junit-quickcheck VS copilot.vim

For anyone interested, there's also https://github.com/pholser/junit-quickcheck . Haven't used it myself but looks like an interesting library to explore. It's based on QuickCheck as well AFAIK.

Thank you for the insightful reply. I did struggle to convert the original algorithm I wrote (with while loops / continue / break) to a more functional style using unfold, and also faced an issue with the type signatures when I tried to break down the contents of Stream.unfoldRight to multiple functions, which is reflected to the messy state you mentioned. Regarding property based testing, I used junit-quickcheck and the "symmetry" property check was one I meant to write but wasn't quite sure how to create a generator for it. I created an issue to track my attempt to incorporate your suggestions in case you are interested in following this. Thanks again!

A quick Google search shows that java has a library for this (here) but I've never used it in java so can't attest to it.

QuickcCheck-type tools (generators for tests that know about the edge cases of a domain - e. g. for the domain of numbers considering things like 0, the infinities, various almost-and-just-over powers of two, NaN and mantissas for floats, etc.):

* QuickCheck: https://hackage.haskell.org/package/QuickCheck

* Hypothesis: https://hypothesis.readthedocs.io/en/latest/

* JUnit QuickCheck: https://github.com/pholser/junit-quickcheck

Fuzz testing tools (tools which mutate the inputs to a program in order to find interesting / failing states in that program). Generally paired with code coverage:

* American Fuzzy Lop (AFL): https://github.com/google/AFL

* JQF: https://github.com/rohanpadhye/JQF

Mutation / Fault based test tools (review your existing unit coverage and try to introduce changes to your _production_ code that none of your tests catch)

* PITest: https://pitest.org/

If you want an easy way to have better mutation coverage, check out property based testing. Eg junit-quickcheck for Java.

I use copilot in neovim[1]. It was remarkably simple to get installed. Highly recommend

[1]: https://github.com/github/copilot.vim

I use Plug 'tpope/vim-markdown' and markdown fenced codeblocks fairly extensively, and recently installed Copilot.vim.

Anyways. Yes, neovim has AI integration like copilot ( https://github.com/github/copilot.vim ) and chatgpt ( https://github.com/jackMort/ChatGPT.nvim )

I do think VSCode is a great tool and I recommend it frequently to people, but I still want to set the record straight here. Yes, vim is obviously limited in the sense that as a CLI app it doesn't draw it's own PDF or HTML windows, that's fair. But it can remote control your favorite PDF viewer or browser for roughly the same functionality. I'm currently writing my thesis using vimtex and it's quite smooth. And all the other stuff you mention is implemented quite competently by various plugins like vim-fugitive, coc.nvim, vimspector and copilot.vim.
