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.

How programmers make sure that their software is correct
> There are generally two main categories of tests. There are unit tests [and] Integration tests
Later on there is a mention of fuzzing. However, there is something better called property tests. Where the on failure there is automatic "shrinking" of input complexity to find a minimally failing test scenario.
For Erlang and Elixir I recommend https://propertesting.com/ book and the PropEr test framework https://github.com/proper-testing/proper.
As an example, here is the use of an advanced feature called targeted property based testing: https://proper-testing.github.io/tutorials/PropEr_testing_wi... used to test a labyrinth.

Beyond OpenAPI
What this misses is the curl response format.
Long time ago at Klarna we used this tool: https://github.com/for-GET/katt Here's an example: https://github.com/for-GET/katt/blob/master/doc/example-http...
- KATT (Klarna API Testing Tool) Is an HTTP-Based API Testing Tool for Erlang
-
Hurl, run and test HTTP requests with plain text
https://github.com/for-GET/katt is the same concept, but following the pattern matching philosophy. Written in Erlang, available as a CLI tool as well but needs the erlang runtime installed.
Code example: https://github.com/for-GET/katt/blob/master/doc/example-http...
Disclaimer: I'm one of the authors, thus biased, but the reason I'm mentioning katt is that the low barrier of entry for captures and asserts makes it a nice requirement tool for non-techs to write complex API scenarios.
