Walkthrough

The pull request focuses on refactoring the test suite for the Leaderboard component in Leaderboard.spec.tsx, migrating from Jest to Vitest. The changes involve updating mocking mechanisms, specifically for the useParams hook from react-router-dom, and adapting the test setup and teardown hooks to work with Vitest. The modifications ensure compatibility with the new testing framework while maintaining the existing test coverage and scenarios.

Changes

File Change Summary
src/screens/Leaderboard/Leaderboard.spec.tsx - Replaced Jest mocking with Vitest mocking
- Updated useParams hook mocking
- Replaced beforeAll/afterAll hooks with Vitest equivalents
- Enhanced documentation comments

Assessment against linked issues

Objective Addressed Explanation
Replace Jest-specific functions with Vitest equivalents [#2553]
Ensure tests pass using npm run test:vitest [#2553] Requires full test suite verification

17-17: LGTM: Vitest import added correctly

The vi import from 'vitest' is properly added, which is necessary for the migration from Jest to Vitest.


19-37: LGTM: Well-documented test suite

The JSDoc comment provides comprehensive documentation of test scenarios, mock setups, and key test cases. This documentation will be valuable for maintaining and understanding the test suite.


86-92: LGTM: Test setup correctly migrated to Vitest

The test setup has been properly migrated:

  • vi.mock correctly preserves the original module functionality while mocking useParams
  • vi.clearAllMocks is appropriately used in the cleanup phase

Also applies to: 96-96


100-100: LGTM: Test cases successfully migrated to Vitest

All test cases have been consistently migrated to use Vitest's mocking pattern:

  • vi.mocked(useParams).mockReturnValue() is correctly used throughout
  • The implementation is consistent across all test cases
  • The mocking approach properly maintains the test scenarios

Also applies to: 124-124, 133-133, 164-164, 185-185, 208-208, 229-229, 250-250, 267-267, 282-282, 292-292


Line range hint 1-299: Verify complete migration from Jest to Vitest

Let's verify that no Jest references remain in the codebase:

✅ Verification successful

Migration to Vitest is complete and correct

The verification confirms that:

  • All test utilities are properly imported from Vitest (vi) and Testing Library
  • All mocking functionality uses Vitest's vi.mock() and vi.mocked()
  • No Jest-specific imports, methods, or references remain
  • Test structure uses standard testing patterns compatible with Vitest
  • All assertions use Testing Library's expect syntax
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for any remaining Jest references in the file
rg -i "jest\." "src/screens/Leaderboard/Leaderboard.spec.tsx"

# Search for any potentially missed Jest imports
rg -i "from ['|\"]@?jest" "src/screens/Leaderboard/Leaderboard.spec.tsx"

Length of output: 136


Script:

#!/bin/bash
# Search for any test-related imports and assertions to verify complete migration
rg -i "import.*test" "src/screens/Leaderboard/Leaderboard.spec.tsx"

# Look for any expect statements to verify testing framework
rg "expect\(" "src/screens/Leaderboard/Leaderboard.spec.tsx"

# Check for any testing-related functions or methods
rg -i "describe|it|test|beforeAll|afterAll|mock" "src/screens/Leaderboard/Leaderboard.spec.tsx"

# Search for any remaining testing framework references

    • 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.
