It probably depends more on where they are coming from. Mox has more overheads for sure than options in Ruby or Javascript. Its more like mocking in Java or C++; where you declare an interface(behaviour), program against that, and then use dependency injection to load the mock or real code at the right time. I'd been working with Elixir for several years when I first tried using Mox and it still took awhile to get my head around it and figure out how to integrate it into our project. I would not be surprised to hear that newer teams really struggle with it. |

I completely agree. Not having an expert Elixirist able to help me: It took me a full six months of fooling around with Mox (and a cryptic feature announcement in the 1.8 release) to really dig into and grok it. At this stage in my elixir experience, I have even PR'd a feature that's been integrated into Mox, so it's not completely incomprhensible, it's a super-well-written library.
Honestly, It's a totally (alien/from-the-future)-technology (in both the good and bad senses) library. The bad senses could be almost trivially fixed with an in-depth, free, online video masterclass or, hell, even a conference lecture on it, and blog posts. More people that really know how it works should blog about how amazing Mox is. Unfortunately, I suspect that the people who are using Mox to its fullest extent are too busy pushing code to prod, ha.
