|
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;
