### Question:
ContinuousMeasurementPresentation extends PresentationModel<T> implements LabeledPresentation { public AbstractValueModel getLabelModel() { return new DefaultLabelModel(getBean()); } ContinuousMeasurementPresentation(T bean); AbstractValueModel getLabelModel(); @Override String toString(); String normConfIntervalString();  }### Answer:
@Test public void testGetLabel() { assertEquals("0.0 \u00B1 0.0 (" + d_pg.getSize() +")", d_pres.getLabelModel().getValue()); }
@Test public void testFireStdDevChanged() { getMeasurement().setMean(25.5); AbstractValueModel lm = d_pres.getLabelModel(); PropertyChangeListener l = JUnitUtil.mockStrictListener( lm, "value", null, "25.5 \u00B1 1.1 (1)"); lm.addPropertyChangeListener(l); getMeasurement().setStdDev(1.1); verify(l); }
@Test public void testFireMeanChanged() { getMeasurement().setMean(25.5); getMeasurement().setStdDev(1.1); AbstractValueModel lm = d_pres.getLabelModel(); PropertyChangeListener l = JUnitUtil.mockStrictListener( lm, "value", null, "27.5 \u00B1 1.1 (1)"); lm.addPropertyChangeListener(l); getMeasurement().setMean(27.5); verify(l); }
