Comment 8 for bug 1251657

so from

python_test() {
        # https://bugs.launchpad.net/nova/+bug/1235955
        local DISTUTILS_NO_PARALLEL_BUILD=1
        mv $(find . -name test_ovs_tunnel.py) ./troubled || die

        testr init
        testr run --parallel || die "failed testsuite under python2.7"
}

we have

Ran 18665 tests in 1689.939s
FAILED (id=0, failures=2, skips=328)
 * ERROR: sys-cluster/neutron-2013.2-r1::gentoo failed (test phase):
 * failed testsuite under python2.7

as always with NO traceback, setting a rather nouvelle mystery.

from http://paste.openstack.org/show/53681/ from .testrepository/0
we have

pythonlogging:''

ok python logging gets turned on

2013-11-20 22:49:57,995 INFO [neutron.manager] Loading Plugin: neutron.plugins.bigswitch.plugin.NeutronRestProxyV2

the traceback begins at neutron.plugins.bigswitch.plugin,
who knows what the instigating test was. Here's a hint;

successful: neutron.tests.unit.bigswitch.test_restproxy_plugin.TestBigSwitchProxyNetworksV2.

just occurred before, so it appears it's likely from neutron.tests.unit.bigswitch.test_restproxy_plugin.py

2013-11-20 22:49:58,108 ERROR [neutron.api.extensions] Extension path 'unit/extensions' doesn't exist!

Oh dear, that's problematic.

$ find ...../neutron-2013.2/ -name extensions
  .....neutron-2013.2/neutron/tests/unit/extensions

perhaps?

should it not be seeking Extension path 'neutron/tests/unit/extensions' ??????????

no less than 36 times. That's problematic. Now note;

Is this 78 mb of log that backtraces to neutron system packages, never reaches the actual instigating tests and lists 2 FAILS despite listing _emulate_bulk_create on 36 separate occasions. In the filed of analysing testsuites, this one really breaks new ground.
The good news is 2 out of 18665 tests in 1689.939s is not so bad
The bad news is for all the 78 mb of logging we have no idea WHAT THE TESTS ARE, in addition to this test still having an invalid invalid status
