Best way to disable settings from appengine_config during tests

[Andi Albrecht]

Hi all,

I have set up local unit tests for a Python app according to the
documentation on the App Engine site [1]. The app has appstats
configured as a WSGI middleware through appengine_config.py by using
the webapp_add_wsgi_middleware() directive:

def webapp_add_wsgi_middleware(app):
app = recording.appstats_wsgi_middleware(app)
return app

When running the tests I want to disable appstats. appstats needs
REQUEST_ID_HASH environment variable which isn't set during tests, but
recording data doesn't make much sense at all during tests.

The current idea is to monkey-patch
appengine_config.webapp_add_wsgi_middleware when it's first imported
by the test runner - before any test is actually executed:

import appengine_config
appengine_config.webapp_add_wsgi_middleware = lambda app: app

But I wonder if there are better (or more documented) alternatives to
modify settings from appengine_config.py during tests.

You can try:

def webapp_add_wsgi_middleware(app):

  if not appos.environ['APPLICATION_ID'].startswith('dev~'):

    app = recording.appstats_wsgi_middleware(app)

  return app

That's an interesting idea. I'd just do it the other way round and add appstats only iff APPLICATION_ID doesn't starts with 'test-' since I'm already setting this prefix when setting up the test environment.

Thanks!
