Show HN: Fake-xmlservice – Local XmlService implementation for GAS testing

1 point

8 months ago

I often write Google Apps Script (GAS) projects that rely on XmlService, but I found it hard to test them locally. So I created @yoshi389111/fake-xmlservice, an npm package that implements XmlService in Node.js.

- Works with Jest (e.g., put it in `setupFilesAfterEnv`)

- Allows local unit tests for GAS code using XmlService

- Supports parsing and serializing XML (partially complete, not 100%)

- API is designed to be a drop-in replacement for GAS's XmlService

Repo: <https://github.com/yoshi389111/fake-xmlservice>

Package: <https://www.npmjs.com/package/@yoshi389111/fake-xmlservice>

It's not fully complete yet, but it already works for my use cases. I'd love feedback on:

- What features you'd expect in a testing library for GAS XmlService

- Any edge cases you ran into with XmlService in your projects

Thanks!
