1Cover all paths:2□ Happy paths (everything works)3□ Edge cases (unusual inputs)4□ Error scenarios (things break)5□ Boundary conditions (limits)6□ Security cases (abuse attempts)Conversation Testing
Test Scenarios
Text
1For each intent, test:2- Standard request3- Variations in wording4- Missing information5- Extra information6- Corrections mid-flow7- Abandonment and returnExample Test Cases

1Build test suite:21. Create test cases file32. Input → Expected output43. Run automatically54. Compare results65. Report failures7 8Tools:9- Platform built-in testing10- Custom scripts11- CI/CD integrationConversation Analytics
Key Metrics
Text
1Volume metrics:2- Total conversations3- Messages per conversation4- Peak hours5- Growth trends6 7Performance metrics:8- Resolution rate9- Handoff rate10- First response time11- Time to resolution12 13Quality metrics:14- Intent accuracy15- User satisfaction16- Task completion rate17- Return rateIntent Analysis

1Track per intent:2- Volume3- Success rate4- Average turns to resolve5- Common follow-up intents6- Failure reasonsDrop-off Analysis
Text
1Where do users abandon?21. Track each step32. Identify high drop-off points43. Analyze why54. Improve those flows6 7Example:8Welcome → 95% continue9Ask email → 70% continue ← Problem!10Verify → 90% continue11 12Action: Simplify email collectionUser Feedback
Collecting Feedback
Text
1After conversation:2"Was I helpful today? 👍 👎"3 4On negative:5"I'm sorry! What could I have done better?"6 7Options:8- Thumbs up/down9- 1-5 star rating10- Text feedback11- Specific questionsAnalyzing Feedback
Text
1Aggregate:2- Overall satisfaction score3- Score by intent4- Score by time period5- Common complaints6 7Text analysis:8- Sentiment9- Keywords10- Themes11- Specific issuesOptimization Process

11. Analyze2 - Review metrics3 - Read conversations4 - Check feedback5 62. Identify Issues7 - Low performing flows8 - Common failures9 - User complaints10 113. Hypothesize12 - Why is it failing?13 - What would fix it?14 154. Implement16 - Update prompts17 - Add training data18 - Improve flows19 205. Measure21 - A/B test if possible22 - Track improvement23 246. RepeatPrompt Optimization
Text
1Improve AI responses:2 3Original prompt:4"Answer the user's question."5 6Better prompt:7"You are a helpful customer service agent.8Answer the user's question concisely.9If you don't know, say so.10Always offer additional help."11 12Test both, measure quality difference.Flow Optimization
Text
1Simplify flows:2- Reduce steps3- Combine questions4- Add shortcuts5- Remove unnecessary6 7Before: 5 steps to track order8After: 2 steps (ask number, show status)A/B Testing
What to Test
Text
1Test variations:2- Welcome messages3- Button labels4- Response wording5- Flow order6- Prompt templates7- Personality toneSetup
