Test Scenarios
Run through these common scenarios:Happy Path
Test the ideal conversation flow:- Start with a greeting
- Follow the expected conversation
- Complete the intended goal
- End the call naturally
Edge Cases
Test unexpected situations:- Asking off-topic questions
- Providing invalid information
- Requesting human transfer
- Long pauses/silence
Stress Testing
Push the boundaries:- Speak quickly
- Interrupt the agent
- Ask complex questions
- Try to confuse the AI
Reviewing Results
After the test:- Review transcript - Check for accuracy issues
- Note timing - Mark slow or awkward moments
- Identify failures - Document where flow broke
- Test fixes - Make adjustments and retest
Troubleshooting
| Issue | Solution |
|---|---|
| No audio from agent | Check speaker settings, verify voice is configured |
| Agent doesn’t hear me | Check microphone permissions and selection |
| Delayed responses | Normal for AI processing; check responsiveness setting |
| Wrong transitions | Review transition conditions |
| Inaccurate responses | Check knowledge base attachment and system prompt |
Best Practices
Test Incrementally
Test each section as you build, not just at the end.
Document Issues
Keep notes on what doesn’t work so you can fix it.
Test Multiple Times
AI responses vary. Test the same scenario several times.
Use Real Scenarios
Test with questions real customers would ask.
