NewsTest::testItemPublished
Check if only the items with a date in the past AND Live items are there.
Since all items are linked to page1, we only check if page1 has them all indeed. And the children should only be the published or in the past, thus there should be 2 excluded at first run. The future-published-test fails because mock_now doesn't work as expected?!
