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) Remove SSAO component.
    4) UNDO component removal.
    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) Toggle Enable SSAO (default True)
    9) Toggle Enable Blur False (default True)
    10) Set SSAO Strength to high/low values then return to default
    11) Set Sample Radius to high/low values then return to default
    12) Set Blur Strength to high/low values then return to default
    13) Set Blur Edge Threshold to high/low values
    14) Set Blur Sharpness to high/low values then return to default
    15) Toggle Enable Downsample (default True)
    16) Toggle Enabled Override (default True)
    17) Set Strength Override to 0.0 then return to default 1.0
    18) Set SamplingRadius Override to 0.0 then return to default 1.0
    19) Toggle EnableBlur Override (default True)
    20) Set BlurConstFalloff Override to 0.0 then return to default 1.0
    21) Set BlurDepthFalloffStrength Override to 0.0 then return to default 1.0
    22) Set BlurDepthFalloffThreshold Override to 0.0 then return to default 1.0
    23) Toggle EnableDownsample Override (default true)
    24) Enter/Exit game mode.
    25) Test IsHidden.
    26) Test IsVisible.
    27) Delete SSAO entity.
    28) UNDO deletion.
    29) REDO deletion.
    30) Look for errors.
