Short answer: yes—this already exists via the Agents API. You can run simulated conversations and define the “simulated user” with your own prompt using the simulate-conversation (batch) or simulate-conversation/stream endpoints. Pass the simulated_user_config with a PromptAgent prompt in simulation_specification. (elevenlabs.io)
Regarding a UI “Test” feature in the alpha: the public docs don’t announce a UI control for user‑prompted simulations or give a roadmap. The product page references Workflows & Testing (and “Test guardrails”), but only Multi‑agent workflows is explicitly marked “Coming soon.” No additional UI details are documented. (elevenlabs.io)
If you need this today, use the API pages above; the guide shows concrete SDK examples with a user prompt. (elevenlabs.io)
