### Question:
BigIntegerRangeOperations extends RangeOperations<BigInteger> { @Override public BigInteger getValue(String valueString) { return new BigInteger(valueString); }  @Override BigInteger getValue(String valueString); @Override BigInteger getMinValue(); @Override BigInteger getMaxValue(); @Override BigInteger add(BigInteger value, int step); @Override BigInteger subtract(BigInteger value, int step);  }### Answer:
@Test public void testGetValue() { BigInteger actual = bigIntegerRangeOperations.getValue("12"); BigInteger expected = new BigInteger("12"); assertEquals(expected, actual); }
