Database access is costly in tests and many tests
don't actually need it. This patch provides a
simple way we can speed up the Nova tests by
providing a new base class, `NoDBTestCase` which
allows us to white-list tests not needing database
access.
The following speedups were observed:
With TestCase: Ran 265 tests in 17.080s
With NoDBTestCase: Ran 265 tests in 9.478s
Further optimizaton could be done by fixing
`test_host_filters` to not hit the database. This
will require some effort though in order to
maintain the quality of test coverage since part
of what's doing is testing the code in the DB
layer.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at:
Developers should also join the discussion on the mailing list, at:
Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests. Further developer focused documentation is available at:
