### Question:
AlleleRegionStoreToHBaseAppendConverter { public void setRegionSize(int regionSize) { this.regionSize = regionSize; } AlleleRegionStoreToHBaseAppendConverter(byte[] columnFamily, int studyId); void setRegionSize(int regionSize); byte[] toBytes(MessageLite msg); byte[] getColumnFamily(); Collection<Append> convert(String chromosome, AlleleRegionStore store); int getRegionSize(); Collection<Append> convert(Region targetRegion, String chromosome, AlleleRegionStore store);  }### Answer:
@Test public void convertRefAndNoCallPos() throws Exception { from.setRegionSize(2); to.setRegionSize(2); testRegionTypePos(5, 22, AlleleInfo.getReferenceAllele()); testRegionTypePos(10, 20, AlleleInfo.getReferenceAllele()); testRegionTypePos(12, 17, AlleleInfo.getReferenceAllele()); testRegionTypePos(5, 22, AlleleInfo.getNoCallAllele()); testRegionTypePos(10, 20, AlleleInfo.getNoCallAllele()); testRegionTypePos(12, 17, AlleleInfo.getNoCallAllele()); testRegionTypePos(10, 10, AlleleInfo.getReferenceAllele()); testRegionTypePos(10, 10, AlleleInfo.getNoCallAllele()); }
