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.

Mocking Python datetime In Tests With FreezeGun
FreezeGun is a library that helps with mocking out the datetime.datetime.now function. It is a very useful tool for testing code that uses the datetime library.

Introduction to Flaky Tests by Example
Another way of doing so would be to inject the value directly to the method. Python has a very good library to sandbox the tests when using the built-in datetime objects: freezegun. Once again, and unfortunately for us, the project was using arrow so this was not a possibility.

About time: how to unit test code that depends on time
Freezegun is pretty much unmaintained. You want time-machine https://github.com/adamchainz/time-machine

Running C unit tests with pytest
There are lots of good mocking fixtures available for pytest. I've used this one for clock stuff in the past: https://github.com/adamchainz/time-machine#pytest-plugin
