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.
Java Faker
- Built a library to help generate test pojos with relevant but random data. I’d love some feedback.

Datafaker: An Alternative to Using Production Data
I've been using https://github.com/DiUS/java-faker which seems to be much more popular. How is this one different?

Datafaker, an alternative to using Production Data
This has another bottleneck, each time you request something, it ends up with a IO call to open a file, as all fake data is stored in a file: https://github.com/datafaker-net/datafaker/blob/master/src/main/resources/en/dragon_ball.yml I recently filed a bug to javafaker that in some cases file descriptor was never closed, resulting in even worse performance and memory leaks, killing our service after millions of method calls.

Reasons to avoid RandomStringUtils for test data generation
[]JavaFaker](https://github.com/DiUS/java-faker) is an open-source library based on Faker to generate fake data.

Test Data Factory: Why and How to Use
For that I will introduce you JavaFaker, a is a library that can generate fake random data every time it’s called. For example: if you generate a name all the names generated will be different.

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.

Instancio 2.2.0 released
Instancio is a Java library that aims to eliminate (or at least reduce) manual data setup in unit tests. In a nutshell, you specify a class, and it returns a fully-populated instance. Github's README provides a quick overview: https://github.com/instancio/instancio/
I've been experimenting a little and will be adding support for method references in the next release. Here's issue link if you want to follow.

Java: Automating data setup in unit tests
Properly handling seeds and having reproducible objects was one of the main goals, so it should work as you'd expect. I'd suggest giving it a try and if you run into any issues, just post it on Github discussions.
