# Project Testing

This project includes various tests to ensure the correctness of the product. 

Test are segmented into two broad categories, **Unit Tests** and **Integration Tests.** By default all unit tests are enabled, and *most* Integration tests are also enabled, although certain classes of integration tests only run inside of the [CI environment](https://circleci.com/gh/sappenin/java-ilpv4-connector).

## Unit Tests

Each class in this implementation should have high levels of unit test coverage. Execution of these tests is orchestrated by the [Maven Surefire Plugin](https://maven.apache.org/surefire/maven-surefire-plugin/), and can be enabled or disabled via command line-switches as detailed below. By default, 

## Integration Tests

This project includes a single module housing all integration tests: [ilpv4-connector-it](https://github.com/sappenin/java-ilpv4-connector/tree/master/ilpv4-connector-it). By default, most integration tests execute in the local build environment, whereas *all* Integration tests execute in the CI environment.

There are various types of Integration test:

* **Performance ITs**: Validate the performance characteristics of the product.
* **IlpOverHttp ITs**: Validate functionality of two or more nodes peering with each other using [ILP-over-Http](https://github.com/interledger/rfcs/blob/master/0035-ilp-over-http/0035-ilp-over-http.md).
* **Settlement ITs**: Validate functionality of the Settlement subsystems using multiple nodes.

# 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://connector.interledger4j.dev/contributing/project-testing.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.
