# Featured projects

## libp2p

libp2p is an open source networking stack and library modularized out of The IPFS Project, and bundled separately for other tools to use. You can find the libp2p Testground plans in the [Testground Plans Repository](https://github.com/libp2p/test-plans/).

## Testground learning example

This project is intended as a practical example of a "real" project, with its own internal business logic, dependencies, etc. The logic and behaviors are intended to be as straightforward as possible, acting as a reference / guide on how to implement these behaviors and test them using Testground.

You can find the project in the following Github repositories:

* [Learning project](https://github.com/testground/learning-example)
* [Testground plans](https://github.com/testground/learning-example-tg)

**Featured test cases**

* Running a build with the `docker:generic` builder, a custom `Dockerfile` and `manifest.toml`
* Running an additional docker container as a dependency for tests (see the `Makefile` for an example)
* Test cases which are intentionally written to fail, due to a context timeout, or a network routing policy that causes a node to be unreachable

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://protocol-labs.gitbook.io/testground/table-of-contents/featured-projects.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.
