Testing Made Simple
summary
Practical rules for Clojure(script) testing: focus on narrow units, clear English descriptions, and isolation instead of biting the whole onion. Demonstrates a concrete union-initialization function tested by a merge-state stub with argument capture and call-count assertions so tests stay cheap and specific. Uses Untangled Spec to validate mocked contracts and shows when to use generative testing with a slow trusted implementation (sine example) to check numeric accuracy and edge cases.
