Types defined in system_ext/public or product/public can be referenced by vendor side so it is important to make sure functionality is not broken across version bumps. So we are adding the treble sepolicy test cases for system_ext and product sepolicy. Bug: 173571515 Change-Id: Ia45979497029f83b1ae6712d2d26ffab263a7f91
