示例1: useCounter

  HistogramTester histogramTester;

  // Verify that SVGImage related feature counters get recorded in a separate
  // histogram.
  EXPECT_FALSE(
      useCounter.hasRecordedMeasurement(UseCounter::SVGSMILAdditiveAnimation));
  useCounter.recordMeasurement(UseCounter::SVGSMILAdditiveAnimation);
  EXPECT_TRUE(
      useCounter.hasRecordedMeasurement(UseCounter::SVGSMILAdditiveAnimation));
  histogramTester.expectUniqueSample(kSVGFeaturesHistogramName,
                                     UseCounter::SVGSMILAdditiveAnimation, 1);

  // And for the CSS counters
  EXPECT_FALSE(useCounter.isCounted(CSSPropertyFont));
  useCounter.count(HTMLStandardMode, CSSPropertyFont);
  EXPECT_TRUE(useCounter.isCounted(CSSPropertyFont));
  histogramTester.expectUniqueSample(

  histogramTester.expectTotalCount(kSVGFeaturesHistogramName, 2);
  histogramTester.expectBucketCount(kSVGCSSHistogramName, 1, 1);
  histogramTester.expectTotalCount(kSVGCSSHistogramName, 2);

  // And the legacy histogram will be updated to include these
  histogramTester.expectBucketCount(kLegacyFeaturesHistogramName,
