Python wrapper for running a display inside X virtual framebuffer (Xvfb)
Corey Goldberg - 2012, 2013
Install xvfbwrapper from PyPI
pip install xvfbwrapper
System Requirements
Xvfb (sudo apt-get install xvfb, or similar)
Python 2.7 or 3.2+ (tested on py27, py32, py33, pypy)
About Xvfb (X Virtual Framebuffer)
In the X Window System, Xvfb or X virtual framebuffer is an X11 server that performs all graphical operations in memory, not showing any screen output. This virtual server does not require the computer it is running on to even have a screen or any input device. Only a network layer is necessary.
Example: Basic Usage
from xvfbwrapper import Xvfb vdisplay = Xvfb() vdisplay.start() # launch stuff inside virtual display here vdisplay.stop()
Example: Headless Selenium WebDriver Tests
from selenium import webdriver
from xvfbwrapper import Xvfb
import unittest
class TestPages(unittest.TestCase):
def setUp(self):
self.xvfb = Xvfb(width=1280, height=720)
self.addCleanup(self.xvfb.stop)
self.xvfb.start()
self.browser = webdriver.Firefox()
self.addCleanup(self.browser.quit)
def testUbuntuHomepage(self):
self.browser.get('http://www.ubuntu.com')
self.assertIn('Ubuntu', self.browser.title)
def testGoogleHomepage(self):
self.browser.get('http://www.google.com')
self.assertIn('Google', self.browser.title)
if __name__ == '__main__':
unittest.main(verbosity=2)
This code uses selenium and xvfbwrapper to run a test with Firefox inside a headless display.
install selenium bindings: pip install selenium
Firefox will launch inside virtual display (headless)
browser is not shown while tests are run
