How to test custom django-admin commands
If you're using some coverage tool it would be good to call it from the code with:
from django.core.management import call_commandfrom django.test import TestCaseclass CommandsTestCase(TestCase): def test_mycommand(self): " Test my custom command." args = [] opts = {} call_command('mycommand', *args, **opts) # Some Asserts.From the official documentation
Management commands can be tested with the call_command() function. The output can be redirected into a StringIO instance
You should make your actual command script the minimum possible, so that it just calls a function elsewhere. The function can then be tested via unit tests or doctests as normal.
you can see in github.com examplesee here
def test_command_style(self): out = StringIO() management.call_command('dance', style='Jive', stdout=out) self.assertEquals(out.getvalue(), "I don't feel like dancing Jive.")
