That said, it’s common to call some functions from another context while being into one, how or when to do this depends by what you’re doing, hence your domain. You ca…

I believe that in many cases, as long as you are able to draw out your dependencies as a directed acyclic graph (in other words: there are no cycles, no contexts that both depend on each-other), then you are usually fine.

I think my main issue is seeing how the chain of the dependencies can grow big and make test really weird sometimes. In this same example, say I created a check to verify that a user is always present in a blog post, but then user itself has its own associations it depends on. There already would h…

[image] Qqwy: I believe that in many cases, as long as you are able to draw out your dependencies as a directed acyclic graph (in other words: there are no cycles, no contexts that both depend on each-other), then you are usually fine. Very much this. Your context are unlikely all on the same…
