| 1 | """Tests for ``muse range-diff`` — supercharged coverage. |
| 2 | |
| 3 | Coverage tiers |
| 4 | -------------- |
| 5 | - Unit: _parse_range, _resolve_ref (sha256: prefix), _compute_patch_id, |
| 6 | _patch_id_for_commit, _pair_series pairing logic |
| 7 | - Integration: identical series, changed/dropped/added, JSON schema, |
| 8 | text output, creation-factor variants, error cases |
| 9 | - End-to-end: full CLI via CliRunner |
| 10 | - Data integrity: old_count/new_count match pair list; files_changed per commit; |
| 11 | patch_id has sha256: prefix; duration_ms is numeric |
| 12 | - Performance: 50-commit series completes under 2 seconds |
| 13 | - Security: ANSI injection rejected; no control characters in output |
| 14 | - Stress: 50-commit mixed series (equivalent + changed + added) |
| 15 | |
| 16 | Supercharged JSON schema (all ``--json`` outputs) |
