Testing and Documentation for Reliability

This section turns Testing and Documentation for Reliability into concrete design checkpoints for Java engineers moving toward idiomatic Clojure. Treat the child pages as refactoring lenses: keep the useful design intent, then choose the smallest Clojure mechanism that makes the boundary explicit.

Work through these pages in order when refactoring an existing Java design. For new Clojure code, start with the simplest data flow that passes tests; add abstraction only when call sites repeat the same boundary.
