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.

PHP: testing, "Attention please!"
consider adding mutation tests

Who tests the tests? Mutation testing with Infection in PHP
Obviously, we can not generate mutants manually. For that purpose, there are mutation testing utilities. For PHP, we have Infection.

I created a package to encourage developers in my team to write tests. What do you think? Any feedback? Thanks!
If you want to enforce testing automatically probably the best option is to rely on mutation testing, using Infection. That doesn't just check that the tests cover the code, it checks that if the code was different to what it is then the tests would (usually) fail.

Collecting line, branch, and path coverage with PHPUnit
IMO code coverage is a very flawed metric on its own. A high percentage doesn't guarantee that the tests actually test the right things, and it would be much more efficient if mutation testing was used (e.g. Infection). It still uses the generated code coverage reports, but only as a base for its own metrics.
-
Am I writing the right kinds of (unit) tests? See below for an example. Thanks!
For your last edit - you can also add infection which will infect your code with other values, like if you expect a positive number, it will try and inject a negative number - and see what happens - does your code break everything or something. Also it will try to inject false where you might expect a true and many many other things, and yes you will get some weird results from infection, but its a good thing to look at, and atleast check the logs and see why the infection failed at a test.
- I'm looking for "complex" or "advanced" topics that don't get enough coverage

Codewars Kata. It uses 100 random tests for a boolean.
The only one that I've used is infection for PHP.
-
Verify your true code coverage by removing lines of PHP code, see if it affects PHPUnit results
That's practically a light form of mutant testing. Have you checked Infection?
