[aojunhao123]

Summary by CodeRabbit

• Chores

  • 优化了版本控制设置，不再跟踪依赖项锁定文件，以提升项目管理效率。

• Tests

  • 加强了测试环境，新增了一项模拟机制，用于在测试过程中模拟元素尺寸变化，确保系统行为一致。

Walkthrough

此次更改在两个文件中进行：在 .gitignore 文件中新增了一行以忽略 package-lock.json 文件，从而防止其被 Git 跟踪；在 src/setup.ts 文件中新增了对全局 ResizeObserver 的 Jest 模拟实现，为测试环境提供了包含 observe、unobserve 和 disconnect 方法的模拟对象。整体结构未作其他修改。

Poem

嗨，我是一只兔，跳跃迎新改，
Git忽略新添锁定，不再烦拥杂，
ResizeObserver化身梦幻帮手，
测试顿时轻松无忧呵，
快乐编程快乐跑，🐇✨
欢快时光不停调。

Warning

There were issues while running some tools. Please review the errors and either fix the tool’s configuration or disable the tool if it’s a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

Oops! Something went wrong! :(

🪧 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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.

24-30: 建议增强 mock 实现以提供更好的测试能力

当前实现可以进一步改进以提供更完整的测试支持：

1. 添加类型定义和文档注释
2. 实现基本的错误处理
3. 跟踪被观察的元素

建议参考以下实现：

+// Mock implementation of ResizeObserver for testing environments
+// See: https://developer.mozilla.org/en-US/docs/Web/API/ResizeObserver
 global.ResizeObserver = jest.fn(() => {
+  const observedElements = new Set();
   return {
-    observe() {},
-    unobserve() {},
-    disconnect() {},
+    observe(element) {
+      if (!(element instanceof Element)) {
+        throw new TypeError('Failed to execute observe: parameter 1 is not of type Element.');
+      }
+      observedElements.add(element);
+    },
+    unobserve(element) {
+      observedElements.delete(element);
+    },
+    disconnect() {
+      observedElements.clear();
+    },
   };
 });

24-30: 基本实现正确且符合要求！

mock 实现包含了 ResizeObserver 所需的所有基本方法（observe、unobserve 和 disconnect），并使用了 jest.fn() 来创建可跟踪的模拟函数。
