"""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.
|
||
|
||
Marker: ``ANM`` — see ``pytest.ini``.
