FakeAsyncRedis stores state when clear instance expected.

[irusland]

Describe the bug
When creating FakeAsyncRedis each time we get same instance of redis.

To Reproduce

import asyncio

import fakeredis


async def main():
    redis_client_1 = fakeredis.FakeAsyncRedis()
    await redis_client_1.set('k', 'v')

    redis_client_2 = fakeredis.FakeAsyncRedis()
    v2 = await redis_client_2.get('k')

    assert v2 is None, f'Value of new redis is {v2}'


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

produces
AssertionError: Value of new redis is b'v'

Expected behavior
Code runs successfully same as

import fakeredis


def main():
    redis_client_1 = fakeredis.FakeRedis()
    redis_client_1.set('k', 'v')

    redis_client_2 = fakeredis.FakeRedis()
    v2 = redis_client_2.get('k')

    assert v2 is None, f'Value of new redis is {v2}'


if __name__ == '__main__':
    main()

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: macOS Ventura 13.4.1
• python version: 3.10.12
• redis-py version: aioredis==2.0.1, redis==5.0.1
• full requirements.txt: aioredis==2.0.1, fakeredis==2.21.0, redis==5.0.1

Additional context
Not sure if it's an intended behaviour. But anyways I expect same behaviour as FakeRedis

It is the intended behavior.

You can supply different connection parameters to get different fake servers.

Thanks for quick response!

Could you please provide me an example? Or point out the necessary code in documentation?

Solved it with using different each time port=...

import asyncio

import fakeredis


async def main():
    redis_client_1 = fakeredis.FakeAsyncRedis(port=1)
    await redis_client_1.set('k', 'v')

    redis_client_2 = fakeredis.FakeAsyncRedis(port=2)
    v2 = await redis_client_2.get('k')

    assert v2 is None, f'Value of new redis is {v2}'


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Yeah, that works.
It behaves the same as redis.Redis - by default the connection parameters are localhost:6389.
