[Selenium][1] is an umbrella project for a range of tools and libraries that enable
and support the automation of web browsers.

```
$ docker-compose up -d
```
> Another way to start selenium server:

$ selenium-standalone start
```

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(
command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities=DesiredCapabilities.FIREFOX
)
driver.get('http://www.baidu.com/')
driver.find_element_by_id('kw').send_keys('webdriver')
driver.find_element_by_id('su').click()
driver.save_screenshot('baidu.png')
driver.close()
```
search-baidu.js
```
var webdriver = require('selenium-webdriver'),
By = require('selenium-webdriver').By,
until = require('selenium-webdriver').until,
fs = require('fs');
webdriver.WebDriver.prototype.saveScreenshot = function(filename) {
return driver.takeScreenshot().then(function(data) {
fs.writeFile(filename, data.replace(/^data:image\/png;base64,/,''), 'base64', function(err) {
if(err) throw err;
});
})
};
var driver = new webdriver.Builder()
.forBrowser('firefox')
.usingServer('http://127.0.0.1:4444/wd/hub')
.build();
driver.get('http://www.baidu.com/');
driver.findElement(By.id('kw')).sendKeys('webdriver');
