def AtomEditorComponents_EntityReference_AddedToEntity():

    Summary:
    Tests the Entity Reference component can be added to an entity and has the expected functionality.

    Test setup:
    - Wait for Editor idle loop.
    - Open the "Base" level.

    Expected Behavior:
    The component can be added, used in game mode, hidden/shown, deleted, and has accurate required components.
    Creation and deletion undo/redo should also work.

    Test Steps:
    1) Create an Entity Reference entity with no components.
    2) Add Entity Reference component to Entity Reference entity.
    3) UNDO the entity creation and component addition.
    4) REDO the entity creation and component addition.
    5) 'EntityIdReferences' is a container property
    6) Append item to 'EntityIdReferences'
    7) Add item to 'EntityIdReferences'
    8) Update item in 'EntityIdReferences'
    9) Remove item from 'EntityIdReferences'
    10) Reset the container property then put one entity reference back for further tests
    11) Remove component
    12) UNDO component remove
    13) Enter/Exit game mode.
    14) Test IsHidden.
    15) Test IsVisible.
    16) Delete Entity Reference entity.
    17) UNDO deletion.
    18) REDO deletion.
    19) Look for errors.
