@Test
public void testGetMetricValue() {
	final Counter backingCounter = new SimpleCounter();
	final DCounter counter = new DCounter(backingCounter, "counter", "localhost", Collections.emptyList(), () -> 0);

	// sane initial state
	assertEquals(0L, counter.getMetricValue());
	counter.ackReport();
	assertEquals(0L, counter.getMetricValue());

	// value is compared against initial state 0
	backingCounter.inc(10);
	assertEquals(10L, counter.getMetricValue());

	// last value was not acked, should still be compared against initial state 0
	backingCounter.inc(10);
	assertEquals(20L, counter.getMetricValue());

	// last value (20) acked, now target of comparison
	counter.ackReport();
	assertEquals(0L, counter.getMetricValue());

	// we now compare against the acked value
	backingCounter.inc(10);
	assertEquals(10L, counter.getMetricValue());

	// properly handle decrements
	backingCounter.dec(10);
	assertEquals(0L, counter.getMetricValue());
