server_path" : "",
"log_path" : "",
"host" : "127.0.0.1",
"port" : 4444,
"cli_args" : {
  "webdriver.chrome.driver" : "/usr/local/bin/chromedriver", <= added this - is this the binary?
  "webdriver.ie.driver" : "",
  "webdriver.firefox.profile" : ""
}},

还尝试更新 selenium 的设置，使其具有 start_process=true 和 server_path

 "selenium" : {
    "start_process" : true,
    "server_path" : "../selenium-server-standalone-2.39.0.jar",
    "log_path" : "",
    "host" : "127.0.0.1",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "/usr/local/bin/chromedriver",
      "webdriver.ie.driver" : "",
      "webdriver.firefox.profile" : ""
    }
  },

不确定我是否指向正确的 chromedriver 文件/文件夹

还编辑了测试设置

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_host" : "127.0.0.1",
      "selenium_port" : 4444,
      "silent" : true,
      "disable_colors": false,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "desiredCapabilities" : {
        "browserName" : "chrome",   <= changed this from ff to chrome
        "javascriptEnabled" : true,
        "acceptSslCerts" : true
      }
    },

如果我去运行测试(没有 -e <browser> )例如nightwatch -g <group> ，它在 FF 中启动良好并运行..

如果我尝试指定 chrome 浏览器 ( -e chrome ) nightwatch -g <group> -e chrome 我会收到以下错误

ERROR There was an error while starting the test runner:


Error: Invalid testing environment specified: chrome

    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)

我的问题是:

我如何指向二进制文件(不确定它是哪个)

我在 nightwatch.js 中的设置是否正确？如果我更改了 test_settings 'browserName = Chrome"，它如何在 FF 中运行？

我在这里遗漏了什么吗？

提前致谢

Answer 1

首先你说

I am trying to use 'chromedriver' because 'selenium-webdriver' requires a FF version <= 28.

因为你用的是 selenium-server-standalone-2.39.0.jar (旧 jar) 请从这里下载新的 selenium-server-standalone-2.45.0.jar
第二次从这里下载 chrome 驱动程序 Chromedriver基于您的环境
第三次使用以下代码更新您的 nightwatch.json

{
"src_folders": [
    "tests"
],
"selenium": {
    "start_process": false,
    "server_path": "bin/selenium-server-standalone-2.45.0.jar",
    "log_path": "",
    "host": "127.0.0.1",
    "port": 4444,
    "cli_args": {
        "webdriver.chrome.driver": "bin/chromedriver",
        "webdriver.ie.driver": ""
    }
},
"test_settings": {
    "default": {
        "launch_url": "http://127.0.0.1/",
        "selenium_port": 4444,
        "selenium_host": "localhost",
        "silent": true,
        "screenshots": {
            "enabled": false,
            "path": ""
        },
        "desiredCapabilities": {
            "browserName": "firefox",
            "javascriptEnabled": true,
            "acceptSslCerts": true
        }
    },
    "chrome": {
        "desiredCapabilities": {
            "browserName": "chrome",
            "javascriptEnabled": true,
            "acceptSslCerts": true
        }
    }
}

}
第四次使用 nightwatch -g -e chrome 运行你的小组
希望它能解决你的问题。
