data.sub - test values against subcollections

Abstract

(data.sub/sub? sub x) will return true if the expected sub subtree matches the actual x value.

(sub? {:a [1 nil [3]]}
      {:a [1 2   [3 4] :continued] :b "something"})
=> true

The sub description is designed to look similar to the actual x value, and matches recursively, where "uninteresting" parts can be left off or specified as nil - which will match anything.

Humane test output

data.sub can integrate with pjstadig/humane-test-output to report subdiffs on failing (sub?) tests.

To enable this, setup your leiningen profiles.clj or project.clj like:

   {:dependencies [[pjstadig/humane-test-output "0.8.1"]
                   [nl.zeekat/data.sub "0.1.2"]]
    :injections   [(require 'pjstadig.humane-test-output)
                   (pjstadig.humane-test-output/activate!)
                   (require 'nl.zeekat.data.sub.humane-test-output)
                   (nl.zeekat.data.sub.humane-test-output/activate!)]}
