"""Usage:
sniffer -x --js-app_manager -x corehq.apps.app_manager:AppManagerViewTest

You can get sniffer to run both js and python tests. Set which js tests you want to run with `--js-{app_name}`
Use the nose syntax for python tests
When you save a .js file, the js tests run,
When you save a .py file, the python tests run.
