Disabled module falsely claims that it is sending messages during tests

[martey]

Django 1.8.2, Opbeat 2.1.1

I have disabled Opbeat by setting OPBEAT["APP_ID"] = None. When I run ./manage.py test, I get the following lines printed out at the end of each run:

PID 19301: Opbeat is attempting to send 1 pending messages
Waiting up to 10 seconds, press Ctrl-C to quit
PID 19301: done, took 0.12 seconds to complete

Based on what I can tell with netstat, Opbeat correctly realizes that it is disabled and does not really attempts to send messages to the intake servers. The messages are still sort of confusing, though.

Thanks for the report! This is indeed a problem. In this case, the pending message is from the APM middleware, not an exception. We are looking into introducing a cleaner way to disable Opbeat collecting any data (see #36).

As a workaround, you can try removing the APM middleware during tests:

MIDDLEWARE_CLASSES.remove('opbeat.contrib.django.middleware.OpbeatAPMMiddleware')

MIDDLEWARE_CLASSES is a tuple, so the suggested workaround gave me an error. Removing the APM middleware did work with the following code:

MIDDLEWARE_CLASSES = tuple(
    middleware for middleware in MIDDLEWARE_CLASSES
    if middleware != "opbeat.contrib.django.middleware.OpbeatAPMMiddleware")

I belive this issue is present again with Django 1.11:
