2. 9 core/modules/field/tests/src/Kernel/BulkDeleteTest.php \Drupal\Tests\field\Kernel\BulkDeleteTest::testDeleteField()

Verify that deleting a field leaves the field data items in the database and that the appropriate Field API functions can operate on the deleted data and field definition.

This tests how EntityFieldQuery interacts with field deletion and could be moved to FieldCrudTestCase, but depends on this class's setUp().
