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

## Server
|
|
|

$ docker-compose up -d
|
|
$ curl http://127.0.0.1:4444/
|
|
```
|
|
|
|
> Another way to start selenium server:
|
|
|
|
```bash
|
|
$ npm install -g selenium-standalone
|
|
$ selenium-standalone install
|
|
$ selenium-standalone start
|

|
|
|
capabilities = DesiredCapabilities.CHROME
|
|
proxy.add_to_capabilities(capabilities)
|
|
|
|
driver = webdriver.Remote(

|
)
|
|
|
|
driver.get('http://www.baidu.com/')
|
|

|
|
driver.find_element_by_id('su').click()
|
|
|
|
WebDriverWait(driver, 10).until(
|
|
EC.presence_of_element_located((By.CLASS_NAME, 'nums_text'))
|
|
)
|
|
|
|
driver.save_screenshot('baidu.png')
|
|
driver.close()
|
|
```

|
```javascript
|

|
|
|
|
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')
