In which I embark to find bugs in my statistex library with property based testing expecting to find nothing because of loose conditions and existing tests… only to find 2 bugs.
I really like the sentiment of the blogpost. If property tests find no issues - great - but more likely they find ones you would’ve never though about or you though would already work.

In @ferd’s book there is a cool example of sending birthday emails where you expect everyone to get it on their birthday… cue 29th of February who should still get one but not “on their birthday”.
And I am still waiting for stateful testing in the stream_data. I have created something similar (stream_state), but it is very rough at the edges and I still have problems with reductions

Hey all,
I have written a blog post about simple techniques that I often use to refactor Phoenix controllers.
There is a number of Elixir-related articles on our blog so be sure to check out the others too.
Because it’s come up a few times on the Elixir slack I figured I should write down a short post on a simple pattern (or two, I guess) for how to handle health checks in a convenient way while avoiding spamming logs.
