Flaky withConn Tests in internal_test.go

[Parvezkhan0]

I observed that the withConn tests in internal_test.go often fail due to connection errors. Interestingly, they tend to pass in the CI environment.

Details:

The tests are designed to establish a connection to Redis at 127.0.0.1:6379, but the test setup does not initiate a Redis server. In the CI pipeline, these tests succeed because another Redis instance is running for a different test case.

Additionally, it's worth noting that these withConn tests are located within the Redis package, rather than in redis_test, where the BeforeSuite function initializes Redis.

Hello @Parvezkhan0, thank you for reporting this. We are working on improving the test setup, but it will be done in couple of iterations. If you have any other suggestions on how to do this, please share.
