### Question:
GenomicBoundary implements Comparable<GenomicBoundary> { public String getChromosome() { return chromosome; } GenomicBoundary(String chromosome, Integer start, int stop);  GenomicBoundary(String chromosome, Integer start, int stop, V annotation); String getChromosome(); Integer getStart(); int getStop(); @Override int compareTo(GenomicBoundary other); boolean isInBoundarie(int position); boolean isInBoundarie(int position, int margin); boolean isPartOfBoundary(GenomicBoundary other); boolean isOverlaping(GenomicBoundary other); V getAnnotation(); int getLength(boolean isInclusive);  }### Answer:
@Test public void testGetChromosome() { GenomicBoundary instance = new GenomicBoundary("1", 1, 2); String expResult = "1"; String result = instance.getChromosome(); assertEquals(result, expResult); }
