Do you mean build simple site as Jest test? We had something like that in v1. https://github.com/facebook/docusaurus/blob/docusaurus-v1/packages/docusaurus-1.x/lib/__tests__/build-files.test.js

Yes, this kind of test can probably be done after the end of the e2e workflow, not sure where to put the files though because it shouldn't execute by default when running yarn test

Prettier has a separate repo with fixtures for testing new releases. Maybe we can make a mock site repo as well🧐
