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.

Ask HN: Is writing a math proof like programming without ever running your code?
Quickcheck is a Haskell testing library which allows the programmer to write propositions about how a function should behave, and the library will try to find cases which falsify the proposition.
If my understanding is correct, it can't "prove" any properties, only disprove them.
For concretely proving properties of a program, you would need something like Idris's dependent type system, where you can prove that a function always returns a sorted list, for example.

A CRUD journey in Haskell, part I, introduction
Testing is a good engineering practice agnostic to technology or tooling. Haskell is no different and the community created a great tool for Unit testing called HUnit, inspired by the Java JUnit.
