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 Fuzzing with Jazzer compared to Symflower
So as we see, there are some caveats when working with Jazzer and custom data types, requiring manual work to supply the fuzzer with the correct test drivers, and being able to understand the generated test values. Symflower on the other hand generated a complete test suite fast and presents easy to understand test cases. However, we are still not done: if you find code that does not work for you or has results that could be done better, please let us know through our public issue tracker.

Any extensions for generating unit tests?
Full disclosure: I work for this company and we're always very happy to get feedback from our users. What did you like? What did you not like? Did something work well or not at all? You can also open issues on our GitHub. In case you're interested in the magic behind the curtain feel free to check out our website.

Better table-driven tests: generating Symflower-style unit tests
Creating unit tests will always involve writing some boiler-plate code. That's where editor extensions come in handy. The Symflower Visual Studio Code extension allows you to generate tests in the above unit test style, and even maintain them. Please drop us a line on our public issue tracker if you are missing a feature, found a bug or just want to tell us how you like the extension and the unit test style.

oss-fuzz: https://github.com/google/oss-fuzz :
> We support the libFuzzer, AFL++, and Honggfuzz fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.
> Currently, OSS-Fuzz supports C/C++, Rust, Go, Python, Java/JVM, and JavaScript code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.

Fuzz Testing Is the Best Thing to Happen to Our Application Tests
I love fuzzing as a technique and use it quite regularly, but running AFL++ on even a single program occupies all threads of a high end AMD server for weeks. I'm running it locally so only paying for the electricity. If it was a cloud instance it would cost a small fortune. I think this is a reason it is not used more widely.
I will note that Google have a programme for doing fuzz testing on open source projects using computer from their cloud: https://google.github.io/oss-fuzz/

Java Fuzzing with Jazzer compared to Symflower
We will explore how Jazzer is used to automatically generate malicious inputs for Java programs, and how it compares to Symflower, which can automatically generate unit tests to uncover bugs and errors in your code. With the help of Jazzer, many bugs - some of them even in the OpenJDK - were found already. Also, as of March 2021, Jazzer is officially part of OSS-Fuzz, Google's cloud fuzzing engine. It should be noted that Jazzer is a pure "bug detection" utility that finds reproducers for errors in user code. Symflower can do the same, but provides additional functionalities to boost developer productivity, like generating high coverage unit tests and providing test templates for the software developer or tester.
