### Question:
StoredMetric extends AbstractMetric<V> implements SettableMetric<V> { @VisibleForTesting final void set(V value, ImmutableList<String> labelValues) { this.values.put(labelValues, value); } StoredMetric(
      String name,
      String description,
      String valueDisplayName,
      ImmutableSet<LabelDescriptor> labels,
      Class<V> valueClass); @Override final void set(V value, String... labelValues); @Override final ImmutableList<MetricPoint<V>> getTimestampedValues(); @Override final int getCardinality();  }### Answer:
@Test public void testSet_wrongNumberOfLabels_throwsException() { StoredMetric<Boolean> dimensionalMetric = new StoredMetric<>( "/metric", "description", "vdn", ImmutableSet.of( LabelDescriptor.create("label1", "bar"), LabelDescriptor.create("label2", "bar")), Boolean.class); IllegalArgumentException thrown = assertThrows(IllegalArgumentException.class, () -> dimensionalMetric.set(true, "foo")); assertThat(thrown) .hasMessageThat() .contains( "The count of labelValues must be equal to the underlying Metric's count of labels."); }
