Redis Cache With Django Rest Framework Testing

Question

In my current project I have some code that requires caching (I use Redis for now).And for that reason I can't use fake cache or mock. And through the tests I need a clean cache, so at setup of test case class I use the following:

from django_redis import get_redis_connection
get_redis_connection("default").flushall()

Which breaks the parallel testing(and can make race condition). What's the best practice of testing with active caching?

Answer 1

For anyone who passes by, I've changed the cache backend to LocMemCache when testing. After that, caches aren't affected by parallel testing anymore.

Something like this:

TESTING = 'test' in sys.argv
if TESTING:
    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        }
    }
else:
    CACHES = {
        'default': {
            'BACKEND': 'django_redis.cache.RedisCache',
            'LOCATION': REDIS_HOST,
        }
    }

Caution: some operations which are supported by RedisCache, aren't supported by LocMemCache. cache.ttl() is an example.
