run_test.py w/ new directory

Hi,

I have created a new subdiretory ~/nova/nova/attestation with a new file service.py. I have also create a new unit test under ~/nova/tests/scheduler/test_attestation.py where has "from nova.attestation import service"

When I run "python run_tests.py scheduler.test_attestation:TestAttestation.test_sdk", I am experiencing following error.
that can't locate attestation directory. Do I need to specify new created directory in anyplace for testing?

Thanks,

fred@storky:~/d2/nova$ python run_tests.py scheduler.test_attestation:TestAttestation.test_sdk
