### Question:
DataTypeConstraint { public HTMLElement getElement() { return view.getElement(); } @Inject  DataTypeConstraint(final View view,
                              final ManagedInstance<DataTypeConstraintModal> constraintModalManagedInstance); void init(final DataTypeListItem listItem); String getValue(); ConstraintType getConstraintType(); HTMLElement getElement(); void enableEditMode(); void disableEditMode(); void refreshView(); void disable(); void enable();  }### Answer:
@Test public void testGetElement() { final HTMLElement expectedElement = mock(HTMLElement.class); when(view.getElement()).thenReturn(expectedElement); final HTMLElement actualElement = dataTypeConstraint.getElement(); assertEquals(expectedElement, actualElement); }
