## 🧪 Testing

### Quick Test

```bash
# Start application
mvn quarkus:dev

# Test status endpoint
curl http://localhost:8081/api/monitor/status

# Test health check
curl http://localhost:8081/health/live

# Trigger workflow
curl -X POST http://localhost:8081/api/monitor/trigger/scraper-import

# Test notification
curl -X POST http://localhost:8081/api/monitor/test-notification \
  -H "Content-Type: application/json" \
  -d '{"message":"Hello from Quarkus!"}'
```

### Docker Test

```bash
# Start with Docker Compose
docker-compose up -d

# Wait for startup
sleep 10

# Test health
curl http://localhost:8081/health/ready

# View logs
docker-compose logs -f

# Stop
docker-compose down
```

---

## 🔧 Troubleshooting

### Issue: Port 8081 already in use

```bash
# Change port
export QUARKUS_HTTP_PORT=8082
mvn quarkus:dev

# Or in application.properties
quarkus.http.port=8082
```

### Issue: Database not found

```bash
# Check path
ls -la C:/mnt/okcomputer/output/cache.db

# Create directory
mkdir -p C:/mnt/okcomputer/output

# Check permissions
chmod 755 C:/mnt/okcomputer/output
```

### Issue: Scheduler not running

```bash
# Enable debug logging
export QUARKUS_LOG_CATEGORY__IO_QUARKUS_SCHEDULER__LEVEL=DEBUG

# Check scheduler config
curl http://localhost:8081/q/dev/io.quarkus.quarkus-scheduler/scheduled-methods
```

### Issue: Health check failing

```bash
# Check logs
docker logs auction-monitor

# Test directly
curl -v http://localhost:8081/health/ready

# Verify database
sqlite3 C:/mnt/okcomputer/output/cache.db "SELECT COUNT(*) FROM auctions;"
```

   mvn package -Pnative
   ```

2. **Metrics** (add Micrometer)
   ```xml
   <dependency>
       <groupId>io.quarkus</groupId>
       <artifactId>quarkus-micrometer-registry-prometheus</artifactId>
   </dependency>
   ```

3. **OpenAPI** (API documentation)
   ```xml
   <dependency>
       <groupId>io.quarkus</groupId>
       <artifactId>quarkus-smallrye-openapi</artifactId>
   </dependency>
   ```

4. **Tracing** (distributed tracing)
   ```xml
   <dependency>
       <groupId>io.quarkus</groupId>
       <artifactId>quarkus-opentelemetry</artifactId>
   </dependency>
   ```
