Frequently asked questions
What are AI simulations?
AI simulations let an AI play the customer through part of a test conversation. Define the scenario, success criteria and maximum turns. The simulation passes when it reaches those criteria within the turn limit.
Do tests run automatically when I edit an agent?
No. Start a single test or a batch yourself. Automated here refers to simulated conversations and checks; it does not mean every edit triggers a test run.
What can a test verify?
Check the response with exact matching or an LLM judge, verify routing to a playbook or workflow, and check that the expected tool was called.
Can I test different customer contexts?
Yes. Personas supply saved starting variable values, and a launch event can change how a test starts. Simulations let an AI play the user toward success criteria within a turn limit.
Do test runs use credits?
LLM-powered activity in tests consumes credits, as it does in a real conversation.
