| 1 | """Supercharge tests for ``muse format-patch``. |
| 2 | |
| 3 | TDD — sections labelled [RED] contain tests that fail until the feature lands. |
| 4 | Sections labelled [GREEN] fill gaps against existing behavior. |
| 5 | |
| 6 | New features under test |
| 7 | ----------------------- |
| 8 | - ``--agent-id <id>`` [RED] embed agent provenance in the patch record |
| 9 | - ``--model-id <id>`` [RED] embed model provenance in the patch record |
| 10 | - ``--intent <text>`` [RED] embed an intent description in the patch record |
| 11 | - ``--no-blobs`` [RED] omit base64 blob content from the patch file |
| 12 | - Rename detection [RED] same-oid delete+insert → rename op in files_renamed |
| 13 | |
| 14 | Gap-fill coverage |
| 15 | ----------------- |
| 16 | - Register-flag parser shape |
| 17 | - Unit tests for _sem_ver_bump, _breaking_changes, _make_patch_filename, _action_label |
| 18 | - Blob content verification (decoded bytes match source) |
| 19 | - from/to manifest delta correctness |
| 20 | - Initial-commit sentinel (from_snapshot_id = sha256:000…, from_commit_id = "") |
| 21 | - Required-objects sorted + sha256: prefix |
| 22 | - ops count === files_added + files_modified + files_deleted |
| 23 | - Default stdout output is valid JSON |
| 24 | - Stress: 50-file commit |
| 25 | - Security: path-traversal and ANSI in treeish |
| 26 | - Performance: duration_ms plausible |
