### Question:
ParallelismQueryParameter extends MessageQueryParameter<Integer> { @Override public Integer convertStringToValue(final String value) { return Integer.valueOf(value); } ParallelismQueryParameter(); @Override Integer convertStringToValue(final String value); @Override String convertValueToString(final Integer value);  }### Answer:
@Test public void testConvertStringToValue() { assertEquals("42", parallelismQueryParameter.convertValueToString(42)); }
@Test public void testConvertValueFromString() { assertEquals(42, (int) parallelismQueryParameter.convertStringToValue("42")); }
