The core DataHandling tests are not affected.
But if you add
$this->assertTrue(FALSE);
to
TYPO3\CMS\Core\Tests\Functional\Category\Collection\CategoryCollectionTest::checkIfFromArrayMethodSetCorrectProperties()
you get following error:
1) TYPO3\CMS\Core\Tests\Functional\Category\Collection\CategoryCollectionTest::checkIfFromArrayMethodSetCorrectProperties
