def AtomEditorComponents_DirectionalLight_AddedToEntity():

    Summary:
    Tests the Directional Light 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 a Directional Light entity with no components.
    2) Add Directional Light component to Directional Light entity.
    3) UNDO the entity creation and component addition.
    4) REDO the entity creation and component addition.
    5) Enter/Exit game mode.
    6) Test IsHidden.
    7) Test IsVisible.
    8) Add Camera entity.
    9) Add Camera component to Camera entity
    10) Set the Directional Light component property Shadow|Camera to the Camera entity.
    11) Delete Directional Light entity.
    12) UNDO deletion.
    13) REDO deletion.
    14) Look for errors and asserts.
