Walkthrough

此次更改向 Hash 测试套件中添加了一个新测试案例，旨在验证 HIncrBy 方法在处理不正确元数据时的功能。新测试确保在不同条件下对哈希字段进行增量操作时，系统的行为符合预期，这增强了哈希处理逻辑的稳健性。

Poem

🐇 在哈希的世界里，
增量增添乐趣多，
元数据若不齐，
兔子也要来捣乱！
测试案例新增加，
稳健逻辑伴我行。 🍃

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.

测试名称应准确描述测试的目的和预期行为。

建议将测试名称改为更具描述性的名称，例如 It("HIncrBy should handle incorrect metadata correctly")。

202-204: 检查增量操作

增量操作和断言看起来很好，但可以考虑添加更多边界条件测试。

---

206-208: 删除键值

删除键值的操作和断言是合理的。

---

210-212: 检查删除后增量操作

删除键值后再次进行增量操作的测试是合理的。
