Check backend setup about cashews

[Krukov]

Hi.

While I try to find answer for your question I found that there is no clear way to check setup of cache.
Here some option to do it and in future I will add more simpler way
First option that may help is also a PING method, it should fail if you use unsafe mode with cache :

import asyncio
from cashews import cache

cache.setup("redis://", safe=False)
print(asyncio.run(cache.ping(b"test")))

Even with safe mode you can check a returning of a ping method , it should be the same as you pass to it ( but do not use PONG - it is a bug)

import asyncio

from cashews import cache

cache.setup("redis://")
print(asyncio.run(cache.ping(b"message")) == b"message")

# False
