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.

AocKt: Test-driven Advent of Code in Kotlin
As you might know, Advent of Code will begin this Friday! If, like me, you want to have a go at solving the puzzles in Kotlin, I would like to share with you a little library I've developed to reduce boilerplate and solve the puzzles in a test-driven approach. It is based on Kotest, a modern and Kotlin-first test framework.

Best practices for Unit Testing Android Apps with Mockk, Kotest and others
As a matter of fact, in the previous examples, we have shifted a bit away from the TDD standards in the meaning that we test not only the operability of our code, but rather check if the code runs according to certain specifications (Given/When/Then). These specifications are our tests, and the syntactic sugar in the form of the possibility to give clear names to the tests using DisplayName and the grouping of the tests by a set of similar attributes helps us clearly formulate these specifications. There is an entire family of frameworks in different languages that allow us to create such specifications: for Java it is Spock, for Ruby—RSpec, and for Kotlin—Spek and Kotest frameworks. Below, I will go into more detail about them.
- Why do Kotlin tests (for Gradle projects) have to be inside classes?

Kotlin Mutation Tests
I've tried so many times. SO MANY. I love the idea of mutation testing. Even chatGPT couldn't help me. It just made up fake mutation testing frameworks to try. To me, pitest is dead. kotest is not mutation testing, but it's property testing is the next best thing I have found to revolutionize your unit tests.

How to improve third-party libraries with Kotlin extensions
The extensions are not particularly useful in this scenario because the described functionality can be incorporated into the Host class. On the other hand, they flourish in test frameworks like Kotest and enable the rapid development of useful add-ons like custom matchers. Extending third-party libraries with utility functions is another prevalent use case. In the next sections, we'll zero in on this specific aspect.
- Are there any plans to make a better build system for Kotlin than Gradle?

Testing with fakes different states?
We're using Kotest for our unit tests and are quite happy with it.

Why does Rusts testing tools seem so much less polished compared to its other tooling?
Testing tools on the JVM stopped using reflection about twenty years ago, they all use annotations these days (e.g. https://testng.org, https://junit.org). Rust has annotations too, obviously.

Reassessing TestNG vs. Junit
Recently though we've run across a few issues with the asserts in TestNG. In 7.3.0, some changes broke assertSame/assertNotSame that also broke some of our tests. This was partially fixed in 7.4.0, but some overloads of assertEquals were still broken. This is fixed, but I don't think the fix has been delivered in a release yet. Further investigation revealed that at least one overload of assertNotEquals has been broken, apparently since 6.9.5 or even earlier.
