Hello everyone! I am investigating Clojure and, more specifically, Luminus <http://www.luminusweb.net/>, for a new service my organization will be building soon. My team and I are really excited by the prospect of trying out something new.
There is a lot that I like about Luminus' design, but I have some concerns about its data-layer is implemented. To be clear, what I mean by "data layer" is the code that deals with querying a SQL database. As I understand it, Luminus uses HugSQL <http://www.hugsql.org/> and Mount <https://github.com/tolitius/mount> to dynamically construct a set of functions at run time and injects them into a namespace that the rest of the application code can then call to perform DB operations. This is very interesting, but I worry that this tightly couples my application code with the data code. For example, what if I want to mock these functions in my unit tests so that my tests don't need to depend on a database connection, or so that I can mock various DB error scenarios to test that my application code handles them appropriately? Coming from a Java background, I would normally place data layer code behind an interface and then at run time pass an implementation of that interface to my application code. This allows me a lot of freedom during unit testing. What would an equivalent design pattern be in Luminus?
