Support for pre-configured external coverage packages

[wellwelwel]

Support for the --coverage flag, that will require one of the following coverage optional dependencies:

• c8
  • @pokujs/c8
• Istanbul
  • @pokujs/istanbul
• monocart-coverage-reports
  • @pokujs/monocart
• one-double-zero
  • @pokujs/one-double-zero
• "Shared" coverage support across Node.js, Deno, and Bun

---

Usage Ideas

• If the user doesn't use a configuration, Poku should use a default configuration for each one.

@wellwelwel The intention here is to use only one of the 3 libs options for the project (since even c8 is already installed as a dependency) or leave optional so that the user can choose between any of these 3 ?

@DevJoaoLopes, in both v2 and v3, you can choose any package you like and that will never change. This feature's idea is to create pre-configurations for the packages mentioned, but you could choose either one of them or a completely different one 🙋🏻‍♂️

Understood, very cool 🚀
I want to support this development, thank you for your attention @wellwelwel

[DevJoaoLopes]

@wellwelwel Sorry for the delay in getting back to the topic, you know how hard it is to find time 😢

I started to outline the development (there's still a lot to do), and I left everything documented in the #996 .

Just to add my two cents, it would be really beneficial to have an easy way to collect test coverage across Node.js, Bun and Deno. (Would be beneficial for poku as well, or?)

---

Obviously, the native V8 coverage tools will not work on Bun. (Not sure if Deno supports these either.) But that does not mean they should be excluded or so. I think, V8 coverage combined with monocart tooling is the best thing available at the moment.

By the way, there is one more new V8 coverage tool: One Double Zero.

[wellwelwel]

Would be beneficial for poku as well, or?

Yes, definitely! Poku itself lacks coverage reports in these runtimes.

By suggesting an exclusive package for each coverage tool in #996 (e.g., @pokujs/c8), the idea is to keep scope for a possible package of its own, possibly working independently of the poku test runner.

Thanks for the tip. I'll try it out 🙋🏻‍♂️
