react ts app `yarn test:unit` fails with `SyntaxError: Cannot use import statement outside a module` about vite-jest

I am getting a very similar issue specifically when testing React components following the same example. In this case, react-hook-form seems to be the offender.

I can post more details if that is helpful

Maybe more related to #11 though now that I read through it

Edit: for clarification this is using npm v7.19.0

I think this is a Yarn 2 specific problem, and to be more specific this is because Yarn 2 cannot currently run ES Modules.

See yarnpkg/berry#638

When I try to run the example with pnpm it works, but not using yarn

@mijamo The error in my screenshot was with npm v7.19.0. I have not tried pnpm, although I did observe the same issue with Yarn 2 as you indicated as well.
