Fake-xmlservice – Local XmlService implementation for GAS testing

Hacker News

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!
