This is my big issue.  dropping / creating databases for unit tests is
overkill.  Running any DDL at all for a unit test seems wrong to me
too.  Insert a row if you need it, MAYBE.  Unit tests should work with
a test database that HAS the structure and database already in place.

What happens if your unit tests get lose in production and drop a
database, or a table.  Not good.
