你做了什么？

func BenchmarkTest(b *testing.B) {
	for _, name := range []string{"Test"} {
		b.Run(name, func(b *testing.B) {
			for _, subName := range []string{"Subtest"} {
				b.Run(subName, func(bb *testing.B) {
					bb.ReportMetric(100, "sub_test_metric")
				})
			}
			b.ReportMetric(200, "some_metric")
		})
	}
}

你看到了什么发生？

BenchmarkTest
BenchmarkTest/Test

你期望看到什么？

我希望在BenchmarkTest/Test基准测试上报告some_metric。
