Meta Is Transferring Jest to the OpenJS Foundation
Jest has been pretty wonderful to work with over the last few years. Like any test framework, however, there are real pain points.I've recently started experimenting with Vitest on a new webapp using Vite/React. It's API compatible with Jest, but integrates with your existing build tool-chain instead of forcing you to configure a parallel one. So far, there's a lot to like. 
https://vitest.dev/The `--ui` flag showing a visualization of the dependency graph of a test is probably my favorite little feature.
