# Simulating data (WIP)

This article lists and explains all available simulator functions.

In app development, the original data needed to test certain functionality might not be available during the building phase. In such instances, utilizing the simulator is a wise choice. The simulator provides a comprehensive set of functions, capable of generating various data types and random data.

To access the simulator, unfold `Simulation` > `Simulator` in the functionality panel.

## Simulator functions

Simulator functions do not differ from other [functions](/~/changes/eYCCpn9cCBKOYnZA6a8f/building-apps/data-processing/functions.md) in the way you can link, configure or extend them.

### Random integer

The `randomInteger` function generates random integers. You can specify a minimum and/or maximum value for the random integer using the `min:` and `max:` options in the input field.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.heisenware.com/~/changes/eYCCpn9cCBKOYnZA6a8f/building-apps/simulation-and-testing/simulating-data-wip.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
