def AtomEditorComponents_SSAO_AddedToEntity():
    """
    Summary:
    Tests the SSAO component can be added to an entity and has the expected functionality.
    Screen Space Ambient Occlusion (SSAO) is a PostFX shadow lighting effect.

    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 SSAO entity with no components.
    2) Add SSAO component to SSAO entity.
    3) UNDO the entity creation and component addition.
    4) REDO the entity creation and component addition.
    5) Verify SSAO component not enabled.
    6) Add PostFX Layer component since it is required by the SSAO component.
    7) Verify SSAO component is enabled.
    8) Enter/Exit game mode.
    9) Test IsHidden.
    10) Test IsVisible.
    11) Delete SSAO entity.
    12) UNDO deletion.
    13) REDO deletion.
    14) Look for errors.
