安装chrome driver

chrome driver建议通过科学上网的方式下载。

下载地址

下载完成后请将chromedriver.exe(windows)放到系统PATH中

验证chrome driver是否正确安装，请在命令行中输入

chromedriver -h
Usage: chromedriver [OPTIONS]

Options
  --port=PORT                     port to listen on
  --adb-port=PORT                 adb server port
  --log-path=FILE                 write server log to file instead of stderr, increases log level to INFO
  --verbose                       log verbosely
  --version                       print the version number and exit
  --silent                        log nothing
  --url-base                      base URL path prefix for commands, e.g. wd/url
  --port-server                   address of server to contact for reserving a port
  --whitelisted-ips               comma-separated whitelist of remote IPv4 addresses which are allowed to connect to ChromeDriver

如能看到上述结果则证明安装成功

简单的环境验证测试

新建文件start.js，并键入下面的内容。

// start.js
var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().forBrowser('chrome').build();

driver.get('http://itest.info');

console.log('quit driver');
driver.quit();

在命令行中运行
