Example 2 with MeasureDouble

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

the class ViewManagerImplTest method preventRegisteringDifferentMeasureWithSameName.

@Test
public void preventRegisteringDifferentMeasureWithSameName() {
    MeasureDouble measure1 = MeasureDouble.create("measure", "description", "1");
    MeasureLong measure2 = MeasureLong.create("measure", "description", "1");
    View view1 = View.create(VIEW_NAME, VIEW_DESCRIPTION, measure1, DISTRIBUTION, Arrays.asList(KEY), CUMULATIVE);
    View view2 = View.create(VIEW_NAME_2, VIEW_DESCRIPTION, measure2, DISTRIBUTION, Arrays.asList(KEY), CUMULATIVE);
    testFailedToRegisterView(view1, view2, "A different measure with the same name is already registered");
