Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request undertakes a significant refactoring of the project's testing infrastructure by migrating from Vitest to rstest. This change aims to leverage the features and performance benefits of the rstest framework, streamlining the testing process and ensuring future compatibility. The migration involved updating core test configurations, dependencies, and adapting existing test files to the new framework's API, while maintaining the integrity and coverage of the test suite.

Highlights

• Test Framework Migration: Migrated the test suite from Vitest to rstest, updating configuration files, script commands, and test utility functions across the codebase.
• Dependency Updates: Updated package.json to replace Vitest-related development dependencies with their rstest and rsbuild equivalents, ensuring compatibility with the new testing environment.
• Snapshot Format Update: Updated all existing snapshot files to reflect the change from Vitest to Rstest, ensuring consistency with the new testing framework.
• SSR Test Environment Configuration: Introduced a new rstest.config.mts file to define rstest configurations, including specific settings for client and server-side rendering (SSR) test environments.

Code Review

This pull request migrates the project's testing framework from Vitest to Rstest. This involved updating package dependencies, modifying test scripts, and replacing Vitest-specific utility calls (e.g., vi.fn() to rs.fn()) across numerous test files. A new rstest.config.mts file was added, and existing snapshot headers were updated to reflect the change. A minor improvement opportunity was noted in the rstest.config.mts file regarding a redundant include property.
