Comment:

 It's [https://docs.djangoproject.com/en/3.0/ref/databases/#oracle-notes
 documented] that to run a project's test suite in on Oracle the user needs
 additional privileges, e.g. ''"CREATE TABLESPACE"''.

 > the actual destruction of tables depends on this line if
 `self._test_database_create()`:

 Not really, all tables are created in a test user scope, so they should be
 dropped when we drop test user.

 > However, the `CREATE_DB` governs the ability to create the database, not
 the tables within.

 It's about creating/dropping test tablespaces, see
 [https://docs.djangoproject.com/en/3.0/ref/settings/#create-db
 documentation]. Django doesn't manage pluggable databases.

 > As for most Oracle devs, there is no way I will be allowed to get DB-
 create permissions of tablespace create permissions.

 It's a matter of your company policy, I worked 10 years with Oracle DBs
 and it has never been an issue.

 To sum up if you don't have permissions to create/drop tablespaces, then
 you need at least permissions to create/drop a test user. In such case
 settings like

 {{{
 'TEST': {
     'USER': 'JB_UNITTEST',
     'PASSWORD': 'y',
     'CREATE_DB': False,
     'CREATE_USER': True,
 }
 }}}
 should work properly.
