The **Test** tab lets you chat with the draft of your agent before you publish it. Tools run in test mode, so nothing is sent or changed.

## Before you start

- You need the **Owner** or **Admin** role.
- The test saves your edits to the draft first.

## Test the draft

1. Open **Agents**, then select **Manage agent** on the agent.
2. Open the **Test** tab.
3. Select a channel, for example **SMS** or **Call**. Only the channels that the agent works on show.
4. Select **As a customer** or **As your team**.
5. Type a message, then select **Send**.
6. Read the reply. Turn on **Steps** to see each step the agent took, such as a knowledge search or a tool call.
7. Select **Start again** to clear the chat.

For **Call**, type what the caller says. The test checks what the agent says and does. It does not test the voice or speech recognition.

## What a test does not do

A test does not send a message, change a record, create a work item or use credits. Tool calls show the action that the agent would take.

## Fix the checks

The **Checks** card on the **Test** tab lists setup problems. A blocking check stops a publish.

- When a check fails, the card shows how many checks you must fix.
- When all blocking checks pass, the card shows **Ready to publish**.

The checks test the setup. They do not test if the answers are correct.

## Test it live

After you publish the agent and the workflow, test with a real call or message.

1. Call or text your Line number from a phone that is not in your team.
2. Open **Agents**, then select **Manage agent** on the agent.
3. Open **Activity**.
4. Open the run to see each step.

## Review a run

You can record if the agent got it right.

1. In **Activity**, open the run.
2. Select **Review**.
3. In **Outcome**, select **Resolved**, **Needs follow-up**, **Incorrect** or **Unsafe**.
4. Optional: add a **Note**.
5. Select **Save review**.

## Common problems

**The test replies, but customers get no reply.** The test uses the draft. Customers get the published version, and only through a workflow. Publish the agent, then check that a workflow has an **Agent** step for it. See [Agent not answering](https://useline.io/help/troubleshooting/agent-not-answering).

**A channel is missing in the Test tab.** Turn the channel on under **Where does the Agent work?** in the **Identity** tab.
