def C15308221_Material_ComponentsInSyncWithLibrary():
    """
    Summary:
    Runs an automated test to verify that the material library is always in sync between the different PhysX components

    Level Description:
    A new material library was created with 1 material, called "Modified":
        dynamic friction: 0.5
        static friction:  0.5
        restitution:      0.25

    There are 4 types of components we want to test for:
        PhysX Ragdoll:
            A ragdoll ("ragdoll") with the "Modified" material applied to all of its colliders. Positioned above the
            terrain.
        PhysX collider:
            A PhysX box collider ("collider") with a the "Modified" material applied. Positioned above the terrain.
        PhysX terrain:
            A PhysX terrain ("terrain"), and a PhysX box collider ("terrain_box"). "terrain_box" is positioned above
            "terrain". A new layer was created with the "Modified" material and painted onto the terrain under
            "terrain_box". "terrain_box" has the default material applied.
        PhysX character controller:
            A character controller ("character_controller"), and a PhysX box collider ("controller_box").
            "controller_box" is positioned above "character_controller" and is assigned the default material.
            "character_controller" is assigned "Modified"

    Expected behavior:
    For every iteration this test measures the bounce height of each entity. The entities save their traveled distances
    each iteration, to verify different behavior between each setup.

    First the test verifies the entities all behave identically, without changing anything. All entities should bounce
    the same height.

    Next, the test modifies the restitution value for 'Modified' (from 0.25 to 0.75). All entities should again bounce
    the same height. Additionally, all entities should bounce higher with the new restitution than they did previously.

    Test Steps:
    1) Open level
    2) Collect basis values without modifying anything
        2.1) Enter game mode
        2.2) Find entities
        2.3) Wait for entities to bounce
        2.4) Exit game mode
    3) Verify all entities behave the same as a baseline
    4) Modify the restitution value of 'modified'
        4.1 - 4.4) <same as 2.1 - 2.4>
    5) Verify the entities all still behave the same
    6) Verify that the material change was propagated correctly
    7) Close editor

    Note:
    - This test file must be called from the Open 3D Engine Editor command terminal
    - Any passed and failed tests are written to the Editor.log file.
            Parsing the file or running a log_monitor are required to observe the test results.
