There is an exception if api_extensions is set to empty in tempest.conf

[Simeon Monov]

If api_extensions is set to empty in tempest.conf (like api_extensions=) there is an exception in test.is_extension_enabled code.

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/nose/suite.py", line 208, in run
    self.setUp()
  File "/usr/lib/python2.7/dist-packages/nose/suite.py", line 291, in setUp

  File "/home/moni/src/openstack1/tempest/tempest/test.py", line 218, in is_extension_enabled
    if config_dict[service][0] == 'all':
IndexError: list index out of range

This is valid for all the sections in the file that has this parameter: compute-feature-enabled, network-feature-enabled, volume-feature-enabled.

This could be set to empty to disable the tests of all the extensions for a particular service for example. Workaround is to set it to non existent extension:

[network-feature-enabled]
api_extensions = none

    Fix exception when api_extensions is set to empty

    test.is_extension_enabled() is not checking if
    config_dict[service] list is empty

    Added a check if config_dict[service] is empty the
    function will return False which means no extensions
    are enabled
