### Question:
IntegerRangeConstraintEditor extends AbstractColumnConstraintEditor<T> { @Override public void reset() { T newMinValue = converter.fromLong(0); T newMaxValue = converter.fromLong(0); setValue(getConstraint().copy(newMinValue, newMaxValue)); } IntegerRangeConstraintEditor(ColumnConstraint<T> constraint,
			LongConverter<T> converter); @Override void reset(); @Override String getErrorMessage();  }### Answer:
@Test public void testReset() { setLowerValue(10); setUpperValue(20); runSwing(() -> editor.reset()); waitForSwing(); assertEquals("0", lowerTextField.getText()); assertEquals("0", upperTextField.getText()); }
