The AgentForce Testing Center Functional Overview highlights that AI-powered synthetic test utterances allow teams to automatically generate natural language variations of existing test prompts. This feature helps validate whether the agent can correctly classify and respond to diverse user phrasing — a crucial step in ensuring conversational robustness and intent coverage.

By expanding each test case into multiple paraphrased utterances, the Testing Center evaluates how well the reasoning engine generalizes user intent, improving reliability before deployment.

Option B is insufficient because manually written prompts cover limited language diversity. Option C waits for live feedback, which exposes end users to unvalidated agent behavior and is not a pre-deployment testing method.

Therefore, the correct choice is Option A – AI-generated synthetic test utterances based on natural language variations.
