Testing with Behavior-Oriented Concurrency (BOC)

This skill describes how to write tests for code that uses the bocpy library for behavior-oriented concurrency. BOC schedules work as behaviors — decorated functions that run once all required cowns (concurrently-owned data) are available. Testing BOC programs requires specific patterns because behaviors execute asynchronously on worker interpreters.

Design guidance: if you find yourself reaching for time.sleep, threading.Event, polling loops, or wait_for_* helpers inside a behavior or in test code that drives one, stop and read thinking-in-boc first. The right answer is almost always to express the dependency through the cown graph, not through a classical synchronization primitive.
