id3c.tests.test_check_cam_armed
===============================

.. py:module:: id3c.tests.test_check_cam_armed

.. autoapi-nested-parse::

   Tests for ``_check_cam_armed``.

   Mocks the cam via SimpleNamespace.  The function is a plan stub
   (yields ``bps.sleep(...)`` messages), so we exhaust the generator
   manually and assert behaviour.

Module Contents
---------------

.. py:function:: test_armed_state_returns_immediately()

   Acquire on first poll -> generator returns with no sleeps.


.. py:function:: test_error_state_raises_with_status_message()

   Error state on first poll -> RuntimeError with msg.


.. py:function:: test_each_error_state_raises()

   All four error states trigger the raise.


.. py:function:: test_eventual_acquire_after_polls()

   If state goes Initializing -> Initializing -> Acquire, the
   helper yields sleeps and then returns cleanly.


.. py:function:: test_timeout_does_not_raise()

   If state never becomes Acquire or Error within max_wait_s,
   the helper returns without raising (the downstream first-frame
   timeout handles genuinely stuck cams).


.. py:function:: test_error_after_initializing_still_raises()

   A transition Initializing -> Error mid-poll is caught.


.. py:function:: test_status_message_get_failure_is_safe()

   If status_message.get() raises, we still raise with the
   detector_state info.


.. py:function:: test_detector_state_get_failure_is_safe()

   If detector_state.get() raises, the helper does not raise
   spuriously; it just keeps polling until the max_wait_s expires.
