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.

Proptest: property testing in Rust
There's more to Proptest that I wrote in this post (but not much more), please check the documentation. But I hope this practical introduction will help you get started with the library in your projects. Also, check out similar libraries for different languages like the mentioned Hypothesis for Python or jqwik for Java.
- 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.

Is this similar RxJava, the reactive extensions library for https://github.com/ReactiveX/RxJava ? I have made that work in Clojure in production.

How to do threading in Android.
Since you mentioned java, there is RxJava and RxAndroid. Google general recommendation now is to use kotlin coroutines if you're considering writing your app with that.

It hurts
It's very quick though. In terms of the correctness of the syntax, I've never seen an issue while translating a single file or a single function. When I took the entire RxJava code base 5 years ago, right clicked on the source folder and converted to Kotlin, I found lots of problems. File by file I've never seen any issues though, but I also haven't done it much.

You all beat me to MapStruct and Testcontainers. Honorable mention to RxJava, which I use in Desktop apps.

What are the most common used (3rd party) libraries and frameworks used in Android development?
Concurrency: Kotlin coroutines for general use, Rx or Flow for reactive programming (you can technically use Rx for regular concurrency as well, but not really what it's meant for)
What are some alternatives?
When comparing jqwik and RxJava you can also consider the following projects:
Deep Dive - Fluent assertions library for Java
Mutiny - An Intuitive Event-Driven Reactive Programming Library for Java
junit-quickcheck - Property-based testing, JUnit-style
EventBus - Event bus for Android and Java that simplifies communication between Activities, Fragments, Threads, Services, etc. Less code, better quality.
xray-junit-extensions - Enhanced JUnit 5 integration with Xray Test Management for Jira
RxAndroid - RxJava bindings for Android
