The primary change involves replacing the test function with the it function across all three test cases in the file. The modifications maintain the existing test structure and assertions, ensuring that the test functionality remains consistent while aligning with the Vitest testing framework.

    • @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.

7-13: Conversion to Vitest it block looks correct.

The replacement of test with it aligns properly with Vitest standards, and all expectations remain inside the block. The ESLint "jest/no-standalone-expect" rules might be misfiring if they aren't configured for Vitest yet.

14-20: Second test block also appears correctly migrated.

No other changes are shown here besides switching to Vitest. This is consistent and does not break the existing testing logic.

All expect statements remain within the it block, indicating correct usage. Implementation follows the same pattern as above.

4-5: Consider importing cleanup utility

While migrating to Vitest, consider importing and using the cleanup utility from @testing-library/react to ensure proper test isolation.

import { render, screen } from '@testing-library/react';
+import { cleanup } from '@testing-library/react';
import Loader from './Loader';
import { describe, it } from 'vitest';

+afterEach(() => {
+  cleanup();

Line range hint 7-26: Test migration looks good!

The conversion from Jest's test() to Vitest's it() has been done correctly while maintaining the existing test structure and assertions. All test cases are properly contained within the describe block and follow consistent patterns.

💡 Codebase verification

ESLint configuration needs to be updated for Vitest

The ESLint configuration currently includes Jest-specific settings (plugin:jest/recommended and jest plugin) but lacks Vitest configuration. Since you're migrating from Jest to Vitest, you should:

  • Remove "plugin:jest/recommended" from extends array
  • Remove "jest" from plugins array
  • Remove Jest-specific rules
  • Add Vitest ESLint plugin and configuration

Specific locations that need attention:

  • .eslintrc.json:
    • Line 11: Remove "plugin:jest/recommended"
    • Line 27: Remove "jest" from plugins array
    • Line 93: Remove "jest/expect-expect": 0

The package.json shows that Vitest is already installed ("vitest": "^2.1.5"), but the ESLint plugin for Vitest is missing. You'll need to install eslint-plugin-vitest and update the configuration accordingly.

🔗 Analysis chain

Update ESLint configuration for Vitest

The ESLint errors about expects being outside test blocks are likely due to Jest-specific ESLint rules. Consider updating the ESLint configuration to use Vitest-compatible rules.

Run this script to check the ESLint configuration:

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check ESLint configuration for Jest rules that need to be updated for Vitest

# Search for Jest-related ESLint configurations

# Check for existing Vitest ESLint plugin in package.json
rg -l "eslint-plugin-vitest" package.json

Length of output: 84


Script:

#!/bin/bash
# Let's check the actual content of the ESLint configuration
cat .eslintrc.json

# Also check if there are any Vitest-related ESLint configurations already in place
rg -l "vitest" .eslintrc*

# Check package.json for both Jest and Vitest dependencies
