{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Add tests for command-line interface","articleBody":"While working on #130160 and #93096 it was decided that it would be worth paying attention to the problem of lack of tests for command line interface.\n\nList of all cli modules is in the documentation: https://docs.python.org/dev/library/cmdline.html\n\nMany modules are missing command line interface tests, so I suggest using this issue to submit PRs for now only for well-documented interfaces, for example:\n\n- [x] `tokenize` (gh-131274)\n- [x] `platform` (gh-131542)\n- [x] `pickle` (gh-131275)\n- [x] `ast` (gh-133329)\n- [x] `pickletools` (gh-131287)\n- [x] `http.server` (gh-132540)\n- [ ] `profile` (gh-134103)\n- [ ] `cProfile` (gh-134269)\n- [x] `site` (gh-133582)\n\nTODO: Make sure [all documented](https://docs.python.org/dev/library/cmdline.html) have tests for CLI (others are not so important as it has not been decided what to do with them yet)\n\nYou can use PR #127759 for `dis` module or #118132 for `random` module as a reference.\nAnd I also suggest using `subprocess.Popen` to allocate a separate resource since some modules can block a lot of time.\n\n\u003e [!IMPORTANT]\n\u003e For those who want to work on the issue, please:\n\u003e * Select one module for which tests will be improved. It's easier to review and backport.\n\u003e * Open a pull request with the following title: `` gh-131178: Add tests for `MODULE_NAME` command-line interface ``\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-131274\n* gh-131275\n* gh-131287\n* gh-131326\n* gh-132540\n* gh-133329\n* gh-133582\n* gh-134103\n* gh-134224\n* gh-134269\n* gh-134279\n* gh-134287\n* gh-137748\n* gh-137807\n* gh-137816\n* gh-137832\n* gh-137833\n* gh-139934\n* gh-139947\n* gh-139983\n* gh-140199\n* gh-140200\n* gh-143835\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/donbarbos","@type":"Person","name":"donbarbos"},"datePublished":"2025-03-13T09:15:51.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/131178/cpython/issues/131178"}
