Question

These are the two apps in my INSTALLED_APPS list which is giving me a problem.

1. django.contrib.messages
2. sentry.client

One unit test in particular is doing an assertRaises expecting a django.contrib.messages.api.MessageFailure.

sentry.client installs a signal handler that listens for got-request-exception.
During the test execution, the signal handler attempts to log the exception to sentry & this cause sentry.client to fail with a HTTP Error 400: BAD REQUEST. The sentry code says that it will avoid the logging if the exception type possesses an attribute “.

Where can I monkeypatch django.contrib.messages.api.MessageFailure like so:

MessageFailure.skip_sentry = True

Obviously I don’t want to change the django test sources.

I haven’t used sentry before, but to add a skip_entry attribute to the MessageFailure class you use a mix-in. Add the following code in a module that’s guaranteed to run when your Django server starts up [any models.py should work]:

from django.contrib.messages.api import MessageFailure
class MessageFailureMixin:
    skip_sentry = True
MessageFailure.__bases__ += (MessageFailureMixin,)
