xvfbwrapper 0.2.7

Basic Usage:

from xvfbwrapper import Xvfb

vdisplay = Xvfb()
vdisplay.start()

# launch stuff inside
# virtual display here.

vdisplay.stop()

Basic Usage, specifying display geometry and color depth:

from xvfbwrapper import Xvfb

vdisplay = Xvfb(width=1280, height=740, colordepth=16)
vdisplay.start()

# launch stuff inside
# virtual display here.

vdisplay.stop()

Usage as a Context Manager:

from xvfbwrapper import Xvfb

with Xvfb() as xvfb:
    # launch stuff inside virtual display here.
    # It starts/stops around this code block.

Testing Example: Headless Selenium WebDriver Tests:

import unittest

from selenium import webdriver
from xvfbwrapper import Xvfb


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 above code uses selenium and xvfbwrapper to run a test with Firefox inside a headless display.

It will:

• install selenium bindings: pip install selenium

• Firefox will launch inside virtual display (headless)

• browser is not shown while tests are run

Look Ma’, no browser!
