I'm solving this with a custom test runner. Here is an example I based my solution off of: https://github.com/xintron/django-mongorunner/blob/master/mongorunner/testrunner.py

This has the advantage of providing a fresh database for each of your unit tests.

class MyTestRunner(DjangoTestSuiteRunner):

    mongodb_name = 'testsuite'

    def setup_databases(self, **kwargs):
        from mongoengine.connection import connect, disconnect
        disconnect()
        connect(self.mongodb_name)
        print 'Creating mongo test-database ' + self.mongodb_name
        return super(MyTestRunner, self).setup_databases(**kwargs)

    def teardown_databases(self, old_config, **kwargs):
        from mongoengine.connection import get_connection, disconnect
        connection = get_connection()
        connection.drop_database(self.mongodb_name)
        print 'Dropping mongo test-database: ' + self.mongodb_name
        disconnect()
        super(MyTestRunner, self).teardown_databases(old_config, **kwargs)
