TestInsertQueue.test_insert_queue_header_asterisk failed with 204 != 201

More details: http://paste.openstack.org/show/72691/

In my local development environment, I'm running into this failure. But obviously, it's weird why it's not reported by Jenkins.

I'm wondering if there are something wrong with the created check, see
https://github.com/openstack/marconi/blob/master/marconi/queues/transport/wsgi/v1_0/queues.py#L43

[Feilong Wang (flwang)]

It would be appreciated if anybody can verify this with your own env.

[Feilong Wang (flwang)]

Just verified, this works with a running Marconi server. Not sure if it's caused by cached sqlite database. Will dig into it.

I can't recreate this now with the latest code(master branch).

[prashanth raghu (p-isprashanth)]

Observed in master.

Steps to reproduce this bug:
--------------------------------------

1. After running marconi-server, run the unit tests using tox -e py27.
2. Now you will notice that all the tests pass successfully.
3. From your REST client issue a GET request using http://127.0.0.1:8888/queues .
4. You will observe that there is a queue named : "asteriskinheader".
5. Now run the tests again executing : tox -e py27.

You can observe that because of the already existing queue a 204 response is observed.
The response can be traced back to the code queues.py in line number 51 where HTTP_204 is added to the response for already existing queues.

    Improve cleanup of test_insert_queue_header_asterisk

    Based on current implement, the queue created by
    test_insert_queue_header_asterisk won't be deleted.
    As a result, develper will run into unit test failure
    like 204!=201. This fix will add the headers param to
    make sure the queue can be cleaned up.
