Check that you have a valid GITHUB_TOKEN set in your environment.`\n```\nor alternatively with\n```\nhypothesis.errors.HypothesisWarning: Could not connect to GitHub to get the latest artifact.\n```\nwhen I restrict the access to the internet.\n\n\nI see that running with `\"CI\"` set in the environment fixes the issue as the problematic profile with `GitHubArtifactDatabase` is not registered, but that seems more like a lucky workaround.\n\nI am not sure about the solution - maybe it can check whether `\"GITHUB_TOKEN\"` is also available? Or maybe the warning should be ignored and not cause the tests to fail.\n\nI also think it should honor `-urlfetch` and `-network` options.\n\n\n### CPython versions tested on:\n\n3.13\n\n### Operating systems tested on:\n\nOther\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-132348\n* gh-132367\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/kulikjak","@type":"Person","name":"kulikjak"},"datePublished":"2025-04-09T12:17:48.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/132316/cpython/issues/132316"}
