Business value

You can test and debug actions in your agents before you publish them. Testing helps you handle issues or unexpected behavior in how actions work.

Feature details

This feature improves how you test and improve your actions when you build agents:

Enhanced testing experience: By providing clear and actionable testing information, the feature helps you understand and implement the necessary steps without confusion. This experience ensures you maintain the context of your ongoing tasks in Copilot Studio or Microsoft 365, leading to a more seamless workflow.

Debugging and recommendations: Plugin run history, in-line recommendations, and workflow visibility are invaluable features. These tools help you trace issues, understand exceptions, and make effective improvements to your actions. This comprehensive approach to debugging quickly identifies and resolves problems, enhancing the overall efficiency of the development process.

Simulated test data: When you create a set of test data, you can verify the functionality of your actions in a controlled environment. This step is crucial for ensuring correctness and reliability before live deployment. By testing in a simulated environment, you can confidently deploy your solutions, knowing they're vetted for potential issues.
