How can I take a screenshot with Selenium WebDriver?

Question

Is it possible to take a screenshot using Selenium WebDriver?

(Note: Not Selenium Remote Control)

Answer 1

Python

Each WebDriver has a .save_screenshot(filename) method. So for Firefox, it can be used like this:

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')

Confusingly, a .get_screenshot_as_file(filename) method also exists that does the same thing.

There are also methods for: .get_screenshot_as_base64() (for embedding in HTML) and .get_screenshot_as_png()(for retrieving binary data).

And note that WebElements have a .screenshot() method that works similarly, but only captures the selected element.
