This integration provides the ability to run tests within the same runtime as Cloudflare Workers in production, allowing for greater confidence in the behavior of Workers when deployed. The integration also includes features like hot-module-reloading, watch mode, and per-test isolated storage. Developers can get started with testing Workers via Vitest by using the create-cloudflare tool or by manually installing and setting up the Workers Vitest integration. ## Full article daily.dev links to this article rather than hosting it.
