| 1 | """Tests for ``muse rev-list`` — raw commit ID stream with filters. |
| 2 | |
| 3 | Coverage tiers: |
| 4 | - Unit: _walk_from, _parse_range, _parse_date, filter predicates |
| 5 | - Integration: --count, --max-count, --first-parent, --no-merges, --merges, |
| 6 | --author, --after, --before, --touches, --reverse, --json, |
| 7 | A..B range syntax |
| 8 | - End-to-end: full CLI invocation via CliRunner |
| 9 | - Security: ref injection, --touches path traversal, --author regex injection |
| 10 | - Stress: 500-commit chain with --count (flat memory), --touches on large repo |
