fab test generates error on Windows

[Abdelkrim]

running fab test on windows generates the following error, could you help me understand how to correct the issue.

It seems that the test isn't meant to be executed on Windows?

$ fab test
[localhost] local: theme=default python testrunner.py /usr/local/google_appengine ./
'theme' is not recognized as an internal or external command,
operable program or batch file.

Fatal error: local() encountered an error (return code 1) while executing 'theme=default python testrunner.py /usr/local
/google_appengine ./'

Aborting.
