"""Migrated from SWE5 ANM Management Integration Test Plan. Source: ``25IMR003_ForSeven_RGB-SWITD_06-ANM Management (Integration Test Plan).xlsm`` Translation strategy -------------------- The workbook references debugger-only firmware variables (``u8AnmMode``, ``strAnmState.bActive``, ``strAnmState.u16TimeUnits``, ``strAnmState.prevR/G/B/I``). These cannot be observed over the LIN bus, so each test is rewritten to exercise the **LIN-observable** behaviour that those variables produce: - ``u8AnmMode`` — observed indirectly via ALMLEDState transitions: Mode 0 reaches LED_ON without passing through ANIMATING; Modes 1/2 with ``AmbLightDuration > 0`` do pass through ANIMATING. - ``strAnmState.bActive`` — equals ``ALMLEDState == LED_ANIMATING``. - ``strAnmState.u16TimeUnits`` — measurable as the duration of the ANIMATING window, in seconds, via :meth:`AlmTester.measure_animating_window`. - ``strAnmState.prevR/G/B/I`` — the *final* RGBI is verified via PWM_wo_Comp; per-tick intermediates are not LIN-observable and are documented as such.
