+
+```bash
+# Cluster endpoints
+SEAWEED_MASTERS="master0:9333,master1:9334,master2:9335"
+SEAWEED_BROKERS="broker1:17777,broker2:17778,broker3:17779"
+SEAWEED_FILERS="filer1:8888,filer2:8889"
+
+# Test configuration
+GO_TEST_TIMEOUT="30m"
+TEST_RESULTS_DIR="/test-results"
+```
+
+### Docker Compose Override
+
+Create `docker-compose.override.yml` to customize the test environment:
+
+```yaml
+version: '3.9'
+services:
+  broker1:
+    environment:
+      - CUSTOM_ENV_VAR=value
+  test-runner:
+    volumes:
+      - ./custom-config:/config
+```
+
+## Monitoring and Metrics
+
+### Prometheus Metrics
+
+Access Prometheus at: http://localhost:19090
+
+Key metrics to monitor:
+- Message throughput: `seaweedmq_messages_published_total`
+- Consumer lag: `seaweedmq_consumer_lag_seconds`
+- Broker health: `seaweedmq_broker_health`
+- Resource usage: `seaweedfs_disk_usage_bytes`
+
+### Grafana Dashboards
+
+Access Grafana at: http://localhost:13000 (admin/admin)
+
+Pre-configured dashboards:
+- **SeaweedMQ Overview**: System health and throughput
+- **Performance Metrics**: Latency and resource usage
+- **Error Analysis**: Error rates and failure patterns
+
+## Development
+
+### Writing New Tests
+
+1. **Create Test File**:
+   ```bash
+   touch integration/my_new_test.go
+   ```
+
+2. **Use Test Framework**:
+   ```go
+   func TestMyFeature(t *testing.T) {
+       suite := NewIntegrationTestSuite(t)
+       require.NoError(t, suite.Setup())
+       
+       // Your test logic here
+   }
+   ```
+
+3. **Run Specific Test**:
+   ```bash
+   go test -v ./integration/ -run TestMyFeature
+   ```
+
+### Test Framework Components
+
+**IntegrationTestSuite**: Base test framework with cluster management
+**MessageCollector**: Utility for collecting and verifying received messages
+**TestMessage**: Standard message structure for testing
+**Schema Builders**: Helpers for creating test schemas
+
+### Local Development
+
+Run tests against a local SeaweedMQ cluster:
+
+```bash
+make test-dev
+```
+
+This uses local binaries instead of Docker containers.
+
+## Continuous Integration
+
+### GitHub Actions Example
+
+```yaml
+name: Integration Tests
+on: [push, pull_request]
+
+jobs:
+  integration-tests:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - uses: actions/setup-go@v3
+        with:
+          go-version: 1.21
+      - name: Run Integration Tests
+        run: |
+          cd test/mq
+          make test
+```
+
+### Jenkins Pipeline
+
+```groovy
+pipeline {
+    agent any
+    stages {
+        stage('Setup') {
+            steps {
+                sh 'cd test/mq && make up'
+            }
+        }
+        stage('Test') {
+            steps {
+                sh 'cd test/mq && make test'
+            }
+            post {
+                always {
+                    sh 'cd test/mq && make down'
+                }
+            }
+        }
+    }
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Port Conflicts**:
+   ```bash
+   # Check port usage
+   netstat -tulpn | grep :19333
+   
+   # Kill conflicting processes
+   sudo kill -9 $(lsof -t -i:19333)
+   ```
+
+2. **Docker Resource Issues**:
+   ```bash
+   # Increase Docker memory (8GB+)
+   # Clean up Docker resources
+   docker system prune -a
+   ```
+
+3. **Test Timeouts**:
+   ```bash
+   # Increase timeout
+   GO_TEST_TIMEOUT=60m make test
+   ```
+
+### Debug Mode
+
+Run tests with verbose logging:
+
+```bash
+docker-compose -f docker-compose.test.yml run --rm test-runner \
+  sh -c "go test -v -race ./test/mq/integration/... -args -test.v"
+```
+
+### Container Logs
+
+View real-time logs:
+
+```bash
+make logs
+
+# Or specific service
+docker-compose -f docker-compose.test.yml logs -f broker1
+```
+
+## Performance Benchmarks
+
+### Throughput Benchmarks
+
+```bash
+make benchmark
+```
+
+Expected performance (on 8-core, 16GB RAM):
+- **Publish Throughput**: 50K+ messages/second/broker
