I get that. Testing components in particular is something I've rarely found to be worth it as well.

But often I find myself writing logic in the frontend, say for processing data from the API. That's where I want to create a file and write a unit test because it would actually be easier. Sadly for a small project the effort of configuring and maintaining updates of an external test framework on-top of Next makes no sense.

When using typescript, unit testing needs are few and far between.
