Examples with BucketBoundaries io.opencensus.stats.BucketBoundaries used on opensource projects

Example 1 with BucketBoundaries

use of io.opencensus.stats.BucketBoundaries in project instrumentation-java by census-instrumentation.

the class MutableAggregationTest method testCreateEmpty.

@Test
public void testCreateEmpty() {
    assertThat(MutableSumDouble.create().getSum()).isWithin(TOLERANCE).of(0);
    assertThat(MutableSumLong.create().getSum()).isWithin(TOLERANCE).of(0);
    assertThat(MutableCount.create().getCount()).isEqualTo(0);
    assertThat(MutableMean.create().getMean()).isWithin(TOLERANCE).of(0);
    assertThat(MutableLastValueDouble.create().getLastValue()).isNaN();
    assertThat(MutableLastValueLong.create().getLastValue()).isNaN();
    BucketBoundaries bucketBoundaries = BucketBoundaries.create(Arrays.asList(0.1, 2.2, 33.3));
    MutableDistribution mutableDistribution = MutableDistribution.create(bucketBoundaries);
    assertThat(mutableDistribution.getMean()).isWithin(TOLERANCE).of(0);
    assertThat(mutableDistribution.getCount()).isEqualTo(0);
    assertThat(mutableDistribution.getSumOfSquaredDeviations()).isWithin(TOLERANCE).of(0);
    assertThat(mutableDistribution.getBucketCounts()).isEqualTo(new long[4]);
    assertThat(mutableDistribution.getExemplars()).isEqualTo(new Exemplar[4]);
    MutableDistribution mutableDistributionNoHistogram = MutableDistribution.create(BUCKET_BOUNDARIES_EMPTY);
    assertThat(mutableDistributionNoHistogram.getExemplars()).isNull();
}
