    Map<MetricName, ? extends Metric> metrics = streamsMetrics.metrics();
    // 6 metrics plus a common metric that keeps track of total registered metrics in Metrics() constructor
    assertEquals(metrics.size(), 7);
    streamsMetrics.removeSensor(sensor1);
    metrics = streamsMetrics.metrics();
    assertEquals(metrics.size(), 1);
