Examples of com.google.caliper.util.ShortDuration

com.google.caliper.util.ShortDuration
Represents a nonnegative duration from 0 to 100 days, with picosecond precision. Contrast with Joda-Time's duration class, which has only millisecond precision but can represent durations of millions of years.

public class RuntimeWorkerTest {
  private static final ShortDuration TIMING_INTERVAL = ShortDuration.of(100, MILLISECONDS);


  @Test public void testCalculateTargetReps_tinyBenchmark() {
    // this is one cycle on a 5GHz machine
    ShortDuration oneCycle = ShortDuration.of(new BigDecimal("2.0e-10"), SECONDS);
    long targetReps = calculateTargetReps(INITIAL_REPS,
        oneCycle.times(INITIAL_REPS).to(NANOSECONDS), TIMING_INTERVAL.to(NANOSECONDS), 0.0);
    long expectedReps = TIMING_INTERVAL.toPicos() / oneCycle.toPicos();
    assertEquals(expectedReps, targetReps);
