def AtomEditorComponents_DeferredFog_AddedToEntity():
    """
    Summary:
    Tests the Deferred Fog 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 Deferred Fog entity with no components.
    2) Add Deferred Fog component to Deferred Fog entity.
    3) UNDO the entity creation and component addition.
    4) REDO the entity creation and component addition.
    5) Verify Deferred Fog component not enabled.
    6) Add PostFX Layer component since it is required by the Deferred Fog component.
    7) Verify Deferred Fog component is enabled.
    8) Enable the "Enable Deferred Fog" parameter.
    9) Enter/Exit game mode.
    10) Test IsHidden.
    11) Test IsVisible.
    12) Delete Deferred Fog entity.
    13) UNDO deletion.
    14) REDO deletion.
    15) Look for errors.
