I'm a freshman in openstack. I want to contribute and learn some exciting by joining openstack. I will be grateful if anyone can help me on my starting process.

Now I encounter a problem when I tried the UT with tox.
I execute the following command,

(.venv-nova)[jiapei2 at localhost nova]$ tox -e py27 tests.unit.api.openstack.compute.test_server_action

And then I got the results:
Ran: 136 tests in 51.0000 sec.
- Passed: 40
- Skipped: 0
- Expected Fail: 0
- Unexpected Success: 0
- Failed: 96
Sum of execute time for each test: 293.4456 sec.

One of the errors is like,

Is there anyting wrong with my configurations or procedures? I didn't change any code and just run "tox".
Any advice will be much appreciated.

Thanks and regards,
