Running tests with lein test means waiting for the JVM startup, and waiting for the project to compile. Prism recompiles and reloads files as you change them, and re-runs their corresponding tests immediately. Inspired by Midje's excellent autotest.


Check out Clojars for the latest version number, then add Prism to ~/.lein/profiles.clj:

 {:plugins [[com.aphyr/prism "0.1.1"]]
  :dependencies [[com.aphyr/prism "0.1.1"]]}}

You could alternatively add Prism to the dev dependencies in a given project–but this lets you use Prism against any project regardless of its project.clj.

Then, just run lein prism in your project directory. It'll do a full test first, then as you write .clj files, it'll re-run the corresponding test namespace. Prism assumes your tests are named foo.core-test.

Why “Prism”?

It may be snooping on everything you write, and checking to make sure it's not dangerous. Or maybe not! Exciting!
