Tests for database migrations. There are "opportunistic" tests here, supported
|
|
backends are: sqlite (used in test environment by default), mysql and
|
|
postgresql, which are required properly configured unit test environment.
|
|
|
|
For the opportunistic testing you need to set up a db named 'openstack_citest'
|
|
with user 'openstack_citest' and password 'openstack_citest' on localhost.
|
|
The test will then use that db and u/p combo to run the tests.
