The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

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

Please recommend a good API Mocking tool
I made a library for this: https://github.com/kevin1024/vcrpy

3 Ways to Unit Test REST APIs in Python
Now it’s finally the time to discuss our last option. I have only found about it quite recently, frankly. I’ve been using mocks for a long time and always had some problem with them. VCR.py is a library that simplifies a lot the tests that make HTTP requests.

Two Methods for Testing HTTPS API Calls with Python and pytest and also Communicating with the In-laws
Unfortunately, VCR.py only supports a certain number of HTTP client libraries. Thankfully, some very popular implementations are included: the Python built-in urllib and http.client, as well as requests, urllib3, and aiohttp. And, while it may not be listed in the docs at the time of this writing, the changelog notes that HTTPX is also supported. Sadly, pycurl is not supported.

Magic numbers for Verify?
I don't normally work in Python, so I'm not used to writing mocks. You should be able to mock the client, but if that is too much you might look into something like VCR.py which records underlying HTTP interactions and then plays them back in further tests. (Make sure to redact any API keys from the cassettes though.)
