# Emulator

When your bot does not behave as expected, you need to investigate and identify the issue—also known as debugging. But where should you start? How can you determine the cause of the problem? This article covers the basics of debugging inside the Chatlayer Emulator. 

## Test your bot in the Emulator

To open your Emulator:

1. Under the [**Bot builder**](https://docs.chatlayer.ai/navigation/bot-builder) tab, click on [**Flows**](https://docs.chatlayer.ai/navigation/bot-builder/flows).
2. Find the **play** button in the upper right corner of the screen and click on it.
