If your test uses Redis, please execute the following Docker Compose command before running the program, and ensure that the required port 6379 is not already in use to avoid any conflicts.

version: "3.8"
services:
  redis:
    image: redis:latest
    ports:
      - "6379:6379"

$ docker-compose up -d
