DataTypeConstraint { public void enableEditMode() { isEditModeEnabled = true; view.showAnchor(); } @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 testEnableEditMode() { dataTypeConstraint.enableEditMode(); assertTrue(dataTypeConstraint.isEditModeEnabled()); verify(view).showAnchor(); }
