We can enforce a specific order by sorting `dirnames`.\r\n\r\nhttps://github.com/python/cpython/blob/a6f95941a3d686707fb38e0f37758e666f25e180/Lib/test/test_pathlib.py#L2680-L2694\r\n\r\n`test_walk_bottom_up()` suffers similar problems, and also makes unjustified assertions about the order that siblings are visited (which is arbitrary and cannot be influenced by the user, contrary to top-down mode). It can be simplified to ensure that children are yielded before parents.\r\n\r\nhttps://github.com/python/cpython/blob/a6f95941a3d686707fb38e0f37758e666f25e180/Lib/test/test_pathlib.py#L2717-L2735\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-103518\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/barneygale","@type":"Person","name":"barneygale"},"datePublished":"2023-04-13T16:28:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/103517/cpython/issues/103517"}
