It doesn't look like the Alembic migrations have ever been tested properly with SQLite... or anything for that matter.
I do not understand how the base storage SQLAlchemy test case is doing a conn.upgrade() in its setUp() method and tests are actually passing... none of it seems to work when you try it out.
Also, things to keep in mind... Alembic does not handle a number of SQLite ALTER TABLE missing operations, namely DROP COLUMN and RENAME COLUMN:

We worked around this with SQLite specialized migration SQL scripts in sqlalchemy-migrate, but the same does not exist in Alembic. Instead it looks like we will need to jump through a number of hoops -- including copying table schemas and data into new table schemas.
