Unit test to check for ungenerated migrations

Question

Has anyone written a unit test to verify if there are ungenerated migrations in their Django app? I think it should probably look something like:

1. Call python manage.py makemigrations
2. scrape results into a parsable object
3. verify "no migrations were found"
4. if migrations are found list them, fail the test, and delete the generated files

If not, I am going to write one so that we fail our build.

Since Django 1.10 the makemigrations management command has included a --check option. The command will exit with a non-zero status if migrations are missing.

Usage example:

./manage.py makemigrations --check --dry-run
