I just finished my first six weeks working with Clojure and so far I'm pretty happy with the language. I'm developing my personal blog with leiningen and PostgreSQL. I already can publish new content, upload files and I have sessions, cookies and roles, anyway I think at this point I have enough code to start to worry about the testing section, but I'm kind of stuck since looks like a lot of things are happening in the clojure's testing and spec side.

So I have this function:

(defn download "GET /admin/uploads/download/:id" [params] (let [id (-> params :id) upload (model-upload/get-upload id) filename (:filename upload) body (clojure.java.io/file (str "public/uploads/" filename))] {:status 200 :body body :headers {"Content-Type" "application/pdf" "Content-Length" (str (.length body)) "Cache-Control" "no-cache" "Content-Disposition" (str "attachment; filename=" filename)}}))

The function takes a map as argument and delivers a final map to be sent and processed by compojure. I come from a Rails world so the way to test this function in Rails would be to create a FactoryGirl class, create a Rspec model file with the classic:

expect(first_map).to eq(map_returned_by_function)

in it comparing what is expected, and then to run the rspec from the command line to get the green or red line.

Since yesterday I'm trying to replicate that process with Clojure using this doc:

https://www.codesai.com/2018/03/kata-generating-bingo-cards

but I think there is not yet a "standard" way to do a test including the DB (CRUD) part in Clojure. I don't even know where to put the spec files. I see Clojure libraries similar to FactoryGirl but I don't know if I should create my own data structures with spec so I'm not sure where to start, there are clojure.test.check.generators and spec generators but I don't know if they are different or if I should use only spec but not clojure.test.check. Can I run a test from the command line and not inside the REPL?

I mean: is there a document or tutorial about how to test a set of CRUD functions? I think I just need the initial HOWTO and then I could take it from there and I'll write a tutorial to newbies like me.

It looks like Midje is what I'm looking for:
