### Question:
InverseGridWidgetClipper implements IPathClipper { @Override public boolean isActive() { return isActive; } InverseGridWidgetClipper(final GridWidget outer,
                                    final GridWidget inner); @Override boolean clip(final Context2D context); @Override boolean isActive(); @Override boolean setActive(final boolean isActive);  }### Answer:
@Test public void testIsActive() { clipper.setActive(true); assertThat(clipper.isActive()).isTrue(); clipper.setActive(false); assertThat(clipper.isActive()).isFalse(); }
