I would like to share with you an example where I demonstrate how you can write tests for your nodes using Vitest

> **[GitHub - AllanOricil/nrg-template: Build Node-red nodes using ES6+ and esm module...](https://github.com/AllanOricil/nrg-template)**
>
> Build Node-red nodes using ES6+ and esm module system with the nrg cli

obs: node-red-node-test-helper is still locked to this [commit](https://github.com/node-red/node-red-node-test-helper/commit/949edd23270b26b261f0f9b6596b548d5f80a6d4) because my changes to enable vitest were not released yet

obs: unit tests are still being written

obs: i'm also trying to enable e2e testing using playwright with multiple browsers. You can use `npm run test:e2e` but it wont test anything useful yet. At least the configuration is fine.
