This is feature flagged and will not activate until Bun 1.3 - Makes `test.only()` throw an error in CI - Unless `--update-snapshots` is passed: - Makes `expect.toMatchSnapshot()` throw an error instead of adding a new snapshot in CI - Makes `expect.toMatchInlineSnapshot()` throw an error instead of filling in the snapshot value in CI --------- Co-authored-by: Claude Bot <claude-bot@bun.sh> Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
