the class AbstractEthTaskTest method shouldHaveSpecificMetricsLabels.

@Test
public void shouldHaveSpecificMetricsLabels() {
    // seed with a failing value so that a no-op also trips the failure.

        public LabelledMetric<OperationTimer> createLabelledTimer(final MetricCategory category, final String name, final String help, final String... labelNames) {
            return names -> {
                lastLabelNames[0] = names[0];
