Check

(check (my-code) => (needs :tests))

So, yesterday I made a talk (in Portuguese only, unfortunately) about the difficulties of testing Clojure and ClojureScript code. Specifically, I think the most problematic issue is the lack of “custom matcher libraries”, and how the default error messages are kinda bad and don’t help you identify the problems.

Then, on Clojurians’ #announcements Slack channel, I found that clojure.test Expectations library have a new version. So, why not integrate it on my Check library, and maybe continue developing it?

What is check?

Midje is too magic. Clojure.test is too little. Thinking about findind a “middle ground” I’ve started the “check” project, and I’m using it to test my personal projects like Chlorine, Clover, REPL-Tooling and Paprika. The problem is that, while the API is stable, but it still doesn’t do all the things I want.

Two new libraries in Clojure

Last week, I was looking to some old code I wrote in my last job and my spare time. Then, I’ve decided to publish two new libraries for Clojure and ClojureScript.

One is Paprika, available in Clojars at version 0.1.0-SNAPSHOT.

The other is Check, also available in Clojars (but at version 0.0.1-SNAPSHOT).

The reason for the early publishing is to push forward some simple libraries to fix a simple problem that I had while working with Clojure: the absence of abstractions.
