No module name tests

[SONAL ...]

Hey i have directory structure as
gkwebapp/gnukhata-webapp/gnukhata/tests/functional in which we have our test
files.

When i run tests, get following error:

Traceback (most recent call last):
  File "test_account.py", line 1, in <module>
    from gnukhata.tests import *
ImportError: No module named gnukhata.tests

Why do this error come?? I have searched a lot but no use. Can you please
