Module¶oslo_db.sqlalchemy.test_base.
DbFixture
(test, skip_on_unavailable_db=True)¶Bases: fixtures.fixture.Fixture
Basic database fixture.
Allows to run tests on various db backends, such as SQLite, MySQL and PostgreSQL. By default use sqlite backend. To override default backend uri set env variable OS_TEST_DBAPI_ADMIN_CONNECTION with database admin credentials for specific backend.
DBNAME
= 'openstack_citest'¶DRIVER
= 'sqlite'¶PASSWORD
= 'openstack_citest'¶USERNAME
= 'openstack_citest'¶setUp
()¶Prepare the Fixture for use.
This should not be overridden. Concrete fixtures should implement _setUp. Overriding of setUp is still supported, just not recommended.
After setUp has completed, the fixture will have one or more attributes which can be used (these depend totally on the concrete subclass).
MultipleExceptions if _setUp fails. The last exception captured within the MultipleExceptions will be a SetupError exception.
None.
The recommendation to override setUp has been reversed - before 1.3, setUp() should be overridden, now it should not be.
BaseException is now caught, and only subclasses of Exception are wrapped in MultipleExceptions.

DbTestCase
(*args, **kwds)¶Bases: oslotest.base.BaseTestCase
Base class for testing of DB code.
SCHEMA_SCOPE
= None¶SKIP_ON_UNAVAILABLE_DB
= True¶generate_schema
(engine)¶Generate schema objects to be used within a test.
The function is separate from the setUp() case as the scope of this method is controlled by the provisioning system. A test that specifies SCHEMA_SCOPE may not call this method for each test, as the schema may be maintained from a previous run.

¶setUp
()¶Hook method for setting up the test fixture before exercising it.
