How do you test an Agentforce agent in Agent Builder and what should you validate?

Agent Builder provides a built-in test conversation panel for testing agents before deployment. Testing approach:

1. Test conversations: Enter real user messages and observe the agent's full reasoning trace — which Topic was classified, which Action was invoked, what parameters were passed, and what response was generated.
2. Expected Topic validation: Verify that each test utterance maps to the intended Topic. If the wrong topic is selected, revise the topic description or scope to reduce ambiguity.
3. Expected Action validation: Verify that within the correct topic, the correct action is invoked with correctly extracted parameters. If parameters are wrong, improve the action's description or input variable descriptions.
4. Edge cases: Test ambiguous, out-of-scope, and adversarial inputs to verify the agent handles them gracefully — either routing to a fallback, asking clarifying questions, or escalating.
5. Action output handling: Verify the agent correctly uses action output in its response — not ignoring results or misinterpreting them.
6. End-to-end data accuracy: Confirm that data retrieved from Flows or Apex matches expectations — test with real sandbox records.
