### Question:
PlaceDescriptionInfo { public PlaceDescriptionInfo zoomLevel(final Integer zoomLevel) { this.zoomLevel = zoomLevel; return this; }  Integer getZoomLevel(); void setZoomLevel(final Integer zoomLevel); PlaceDescriptionInfo zoomLevel(final Integer zoomLevel); String getRelatedType(); void setRelatedType(final String relatedType); PlaceDescriptionInfo type(final String type); String getRelatedSubType(); void setRelatedSubType(final String relatedSubType); PlaceDescriptionInfo subType(final String subType);  }### Answer:
@Test public void testZoomLevel() { final Integer zoomLevel = 7; PlaceDescriptionInfo result = new PlaceDescriptionInfo(); result.setZoomLevel(zoomLevel); assertEquals(result.getZoomLevel(), zoomLevel); result = new PlaceDescriptionInfo().zoomLevel(zoomLevel); assertEquals(result.getZoomLevel(), zoomLevel); }
