Topic 8: Real-World Testing

What You’ll Learn

This topic teaches you how to:

  • Conduct user acceptance testing
  • Run A/B tests with agents
  • Use shadow mode evaluation
  • Deploy canary releases
  • Monitor production performance

Why We Need This

Business Need

  • User validation: Real users validate agent quality
  • Risk reduction: Test in production safely
  • Data-driven decisions: A/B test agent improvements

Technical Need

  • Production testing: Test in real environment
  • Gradual rollout: Deploy safely
  • Monitoring: Track real-world performance

Industry Use Cases

1. Canary Deployments

Company: All production systems Use Case: Gradually roll out new agents

2. A/B Testing

Company: Tech companies Use Case: Compare agent versions

3. Shadow Mode

Company: Risk-averse companies Use Case: Test agents without affecting users
