🦉 Directory Traversal

[TricentisDevOps]

This major upgrade from Vitest v2 to v3 introduces several breaking changes that will likely require code and configuration adjustments.

Key Breaking Changes:

• Reporter API Redesign: The public API for custom reporters has been completely redesigned. Several hooks like onTaskUpdate and onFinished have been removed and replaced with a new lifecycle API. Custom reporters must be updated to conform to the new structure. [1, 5]
• Fake Timers Behavior: The default behavior for fake timers has changed. Previously, only a specific list of timers was faked. In v3, all timing APIs are faked by default. This may require removing or adjusting fakeTimers configurations in your vitest.config.js to prevent test failures. [9]
• Spy Behavior Changes: The behavior of spies has been modified. spy.mockReset() now restores the original implementation, and vi.spyOn() will reuse an existing mock if a method has already been spied on. [3, 8]
• Vite Version Support: Vitest v3 adds support for Vite 6 and requires a newer version of Vite (likely v5+). [3, 9]

Recommendation:
This upgrade requires careful review. Developers should consult the official migration guide, paying close attention to the sections on reporters, fake timers, and spies. Thoroughly test your suite after upgrading to catch any regressions caused by these behavioral changes.
