# Test an agent before going live

> Use Jaaxis Preview to test answers, inspect sources, find knowledge gaps, and verify behavior before connecting customers.

Preview lets you test the customer experience without mixing test messages into a live customer conversation.

Open **Agents**, choose an agent, then select **Preview**.

## Build a representative test set

Include:

* Common questions with one clear answer.
* Questions where conditions change the answer.
* Misspellings and short conversational wording.
* A question that is not covered by your knowledge.
* A request for a person.
* A blocked-word case.
* Each enabled booking flow.

## Inspect the answer

For knowledge-based replies, open **Sources** and confirm the cited item actually supports the answer. A fluent answer is not enough if the source is unrelated or outdated.

## Fix the right layer

| Problem                           | Change                                     |
| --------------------------------- | ------------------------------------------ |
| Wrong fact                        | Update Knowledge                           |
| Missing fact                      | Add Knowledge                              |
| Wrong tone or response style      | Update Persona                             |
| Handoff happens too early or late | Update Forwarding rules                    |
| A tool is used incorrectly        | Update the tool or its linked instructions |
| Widget appearance is wrong        | Update Appearance or Settings              |

## Repeat after every important change

Retest the original failure and one nearby case. This confirms the correction without creating a new problem.

<Tip>
  Use real wording copied from support conversations after removing names, email addresses, order numbers, and other personal data.

When your core questions, handoffs, and tools behave correctly, continue to [connect a customer channel](/en/connect/overview).
