A clean 7-step workflow to auto-test any voice agent (free SOP)

🔥

I’ve built and delivered custom AI voice agents for 15+ clients, and this is the exact 7-step system I use to automate all testing so you don’t waste 5–10 hours manually calling your agent every time you update it.

Hi all—testing voice agents takes way more time than most people expect.

And I know a lot of you here are still testing everything by hand.

I recently cleaned up my internal QA workflow and turned it into a simple, repeatable process.

Here’s how you can set it up for your own builds:

Export your entire voice agent as a JSON file from Retell/Vapi.
Upload that JSON + any knowledge base files into your LLM workspace.
Paste in the system prompt (I shared it in the video + SOP).
Let the LLM analyze all branches, nodes, intents, and fallbacks.
Auto-generate 15–25 test cases covering emergency, spam, billing, scheduling, objections, retrieval accuracy, and more.
Download the output as a JSON file.
Import it straight into Retell Simulations and run everything in one click.
