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 to ignore a child of a Supervisor not being able to start during tests?
In order to do this you may use mock (which is simple to use), mox (they have pretty compelling arguments why not to mock traditionally), or specifically for http requests, bypass.

8 Common Causes of Flaky Tests in Elixir
Your options are mock ets/persistent_term — after all, we don't need to test that these things do what they say (Erlang does that for us!) — or have the tests run synchronously. Prefer the former! Mox is a great choice for this sort of work.
