Elm gets one thing amazingly right (which is unusual in most ecosystems) in that it has in its "default" testing tool built in support for property based testing1. This is a huge step forward since it makes property testing something easily reachable for by the average engineer without needing yet another dependency and boilerplate to set it up and so on.
However, there are a number of things we could do to make fuzz testing more effective and in that way make testing more effective.

The one thing it gets amazingly wrong is calling it fuzz testing. Sigh. Fuzz testing is the practice of trying to find inputs that will crash your program or make it behave in unexpected ways. Fuzzers in Elm aren't even trying, for instance float fuzzers don't send in
NaN
or-Infinity
or even-0
. Int fuzzers don't send in fractional numbers maquarading as floats. String fuzzers don't send in snippets that might trigger bugs in elm-parser. ↩

The Elm Architecture is one of the great innovations Elm brought to the software industry. But one of the questions that often comes up is how to scale it up for bigger applications. In this article I want to show various ideas that allow you to enhance the Elm architecture to make developing larger applications easier.
But first, we should discuss the Runtime. Elm, as a programming language is completely pure
This gist illustrates how you would add Google Analytics tracking into your Rails mailers. Add the tracking_interceptor.rb
into your path and enable it for your mailers with:
register_interceptor TrackingInterceptor

Critique may sound negative, but it's not. I think the aproach has great potential, but there is a lot to do. What I'm attempting to do here is to offer a perspective on the current implementation noting some gaps in capabilities as well as some of the strengths of the library in hope that this will be helpful building out the future of graphics programming in Elm.
