Python XVFB error in windows

Question

For virtual Framebuffer (headless testing) I'm using Xvfb with PyVirtualDisplay and it's working fine in Ubuntu but showing error in Windows7. here is part of code where problem is occurring.

from pyvirtualdisplay import Display
display = Display(visible=1, size=(300, 400))
display.start() 

but when I run same command in Windows, I get this error

Traceback (most recent call last):
  File "C:\Python27\Scripts\pynt-script.py", line 9, in <module>
    load_entry_point('pynt==0.8.0', 'console_scripts', 'pynt')()

    build(sys.argv[1:])

ck_installed
    raise EasyProcessCheckInstalledError(self)
easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Error 2] The system cannot find the file specified
Program install error! 

I think my program is not able to find xvfb program/library ? I installed xvfbwrapper (https://github.com/cgoldberg/xvfbwrapper) but problem still remain same. again I think xvfbwrapper is different from xvfb?

Any alternative for Windows platform which can do headless testing (virtual framebuffer)

Answer 1

You get an error because command Xvfb was not found. Xvfb is X virtual framebuffer which is not a part of Microsoft Windows 7.
