# Add a New Test Library

Test libraries in Akto allow you to expand and customize your API testing capabilities. This guide will walk you through the process of adding a new test library to your Akto instance.

### Adding a New Test Library

### Configuring the New Test Library

1. Repository URL:
   * Enter the URL of the zip file containing your test library YAML files.
   * Example: \`[`https://github.com/akto-api-security/tests-library/archive/refs/heads/feature/input_validation_test_1.zip`](https://github.com/akto-api-security/tests-library/archive/refs/heads/feature/input_validation_test_1.zip)
2. File Size Limit:
   * Ensure your zip file is less than 10 MB in size.

### Post-Addition Steps

1. Once added, your new test library will appear in the list of available test libraries on the Test Library page.
2. You can now use the tests from this library in your API testing workflows.

### Troubleshooting

* If the "Add" button doesn't respond, double-check the URL format and accessibility.
* If you encounter errors after adding the library, verify the content and format of your YAML files.

By following these steps, you can easily expand Akto's testing capabilities with your own custom test libraries or third-party test collections.

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://docs.akto.io/test-editor/how-to/add-a-new-test-library.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.
