[Question] Async Client and testing with RedisContainer

[bearrito]

Hello,

I'm attempting to use the RedisContainer inside a IsolatedAsyncioTestCase
It seems like the below works

from redis.asyncio import Redis
from testcontainers.redis import RedisContainer


class AsyncRedisContainer(RedisContainer):
    """
    Redis container.

    Example
    -------
    .. doctest::

        >>> from testcontainers.redis import AsyncRedisContainer

        >>> with AsyncRedisContainer() as redis_container:
        ...     redis_client =await  redis_container.get_async_client()
    """

    def __init__(
        self, image="redis:latest", port_to_expose=6379, password=None, **kwargs
    ):
        super(AsyncRedisContainer, self).__init__(
            image, port_to_expose, password, **kwargs
        )

    async def get_async_client(self, **kwargs):
        return await Redis(
            host=self.get_container_host_ip(),
            port=self.get_exposed_port(self.port_to_expose),
            password=self.password,
            **kwargs,
        )

class TestAyncRedisContainerContainer(IsolatedAsyncioTestCase):
    async def test_foo(self):
        with AsyncRedisContainer.AsyncRedisContainer() as container:
            async_redis_client: redis.Redis = await container.get_async_client(
                decode_responses=True
            )
            key = "key"
            expected_value = 1
            await async_redis_client.set(key, expected_value)
            actual_value = await async_redis_client.get(key)
            self.assertEqual(int(actual_value), expected_value)

Is there a cleaner way to do this? If so, would there be any interest in a PR?

For grooming purposes re: #405

Would you like a PR for this? If not I can close.

heyo! thanks for coming back! :)
It's a worthwhile idea to properly support async for all containers in fact!
With my current level of energy, I'm not sure I can squeeze it in right now.

If you want you can contribute just this one, but then the last ask is to make use of AnyIO for testing
https://anyio.readthedocs.io/en/stable/testing.html

Reason for that:

• it integrates with pytest, following the pytest fixtures
• it is better than pytest-asyncio because of the support for the higher scope fixtures (the default is function level)

Okay. That shouldnt be an issue. I had this in a work project and these were our standard libs, but I can split it out and make use of the libs you suggested.

Closing. Opened a PR.
