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.

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.

An Introduction to Mocking Tools for Elixir
If you are used to Mocha for other languages, you can check out Mimic. It lets you define stubs and expectations during tests by keeping track of the stubbed module in an ETS table.

Purity injection in Elixir
By adjusting the mindset to stop thinking about dependencies and start to think about behaviours (functions) we were able to extract the impure parts of the number generator function. Then, by making them injectable we transformed the impure function to the one into which we can inject purity in tests, making it essentially pure and thus much easier to test. We also didn't need any fancy tool like Mox, Mimic or Rewire to define replacement modules for us. The code is hopefully understandable and uses only built-in Elixir idioms, without macros.
