Functions

func AssertExpvarNormalHistogram

func AssertExpvarNormalHistogram(t *testing.T, metricName string, mean, stdev int64, quantiles []int)

AssertExpvarNormalHistogram ensures the expvar Histogram referenced by metricName abides a normal distribution.

func AssertPrometheusBucketedHistogram

func AssertPrometheusBucketedHistogram(t *testing.T, metricName string, mean, stdev int64, buckets []float64)

AssertPrometheusBucketedHistogram ensures the Prometheus Histogram referenced by name has observations in the expected quantity and bucket.

func AssertPrometheusNormalSummary

func AssertPrometheusNormalSummary(t *testing.T, metricName string, mean, stdev int64)

AssertPrometheusNormalSummary ensures the Prometheus Summary referenced by name abides a normal distribution.

func PopulateNormalHistogram

func PopulateNormalHistogram(t *testing.T, h metrics.Histogram, seed int64, mean, stdev int64)

PopulateNormalHistogram populates the Histogram with a normal distribution of observations.
