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.

- Jqwik – Property-Based Testing on the JUnit Platform
- Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
-
Built a library to help generate test pojos with relevant but random data. I’d love some feedback.
See https://jqwik.net
- I just implemented a method that checks if a binary tree is symmetric, and now I want to test it with Junit. Do I need to manually create a bunch of trees, or is there an easier way?

Simple example of property-based testing
Once we knew which property to use it was very straightforward to add a property-based test for it. We used the jqwik library. We like it because it has very good documentation and it is integrated with Junit.
-
must known frameworks/libs/tech, every senior java developer must know(?)
Jqwik - I love property based testing and the way it can make you think differently about some of your code.
-
Mutation testing java projects
Different to mutation testing, but on a semi-relatednpath, I've found property-based testing (e.g. https://jqwik.net/) to be valuable - thinking about the “shape“ of the expected output and getting a bunch of pseudorandom tests is pretty handy, especially for utility functions.
