Walkthrough

The changes introduce a comprehensive unit test suite for the ParticleRenderer component in the Galacean engine. Utilizing Mocha's syntax, the tests cover key properties, including lengthScale, velocityScale, and renderMode, validating their behavior with various inputs. Additionally, reference counting for the mesh property is thoroughly tested. This enhancement ensures the robustness of the ParticleRenderer, contributing to the stability and reliability of the rendering system.

Poem

In the engine’s heart, the particles dance,
With tests in place, they twirl and prance.
Lengths and velocities, all put to the test,
Ensuring our renderer performs at its best!
A hop, a skip, through code they gleam,
Reliable, robust—what a glorious dream! 🐰✨

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Could we change the title to case of ParticleRenderer mainModule to be more accurate?
