Those files shouldn't be inside the npm package. Otherwise they can cause side effects.

Thank you for your interest in this topic. Please see the discussion in fastify/skeleton#42 (comment) for my reasoning against such a change.

but the test files are a blocker for upgrade since you moved them to the lib folder

[jsumners]

I don't know how that is the case.

OK, the problem was fixed by

• Manually require and export all util scripts #467

Problem:

• Test files included in release tarball and module.exports based on content of directory are messing with esbuild bundler #466
