Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Need your feedback on a tool that auto-generates unit tests for java code
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.

Coding Challenge
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!

Does anyone have any advice for writing better Java tests.
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.

GitHub Copilot for JetBrains and Neovim
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/

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

GitHub Copilot for JetBrains and Neovim
So it looks like for neovim there is not yet the option to cycle through suggestions?
Looks like for VSCode the shortcut on Linux is Alt-], see: https://github.com/github/copilot-docs/blob/main/docs/visual...
But for neovim, it doesn't mention anything about it in the docs: https://github.com/github/copilot.vim/blob/release/doc/copil...
And, nothing happens when pressing Alt-].
What are some alternatives?
