Not sure if that can be applied in this context (when/where the test runs) but wouldn't an npm install with a relativlely recent npm version and a git diff achieve the same with a bit more variety of possible mismatches/errors?

@mstruebing I think there is a value in having this all run during npm run test

I suppose we could shell out and run those commands, but that would potentially modify the user's environment (via the npm install) so I'm not positive that it is a good idea.

Open to suggestions though.

Also, I'm not sure why the tests are failing...

[brendandburns]

I think there's a separate lint failure that got introduce somehow, I will try to fix it in a different PR.

[mstruebing]

tests are passing 🙌
