### Question:
Region { public boolean coveredBy(Region other) { return other.getMinPosition() <= this.getMinPosition() && other.getMaxPosition() >= this.getMaxPosition(); } Region(T data); abstract int getStart(); abstract int getEnd(); int getMinPosition(); int getMaxPosition(); T getData(); boolean sameRegion(Region other); boolean overlap(int position); boolean overlap(int position, boolean insertionAware); boolean overlap(Region other); boolean overlap(Region other, boolean insertionAware); boolean coveredBy(Region other); int getLength(); int getCoveredPositions();  }### Answer:
@Test public void coverRegion() throws Exception { Region a = new RegionImpl("x", 100, 200); assertFalse(new RegionImpl("x", 99, 201).coveredBy(a)); assertFalse(new RegionImpl("x", 99, 200).coveredBy(a)); assertFalse(new RegionImpl("x", 100, 201).coveredBy(a)); assertTrue(new RegionImpl("x", 100, 200).coveredBy(a)); assertTrue(new RegionImpl("x", 101, 199).coveredBy(a)); assertFalse(a.coveredBy(new RegionImpl("x", 101, 199))); }
