Hoi Bas,
Thank you for your answer!
So maybe I am doing it wrong.
Let's take an example. In the wicket examples, in package
org.apache.wicket.examples.repeater, there is the provider:
public class SortableContactDataProvider_my extends
SortableDataProvider_my<Contact, String> implements
IFilterStateLocator<ContactFilter_my>
{
...
protected ContactsDatabase getContactsDB()
{
return DatabaseLocator.getDatabase();
}
@Override
public Iterator<Contact> iterator(long first, long count)
{
List<Contact> contactsFound = getContactsDB().getIndex(getSort());
return filterContacts(contactsFound).
subList((int)first, (int)(first + count)).
iterator();
}
I mocked the iterator method. But you are saying that I should mock the
getContactsDB method?
Thank you.
