Introduction to Kaolin

Kaolin is an innovative open-source project developed by NVIDIA that focuses on 3D integration testing, particularly for the experimental Dash3D framework. With a robust codebase comprising 898 files and over 438,024 lines of code, Kaolin aims to streamline the testing process for 3D applications, ensuring high-quality outputs and efficient workflows.

Key Features of Kaolin

• High-level Integration Testing: Focuses on ensuring that various components of the Dash3D framework work seamlessly together.
• Support for Multiple Testing Frameworks: Utilizes pytest, Mocha, and Cypress for comprehensive testing capabilities.
• Extensive Documentation: Provides clear guidelines for installation, usage, and contribution.
• Community Contributions: Encourages developers to contribute to the project, enhancing its functionality and robustness.

Technical Architecture and Implementation

Kaolin’s architecture is designed to facilitate integration testing for 3D applications. The project is built on a foundation of Python and JavaScript, allowing for a flexible and powerful testing environment. The integration tests are primarily wrapped in Python, which calls JavaScript tests, ensuring a seamless interaction between the two languages.

Testing Frameworks

Kaolin employs several testing frameworks:

• Pytest: Used for running integration tests.
• Mocha: Handles JavaScript tests that can run outside of the browser.
• Cypress: Facilitates end-to-end testing that requires a browser.

Setup and Installation Process

To get started with Kaolin, follow these steps:

1. Install Node.js

conda install -c conda-forge nodejs

2. Install Frontend Dependencies
