The --keepdb flag is not respected for test databases

[boc-tdunn]

The django docs state that the --keepdb flag should keep the test database from being destroyed after a test run, and that subsequent test runs should not recreate the test database if it exists already.

https://docs.djangoproject.com/en/5.1/topics/testing/overview/#the-test-database

For reference the POSTGRES django adapter does this.

Somewhat related issue is that Django allows you to provide the name of the test database:
https://docs.djangoproject.com/en/5.1/ref/settings/#std-setting-DATABASE-TEST

But python-ibmdb-django always uses this format instead:
https://github.com/ibmdb/python-ibmdb-django/blob/master/ibm_db_django/creation.py#L169

For reference this is what BaseDatabaseCreation does in django:
https://github.com/django/django/blob/main/django/db/backends/base/creation.py#L185-L186

If you'd rather this be a separate issue let me know and I'll do that instead.

@boc-tdunn usually customers wont keep test database hence we ignored this option. We will handle this in coming releases.

I can't promise anything but would this be an issue you would accept a contribution for?

[praveen-db2]

I didnt understand.

[boc-tdunn]

Would I be allowed to submit a Pull Request for this issue?

[praveen-db2]

yes sure, we appreciate everybody's contribution. But we merge it when we plan for next release.
