# Test an Agent

> Talk to the agent directly in the browser – without a real call.

Before an agent goes live, you should try it out. With the **test call**, you talk to the agent directly in the browser – through your microphone, entirely without the phone network.

## What the test call checks

The test call runs **live against your current draft**. Changes to the flow therefore take effect immediately in the next test, without you having to publish. This lets you iterate quickly.

<Note>
  Test calls create **no** logged call and no entry in the call analysis – they serve solely for trying things out.
</Note>

## Starting a test call

<Steps>
  <Step title="Open the test view">
    For the agent's draft, open the **Test call** view.
  </Step>

  <Step title="Grant microphone access">
    Allow the browser access to your microphone. The connection is established.
  </Step>

  <Step title="Speak">
    Talk to the agent like a real caller. You hear its responses and see the conversation live.
  </Step>
</Steps>

## The test interface

During the test, you see three areas side by side:

<CardGroup cols={3}>
  <Card title="Flow state" icon="diagram-project">
    Shows live which state of the flow the agent is currently in.
  </Card>

  <Card title="Live chat" icon="comments">
    The ongoing conversation as text – your inputs and the agent's responses.
  </Card>

  <Card title="Event log" icon="list">
    Technical events such as tool calls, results, and state changes.
  </Card>
</CardGroup>

<Tip>
  In the event log, pay particular attention to the **tool calls** and **state changes** – this lets you quickly see whether your transition conditions take effect as intended.
