 #### Tests
 
-Tests can be scoped via `jest --selectProjects {project}`. Refer to [jest's config](./jest.config.js) for project names.
-
-> :warning: You need `NODE_OPTIONS=--experimental-vm-modules` in your environment for `jest` to [parse ESM](https://jestjs.io/docs/28.x/ecmascript-modules#differences-between-esm-and-commonjs). Optionally, use [direnv](https://direnv.net/) for local setup of environment variables.
-
-Example test command for client watch mode:
-`NODE_OPTIONS=--experimental-vm-modules yarn jest packages/client/src/index.test.js --watch --verbose=false`
-
-Example test command for provider-elasticsearch watch mode:
-`NODE_OPTIONS=--experimental-vm-modules yarn jest packages/provider-elasticsearch/test/index.test.js --watch --verbose=false`
+Tests can be scoped via `vitest --project {project}`. Refer to [vitest's workspaces](./vitest.workspace.ts) for project names.
