The django-nose test suite as of v1.4, April 2015, did not include database testing. This means that features such as REUSE_DB=1 will continue to break, and only be discovered when used against other projects.

Since v1.4.1, the following has been added:

• Test settings to use environment variables, to unify the various test cases into one config.
• Database settings to use dj-database-url, so that tests can run against different backends
• Add models and model tests to testapp, so that database operations are exercised
• Add test runs for REUSE_DB=1 and similar options, to replicate failures.

Now we have the infrastructure to fix database issues and detect problems with future Django versions.
