Django compatibility

@pkrefta No problem. You can set the verbosity by adding a Green config file (see the bottom of the help; the section starts with CONFIG FILES.

Ah, my first run-in with Django. Until now, it has only been a word I have seen tossed around in distant forums and conference talks. :-) Thanks for providing the minimal project and example command to start with, that helps a bunch.

This looks like a good place for research to start

I'll check this out and see how hard this looks to do after I finish issues #14 and #7 that I'm deep into.

If anyone wants to check it out further in the meantime, please do!

Ok, I got curious so I went and looked at things. It looks like the apparently standard Django manage.py script just hooks into a command-line processing library inside of Django (decent design, there).

The ./manage.py test subcommand has a --testrunner=TESTRUNNER option that expects some type of testrunner class. Apparently there are Django-specific expectations for the test runner, as neither green.runner.GreenTestRunner nor unittest.runner.TextTestRunner will work when passed in. I bet this is going to be the best integration point with Django.

I need to find Django's expectations (hopefully nicely documented) for the test runner class they want to use. Assuming the expectations are not too crazy, I could write a green.runner.Django class that conforms to those expectations.

It may be wise for me to implement #20 before implementing this functionality, otherwise there would be no way to configure green when you're running it through Django.

I envision an implementation where the user would end up doing this to run their Django tests through Green:

./manage.py test --testrunner=green.runner.Django

So I think I know where to go for this one, but I want to resolve some of these other issues before I hit this one. (Pull requests welcome in the meantime!)

If there is some other (better) integration point with Django, someone please speak up and let me know!

#20 has been implemented. No more blockers that I know of.

Okay, I have been working on this all morning and I'm afraid I am a bit stumped.

Django won't let you import the test stuff without already being configured in the context of a project. That makes it really, really annoying to develop and test something you want to subclass.

Not stumped anymore! If the django settings env variable is not present, I use stubbed out config settings. I've got a prototype working already. :)

@CleanCut Thanks for django. I don't want to open another to ask simple question - how can I set verbosity for DjangoRunner ? 😄
