Our Commentary ​

Vitest continues to impress with its rapid development. The UI improvements for tracing and coverage are a big win for developer experience. I'm particularly interested in how the new IstanbulJS packages will affect coverage reporting. It's good to see them pushing towards a stable v5 with such thoughtful features.
