Module 15: Copilot Studio Fundamentals
Lesson 15.5: Testing and Improving Your Agent
Lesson Promise
Create a repeatable testing loop before and after publication.
Real-World Scenario
The FAQ agent works in demos but fails when users ask vague, misspelled, or multi-part questions.
Core Concept
Testing should reflect real user language, not only the exact wording the builder expected.
Improvement comes from test logs, user feedback, analytics, and content-owner review.
A published agent needs lifecycle habits: monitor, fix, retest, communicate changes, and revisit governance.
Step-By-Step Workflow
- Create a test set from real user questions.
- Include vague, multi-intent, misspelled, and out-of-scope prompts.
- Record expected answer, actual answer, source behavior, and fix needed.
- Review analytics and user feedback after launch.
- Update topics, knowledge, or instructions.
- Retest before communicating improvements.
