Tests for database migrations. This test case reads the configuration
file test_migrations.conf for database connection settings
to use in the tests. For each connection found in the config file,
the test case runs a series of test cases to ensure that migrations work
properly both upgrading and downgrading, and that no data loss occurs
if possible.
There are also "opportunistic" tests for both mysql and postgresql in here,
which allows testing against all 3 databases (sqlite in memory, mysql, pg) in
a 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.
For postgres on Ubuntu this can be done with the following commands:
sudo -u postgres psql
postgres=# create user openstack_citest with createdb login password
'openstack_citest';
postgres=# create database openstack_citest with owner openstack_citest;
