+ * Launch two windows, with different owners. One window (slipperyExitWindow) has Flag::SLIPPERY,
+ * and overlaps the other window, slipperyEnterWindow. The window 'slipperyExitWindow' is on top
+ * of the 'slipperyEnterWindow'.
+ *
+ * Inject touch down into the top window. Upon receipt of the DOWN event, move the window in such
+ * a way so that the touched location is no longer covered by the top window.
+ *
+ * Next, inject a MOVE event. Because the top window already moved earlier, this event is now
+ * positioned over the bottom (slipperyEnterWindow) only. And because the top window had
+ * Flag::SLIPPERY, this will cause the top window to lose the touch event (it will receive
+ * ACTION_CANCEL instead), and the bottom window will receive a newly generated gesture (starting
+ * with ACTION_DOWN).
+ * Thus, the touch has been transferred from the top window into the bottom window, because the top
+ * window moved itself away from the touched location and had Flag::SLIPPERY.
+ *
+ * Even though the top window moved away from the touched location, it is still obscuring the bottom
+ * window. It's just not obscuring it at the touched location. That means, FLAG_WINDOW_IS_PARTIALLY_
+ * OBSCURED should be set for the MotionEvent that reaches the bottom window.
+ *
+ * In this test, we ensure that the event received by the bottom window has
+ * FLAG_WINDOW_IS_PARTIALLY_OBSCURED.
