Hello Kavyasri,
With generative bots and generative responses, "Response Match" is not ideal test type as responses are non-deterministic, and with "Response match" the response needs to be exact the expected, or otherwise the test case will fail. "Generative answers" test type is more ideal for this purpose, as it uses AI Builder and LLM to validate the generative response.
We are also releasing the next version of the Copilot Studio Kit very soon, and we have added support for additional comparison operators such as "contains" which might also work in your scenario. It allows checking if the response contains required keyword(s), ignoring everything else, and then passing or failing the test based on that. Great for templatized (dynamic) responses, and in some cases for generative responses as well.
Hope this helps.
