This is hardcoded to use django-discover-runner since that's my main test runner but could easily be adopted to use Django's own test runner. If you're using a terminal that is capable of showing 256 colors use the Terminal256Formatter formatter instead.

Enabled it with the TEST_RUNNER setting:

TEST_RUNNER = 'dotted.path.to.highlighted.runner.HighlightedDiscoverRunner'

Where dotted.path.to.highlighted.runner is the Python import path of the file you saved the runner in.

This would be really useful to have in the standard Django testrunner! :-)

This is now the standard test runner!

as django-discover-runner now comes with django (since 1.6), you should replace 

from discover_runner import DiscoverRunner

by

from django.test.runner import DiscoverRunner
