Tests for database migrations.
|
|
There are "opportunistic" tests 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 db's 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;
