Make it possible to run individual tests.
## Code Before:
import os
import sys

import django
from django.conf import settings
from django.test.utils import get_runner

if __name__ == "__main__":
    os.environ['DJANGO_SETTINGS_MODULE'] = 'tests.test_settings'
    django.setup()
    TestRunner = get_runner(settings)
    test_runner = TestRunner()
    failures = test_runner.run_tests(["tests"])
    sys.exit(bool(failures))

## Instruction:
Make it possible to run individual tests.
## Code After:
import os
import sys

import django
from django.conf import settings
from django.test.utils import get_runner

if __name__ == "__main__":
    tests = "tests" if len(sys.argv) == 1 else sys.argv[1]
    os.environ['DJANGO_SETTINGS_MODULE'] = 'tests.test_settings'
    django.setup()
    TestRunner = get_runner(settings)
    test_runner = TestRunner()
    failures = test_runner.run_tests([tests])
    sys.exit(bool(failures))
