#25357 closed Bug (fixed)

setup_databases doesn't deduplicate databases correctly on Oracle

Description

The short version is that, when setup_databases detects that two databases are identical, it does connection.settings_dict['NAME'] = ... instead of calling connection.creation.set_as_test_mirror().

I'm going to attach a project that allows reproducing the issue. (Unfortunately, we don't have a convenient way to test the test runner's database creation features.)

If you set DATABASES = DATABASES_POSTGRES in the settings, the test passes.

If you set DATABASES = DATABASES_ORACLE in the settings, the test fails with myapp.models.DoesNotExist: MyModel matching query does not exist..

Fixed #25357 -- Database deduplication on Oracle.

In order to reuse another database, Django must use set_as_test_mirror.
