Universal packages (Such as testing)

[trymeouteh]

Please make bun:test a universal testing package and other new packages as universal packages for all JS runtimes.

This can be done by releasing bun:test as a npm package that can be used in NodeJS and perhaps Deno. Or by allowing you to import it as runtime:test by making runtime:___ packages a universal standard for all JS runtimes, and other JS runtimes can support runtime:___ packages if they so wish.

For testing, I been using Vitest only because it is not apart of any JS runtime, but Bun comes with many build in things such as bun:test a feature rich test runner package.

Unfortunately because of Bun and Deno coming into the JS runtime scene it has cause a fragmentation of JS tools. We have Vitest, Jest, node:test, deno.test, bun:test for testing alone. Bun test is currently only for Bun, deno.test is currently only for deno, Vitest works with multiple runtimes but needs to be installed separately.

Perhaps a browser testing tool can be included into bun:test or runtime:test?
