### Question:
LienzoPanelMediators { public LienzoPanelMediators setMinScale(final double minScale) { selector.setMinScale(minScale); mediators.setMinScale(minScale); return this; } @Inject  LienzoPanelMediators(final LienzoCanvasMediators mediators,
                                final ZoomLevelSelectorPresenter selector); LienzoPanelMediators init(final Supplier<LienzoCanvas> canvas); LienzoPanelMediators setMinScale(final double minScale); LienzoPanelMediators setMaxScale(final double maxScale); LienzoPanelMediators setZoomFactor(final double factor); void enable(); void disable(); @PreDestroy void destroy();  }### Answer:
@Test public void testSetMinScale() { tested.setMinScale(0.4d); verify(selector, times(1)).setMinScale(eq(0.4d)); verify(mediators, times(1)).setMinScale(eq(0.4d)); }
