// Verify that SVGImage related feature counters get recorded in a separate
// histogram.

useCounter.hasRecordedMeasurement(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(
kSVGCSSHistogramName,
UseCounter::mapCSSPropertyIdToCSSSampleIdForHistogram(CSSPropertyFont),
1);
// After a page load, the histograms will be updated
useCounter.didCommitLoad();
histogramTester.expectBucketCount(kSVGFeaturesHistogramName,

histogramTester.expectTotalCount(kSVGFeaturesHistogramName, 2);
