Poem

🐰 In the realm of tests, a rabbit hops with glee,
From Jest to Vitest, code now runs free!
Mocks dance, assertions sing,
A testing transformation that makes hearts spring!
Base64 encoded, coverage bright and clear! 🧪✨

  • 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.

20-20: Mocking FileReader is properly implemented.

Using vi.spyOn(global, 'FileReader') ensures the effect is confined to this test. If you need to mock FileReader in multiple tests, consider a common setup in a beforeEach block for improved maintainability.

1-1: Great job replacing Jest imports with Vitest imports.

The updated imports from vitest look correct. Ensure that no Jest-specific imports or methods remain anywhere in the codebase to avoid confusion or potential conflicts.


33-33: Good cleanup practice.

Restoring the mocked FileReader helps prevent test pollution, ensuring that subsequent tests remain unaffected.
