Yes, and that their data is fed correctly to the items.

Thanks, we all should learn Scala anyway so feel free to
post in it ;)

Pass in a mock IDataProvider there, and then see that the
accounts that the mock returns get listed on the page.
for (Account account : accountsSuppliedByMockDataProvider) {
assertEquals(account, findItemOf(account).getModelObject());
assertEquals(account.getName(),
findNameLabelOf(account).getModelObjectAsString());
}
Or something like that.
If your repeater initialises lazily, you sometimes have to
call .renderComponent() on it on the test so that its
children get created. But if it already gets its data on
when it's first constructed and "started" by WicketTester, it
should be rendered and the Items should be there.
Best wishes,
