Install

pip install django-fakeredis

Why use it?

I have experienced many times to find bugs which is caused by mutiple fakeredis instances in tests. We just want to use fakerredis like redis with one redis-server and different connections.

Pros:

• One fakeredis server with mutiple connections for tests like the way of using redis.
• Combine override settings to DummyCACHE and fake get_redis_connection
• To disable the fake action with passing env: "NOFAKE_REDIS=1" NOFAKE_REDIS=1 python manage.py test

Before you use django_fakeredis, your everty test code maybe like that:

server = fakeredis.FakeServer()
@override_settings(CACHES={"default": {"BACKEND": "django.core.cache.backends.dummy.DummyCache" }})
@patch('foo.get_redis_connection', fakeredis.FakeRedis(server=server)
def test_sth():
    ....

Now your can just:

@FakeRedis("yourpath.get_redis_connection")
def test_sth():
    ...

Usage

from django_fakeredis import FakeRedis
@FakeRedis("yourpath.get_redis_connection")
def test_foo():
    ...

from django_fakeredis import FakeRedis
with FakeRedis("yourpath.get_redis_connection"):
    foo()

from django_fakeredis import FakeRedis
with FakeRedis("yourpath.cache"):
    foo()

NOTE

If you want to mock django.core.cache.cache with fakeredis, you should notice that there are internal cast in django cache. i.e:

from django.core.cache import cache
cache.set("key", 2)
assert cache.get("key") == 2

but if you use fakeredis, you have to cast by hand:

con.set("key", 2)
concache.get("key").decode('utf8') == "2"

So I suggest to use django_redis with fakeredis in django.
