# Testing

The Playground lets you run the current draft of an Agentic Flow interactively without publishing it.

[![Agentic Flow Playground testing interface](../images/agentic-playground.png)](../images/agentic-playground.png)

It is only available when the flow contains at least one **Input** component and one **Output** component.

## Opening the Playground

Click the **Playground** button (play icon) in the top-right of the editor header. A dialog opens with a chat-style interface connected to the live flow draft.

Send a message in the Playground to trigger the flow. The response is rendered when the Output component returns a result. Intermediate node outputs are not shown in the Playground view — use the Conversations tab after publishing for step-level traces.

## Playground Availability

The Playground button is disabled if the flow has no Input or Output component. A tooltip explains: *“Add an Input or Output to use the playground.”* Once both are present, the button becomes active.

## Variables and Context

Variables defined in the Variables drawer are available to the flow during Playground runs. You can set variable values before running to test different scenarios.
