The thing I miss the most would be spies and stubs ( looking at sinon.js ). Most people end up creating mocks when in reality they don’t need them. It just happens they don’t know about spies for example.
I am a believer that when it comes to designing tests, code and architecture, the simplest solution is usually the best. That’s why in over 2 years of programming I have never used a mock.
In Elixir I find that the solution for everything is just a mock ( mocks should be used carefully ).
A section detailing any of these would clearly up my interest as I have found little information regarding the application of such techniques in the Elixir community.
I have also recently learned about Elixir’s love for property testing which I am new at ( coming from other backgrounds it is the first time I hear about it). A comparison between TDD and PT or how they can be combined together would be interesting to me.
Do note these are my personal opinions based on my personal struggles with Elixir. I have been a seasoned developer in other languages, but coming here I feel there is a lot of adaption needed.
Everyone is entitled to their opinion and as I stated, TDD / BDD is not the holy grail. It may not save you from your demons, but I assure you it has saved me from many ugly demons over the years. It works for me and for the work I do, so I’ll keep defending
