chore: add testToStringParseEmpty Test

[caicancai]

Motivation:

Null and Empty are two concepts. Configuration has a handle for Empty. I think it is possible to add a test description.

Modification:

Describe the idea and modifications you've done.

Result:

Fixes #.

Walkthrough

A new test method, testToStringParseEmpty(), has been added to the ConfigurationTest class in the ConfigurationTest.java file. This new method ensures that parsing an empty configuration string is properly validated, enhancing the robustness of the JRaft configuration handling.

Poem

In the realm of code, where tests reside,
A new method joins the testing tide.
To parse the void, the empty space,
Ensuring robustness keeps its pace.
🎉 Cheers to stronger, safer builds! 🎉

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.

31-42: Well-structured test method for empty configuration parsing.

The newly added testToStringParseEmpty method is well-structured and effectively tests several aspects of the Configuration class when an empty configuration string is provided:

• It verifies that the configuration is indeed empty.
• It checks the string representation of an empty configuration.
• It ensures that the parsed configuration from an empty string remains unchanged.
• It confirms the consistency of hashCode and equality methods for configurations initialized differently but representing the same state.

This comprehensive approach ensures that the class behaves as expected in edge cases, which is crucial for maintaining robustness in the configuration parsing logic.