+- **Subscribe Throughput**: 100K+ messages/second/broker
+- **End-to-End Latency**: P95 < 100ms
+- **Storage Efficiency**: < 20% overhead
+
+### Load Testing
+
+```bash
+make load-test
+```
+
+Stress tests with:
+- 1M+ messages
+- 100+ concurrent producers
+- 50+ concurrent consumers
+- Multiple topic scenarios
+
+## Contributing
+
+### Test Guidelines
+
+1. **Test Isolation**: Each test should be independent
+2. **Resource Cleanup**: Always clean up resources in test teardown
+3. **Timeouts**: Set appropriate timeouts for operations
+4. **Error Handling**: Test both success and failure scenarios
+5. **Documentation**: Document test purpose and expected behavior
+
+### Code Style
+
+- Follow Go testing conventions
+- Use testify for assertions
+- Include setup/teardown in test functions
+- Use descriptive test names
+
+## Future Enhancements
+
+- [ ] Chaos engineering tests (network partitions, node failures)
+- [ ] Multi-datacenter deployment testing
+- [ ] Schema evolution compatibility tests
+- [ ] Security and authentication tests
+- [ ] Performance regression detection
+- [ ] Automated load pattern generation
+
+## Support

+# SeaweedMQ Integration Test Design
+
+## Overview
+
+This document outlines the comprehensive integration test strategy for SeaweedMQ, covering all critical functionalities from basic pub/sub operations to advanced features like auto-scaling, failover, and performance testing.
+
+## Architecture Under Test
+
+SeaweedMQ consists of:
+- **Masters**: Cluster coordination and metadata management
+- **Volume Servers**: Storage layer for persistent messages
+- **Filers**: File system interface for metadata storage
+- **Brokers**: Message processing and routing (stateless)
+- **Agents**: Client interface for pub/sub operations
+- **Schema System**: Protobuf-based message schema management
+
+## Test Categories
+
+### 1. Basic Functionality Tests
+
+#### 1.1 Basic Pub/Sub Operations
+- **Test**: `TestBasicPublishSubscribe`
+  - Publish messages to a topic
+  - Subscribe and receive messages
+  - Verify message content and ordering
+  - Test with different data types (string, int, bytes, records)
+
+- **Test**: `TestMultipleConsumers`
+  - Multiple subscribers on same topic
+  - Verify message distribution
+  - Test consumer group functionality
+
+- **Test**: `TestMessageOrdering`
+  - Publish messages in sequence
+  - Verify FIFO ordering within partitions
+  - Test with different partition keys
+
+#### 1.2 Schema Management
+- **Test**: `TestSchemaValidation`
+  - Publish with valid schemas
+  - Reject invalid schema messages
+  - Test schema evolution scenarios
+
+- **Test**: `TestRecordTypes`
+  - Nested record structures
+  - List types and complex schemas
+  - Schema-to-Parquet conversion
+
+### 2. Partitioning and Scaling Tests
+
+#### 2.1 Partition Management
+- **Test**: `TestPartitionDistribution`
+  - Messages distributed across partitions based on keys
+  - Verify partition assignment logic
+  - Test partition rebalancing
+
+- **Test**: `TestAutoSplitMerge`
+  - Simulate high load to trigger auto-split
+  - Simulate low load to trigger auto-merge
+  - Verify data consistency during splits/merges

+#### 2.2 Broker Scaling
+- **Test**: `TestBrokerAddRemove`
+  - Add brokers during operation
+  - Remove brokers gracefully
+  - Verify partition reassignment
+
+- **Test**: `TestLoadBalancing`
+  - Verify even load distribution across brokers
+  - Test with varying message sizes and rates
+  - Monitor broker resource utilization
+
+### 3. Failover and Reliability Tests
+
+#### 3.1 Broker Failover
+- **Test**: `TestBrokerFailover`
+  - Kill leader broker during publishing
+  - Verify seamless failover to follower
+  - Test data consistency after failover
+
+- **Test**: `TestBrokerRecovery`
+  - Broker restart scenarios
+  - State recovery from storage
+  - Partition reassignment after recovery
+
+#### 3.2 Data Durability
