[Answered ]-How to run Django context processor

You can print some value just like this:

def some_context_processor(request):
    return {'system_name': 'test'}

and in your html:

{{ system_name }}

The django debug toolbar is useful for this. Its template panel shows you all the templates rendered, and the values returned by all the context processors.

For debugging in python in general, just add import pdb to the top of the script which you wish to debug and use pdb.set_trace() in whichever line you wish to insert a breakpoint.

Run the server and as the control reaches the line containing pdb.set_trace() take a look at your development server prompt, you can access all local vars to check what vars hold what value.
