Question

A Business Solutions Architect is finalizing the test plan for a Copilot Studio agent that calls three connectors (Dynamics 365 Sales, an external MCP inventory system, and a Power Automate approval flow). During a design review, the QA lead asks how the team should validate what happens when the external MCP inventory system times out mid-conversation. The architect wants test coverage that verifies the agent behaves correctly under this condition rather than only checking happy-path outputs. Which type of test case should the architect prioritize adding to the test plan?

Accepted Answer

A negative/failure-path test that simulates the MCP timeout and asserts the agent invokes its fallback behavior and returns a graceful, non-hallucinated response

Answer

A groundedness test that measures whether the agent's factual responses are supported by the connected knowledge sources

Answer

A load test that runs 500 concurrent conversations to measure the agent's average response latency

Answer

A regression test comparing the current agent version's outputs against the previous version's baseline responses
