2. 10 core/modules/file/tests/src/Functional/FileFieldRevisionTest.php \Drupal\Tests\file\Functional\FileFieldRevisionTest::testRevisions()

Tests creating multiple revisions of a node and managing attached files.

Expected behaviors:

• Adding a new revision will make another entry in the field table, but the original file will not be duplicated.
• Deleting a revision should not delete the original file if the file is in use by another revision.
• When the last revision that uses a file is deleted, the original file should be deleted also.
