# Test on Simulator

Kalipso has an integrated Simulator where you can test your applications before deploying it to a mobile device. This feature helps you to be more productive while creating your applications. Kalipso Simulator is the same framework that runs your applications on a mobile device, compiled for Windows 32, which guaranties that your application is executed the same way that on a mobile device, except for some clearly marked Actions that only work in Windows Mobile or Windows CE or Desktop.

Kalipso Simulator is not an Emulator!

Kalipso Simulator allows you to forget about an eventual synchronization process when working offline, because you can automatically "Send Data" and "Erase Data" on Simulator.

* **Yes, Generate Data File** - If you check this option your Project, Kalipso Designer will fetch the data of the server, from the tables defined as "ToPDA" in their properties, and send it along with the Project. This option is only available if you have offline Database Tables.
* **Erase Data on Simulator** - If you check this option, it means that before integrating your Project, Kalipso will clear it from the Simulator as if never existed, including data.
* **Trace Actions** - This option allows you to debug your Project, by showing you all the Actions being executed as well as their parameters values.
* **Trace Variables** - This option allows you to to trace the content of the variables in runtime.

Combine these features with the ["Breakpoint](/kalipso5/developing/form/actions/actions-description/group-code-flow/breakpoint.md)" Action to run your Project step by step.
