Message::new(\"test_topic\", b\"test_data\");\n    broker.send_message(message).await.unwrap();\n\n    let received = broker.consume_message(\"test_topic\", 0).await.unwrap();\n    assert_eq!(received.data(), b\"test_data\");\n}\n```\n\n3. **Performance Testing**\n\n```rust\n#[bench]\nfn bench_message_throughput(b: \u0026mut Bencher) {\n    let broker = setup_test_broker();\n\n    b.iter(|| {\n        for i in 0..1000 {\n            let message = Message::new(\"bench_topic\", format!(\"message_{}\", i).as_bytes());\n            broker.send_message(message).unwrap();\n        }\n    });\n}\n```\n\n#### Debugging \u0026 Profiling\n\n1. **Enable Debug Logging**\n\n```bash\nRUST_LOG=debug cargo run\n```\n\n2. **Performance Profiling**\n\n```bash\n# CPU profiling\ncargo run
