About xvfbwrapper:
----------------------
xvfbwrapper is a python wrapper for controlling Xvfb.
----
---------------
About Xvfb:
---------------
Xvfb (X virtual framebuffer) is a display server implementing the X11 display server protocol. It runs in memory and does not require a physical display. Only a network layer is necessary.
Xvfb is especially useful for running acceptance tests on headless servers.
----
----------------------------------
Install xvfbwrapper from PyPI:
----------------------------------
``pip install xvfbwrapper``
----
------------------------
System Requirements:
------------------------
* Xvfb (``sudo apt-get install xvfb``, or similar)
* Python 2.7 or 3.3+
----
++++++++++++
Examples
++++++++++++
****************
Basic Usage:
****************
::
from xvfbwrapper import Xvfb
vdisplay = Xvfb()
vdisplay.start()
# launch stuff inside
# virtual display here.
vdisplay.stop()
----
*********************************************
Basic Usage, specifying display geometry:
*********************************************
::
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()
The test class above uses `selenium` and `xvfbwrapper` to run each test case with Firefox inside a headless display.
* virtual display is launched
* Firefox launches inside virtual display (headless)
* browser is not shown while tests are run
* conditions are asserted in each test case
* browser quits during cleanup
* virtual display stops during cleanup
*Look Ma', no browser!*
(You can also take screenshots inside the virtual display for diagnosing test failures)
