Types

type TestExporter

type TestExporter struct {
	// contains filtered or unexported fields
}

TestExporter keeps exported metric data in memory to aid in testing the instrumentation.

Metrics can be retrieved with `GetPoint()`. In order to deterministically retrieve the most recent values, you must first invoke `ReadAndExport()`.

func NewTestExporter

func NewTestExporter(metricReader *metricexport.Reader) *TestExporter

NewTestExporter returns a new exporter.

func (*TestExporter) ExportMetrics

func (e *TestExporter) ExportMetrics(ctx context.Context, data []*metricdata.Metric) error

ExportMetrics records the view data.

func (*TestExporter) GetPoint

func (e *TestExporter) GetPoint(metricName string, labels map[string]string) (metricdata.Point, bool)

GetPoint returns the latest point for the time series identified by the given labels.

func (*TestExporter) ReadAndExport

func (e *TestExporter) ReadAndExport()

ReadAndExport reads the current values for all metrics and makes them available to this exporter.

func (*TestExporter) String

func (e *TestExporter) String() string
