I am using python 2.7.3 and bin/py interpreter prompt to run :

>>> master = TestableMaster()
>>> master.start()

But the following error occurs :
--------------------------------------------------------------------------
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sandesh/mail_man/mailman-3.0.0b2/src/mailman/testing/helpers.py",
line 186, in start
    self.start_runners(runners)
  File "/home/sandesh/mail_man/mailman-3.0.0b2/src/mailman/bin/master.py",
line 385, in start_runners
    for runner_config in config.runner_configs:
  File "/home/sandesh/mail_man/mailman-3.0.0b2/src/mailman/config/config.py",
line 215, in runner_configs
    for section in self._config.getByCategory('runner', []):
AttributeError: 'NoneType' object has no attribute 'getByCategory'
