### Question:
OneSidedConvergingDoubleAccumulator extends OneSidedStDevAccumulator<Double> { @Override protected void accumulateValue(Double result) { accumulatedValue += result; } OneSidedConvergingDoubleAccumulator(boolean highIsCritical, double precision, int minValuesAccepted,
            int maxValuesAccepted);   }### Answer:
@Test public void testAccumulateValue() { double sum = 0.0; for (int i = 0; i < 10; i++) { double value = Math.random(); accumulator.accept(value); sum += value; assertEquals(sum, accumulator.getAccumulatedValue()); } }
