Testing is the difference between a great agent and a frustrating one. Atoms gives you three ways to test, so you can catch issues before real callers do.

**Location:** Top right → **Test Agent** button

## Three Test Modes

<Tabs>
  <Tab title="Web Call">
    <Frame caption="Web Call test mode">

    </Frame>

    **Voice call in your browser.** Quick and convenient — no phone needed.

    Best for rapid testing during development.
  </Tab>

  <Tab title="Telephony Call">

    </Frame>

    **Real phone call.** The authentic experience — exactly what your callers will hear.

    Best for final validation before launch.
  </Tab>

  <Tab title="Chat">

    </Frame>

    **Text-only conversation.** Test conversation logic without voice.
