Subclass of DjangoTestSuiteRunner, to run every test cases from a module with Django. I think this is more pythonic than Django's.

module_test_suite_runner.py

import django.test.simple as dj_test
from django.test.simple import unittest

class ModuleTestSuiteRunner(dj_test.DjangoTestSuiteRunner):
    def build_suite(self, test_labels, extra_tests=None, **kwargs):
        suite = unittest.TestSuite()

        if test_labels:
            for label in test_labels:
                if '.' in label:
                    #suite.addTest(build_test(label))
                    try:
                        suite.addTest(dj_test.build_test(label))
                    except ValueError:
                        head, tail = label.split('.', 1)
                        full_label = '.'.join([head, dj_test.TEST_MODULE, tail])
                        tests = unittest.defaultTestLoader.loadTestsFromName(full_label)
                        suite.addTests(tests)

                else:
                    app = dj_test.get_app(label)
                    suite.addTest(dj_test.build_suite(app))


        else:
            for app in dj_test.get_apps():
                suite.addTest(dj_test.build_suite(app))

        if extra_tests:
            for test in extra_tests:
                suite.addTest(test)

        return dj_test.reorder_suite(suite, (dj_test.TestCase,))
