pythonnative.testing renders components without a device or simulator. [render][pythonnative.testing.render] mounts an element into an in-memory [FakeBackend][pythonnative.testing.FakeBackend] and returns a [RenderResult][pythonnative.testing.RenderResult] with Testing Library-style queries and event helpers; [render_hook][pythonnative.testing.render_hook] does the same for a bare hook. [within][pythonnative.testing.within] scopes the queries to one subtree, [wait_for][pythonnative.testing.wait_for] polls a predicate while draining the framework loop, and [fake_clock][pythonnative.testing.fake_clock] puts asyncio timers on virtual time.

Every query comes in four flavors: get_by_* (exactly one match or LookupError), query_by_* (the match or None), get_all_by_* (every match), and find_by_* (get_by_* wrapped in wait_for). RenderResult and the scope returned by within share this class.

Installing pythonnative registers this plugin under the pytest11 entry point, so every pytest session gets the runtime-reset fixture and pn_clock without a conftest.py. Disable it with -p no:pythonnative.
