Selenium WebDriverJS,无法为Chrome构建webdriver

Question

我在设置Selenium WebDriverJS时遇到了一些麻烦.我的目标是使用Javascript(节点)在Chrome浏览器上运行selenium测试.

我按照https://code.google.com/p/selenium/wiki/WebDriverJs上的说明以及https://code.google.com/p/chromedriver/wiki/GettingStarted

首先我下载了​​chromedriver,然后在终端上运行:

$ ./chromedriver
Starting ChromeDriver (v2.2) on port 9515

然后,我安装了selenium-webdriver:

$ npm install selenium-webdriver
npm http GET https://registry.npmjs.org/selenium-webdriver
npm http 304 https://registry.npmjs.org/selenium-webdriver
selenium-webdriver@2.35.0 node_modules/selenium-webdriver

然后,我启动了节点控制台并尝试构建webdriver实例

$ node
> var webdriver = require('selenium-webdriver')
undefined
> var driver = new webdriver.Builder().usingServer('http://localhost:9515/wd/hub').withCapabilities(webdriver.Capabilities.chrome()).build();
undefined
> 
timers.js:103
            if (!process.listeners('uncaughtException').length) throw e;
                                                                      ^
UnknownCommandError: unknown command: wd/hub/session
    at new bot.Error (/selenium/node_modules/selenium-webdriver/lib/atoms/error.js:109:18)
    at Object.bot.response.checkResponse (/selenium/node_modules/selenium-webdriver/lib/atoms/response.js:103:11)

    at notifyAll (/selenium/node_modules/selenium-webdriver/lib/webdriver/promise.js:297:7)
    at fulfill (/selenium/

现在我被封锁了.有人可以帮帮我吗？我在这里错过了什么？

谢谢

这里有几件事.

1. 默认情况下,chromedriver服务器处理/,而不是/ wd/hub的命令.所以你应该能够做到:

   new webdriver.Builder().usingServer('http://localhost:9515').build();
   

2. 如果您希望chromedriver具有与独立Selenium服务器相同的签名,请启动它--url-base=/wd/hub.

3. 没有必要自己启动chromedriver - 如果您请求Chrome并省略服务器位置(确保可以在您的系统上找到chromedriver),selenium-webdriver将为您执行此操作PATH:

   new webdriver.Builder()
       .withCapabilities(webdriver.Capabilities.chrome())
       .build();
