| 1 | """Tests for ``muse code add`` / ``muse code reset`` and stage-aware commit/status. |
| 2 | |
| 3 | Coverage matrix: |
| 4 | |
| 5 | Unit tests (pure functions): |
| 6 | - _split_into_hunks: empty diff, single hunk, multi-hunk, trailing newlines |
| 7 | - _apply_hunks_to_bytes: accept all, accept none, accept partial, new-file |
| 8 | - _infer_mode: all three modes (A / M / D) |
| 9 | - _colorize_hunk: color escape codes present for +/- lines |
| 10 | |
| 11 | Integration tests (CLI round-trips): |
| 12 | - muse code add <file> — stages modified file as mode M |
| 13 | - muse code add <new-file> — stages new file as mode A |
| 14 | - muse code add . — stages everything |
| 15 | - muse code add -A — stages all including new files |
| 16 | - muse code add -u — stages tracked files only (excludes untracked) |
| 17 | - muse code add -u — stages deleted files as mode D |
| 18 | - muse code add <dir> — expands directory recursively |
| 19 | - muse code add --dry-run — shows intent without writing |
| 20 | - muse code add -v — verbose per-file output |
| 21 | - muse code add (re-stage) — updates object_id when file changes again |
| 22 | - nonexistent path — exits non-zero |
| 23 | - wrong domain — exits non-zero |
| 24 | |
| 25 | Stage-aware commit: |
| 26 | - Only staged files appear in the committed snapshot |
| 27 | - Unstaged changes do NOT appear in the committed snapshot |
| 28 | - Stage is cleared after a successful commit |
| 29 | - Staged deletion removes file from next commit |
| 30 | |
| 31 | muse status — three-bucket view: |
| 32 | - "Changes staged for commit" section present |
| 33 | - "Changes not staged" section present |
| 34 | - Untracked files listed |
| 35 | - --format json includes staged/unstaged/untracked keys |
| 36 | - --json format |
| 37 | |
| 38 | muse code reset: |
| 39 | - reset <file> — unstages that file only |
| 40 | - reset HEAD <file> — Git-syntax alias works |
| 41 | - reset (no args) — clears everything |
| 42 | - reset when nothing staged — exits cleanly |
| 43 | |
| 44 | Resilience: |
| 45 | - Corrupt stage.json degrades gracefully (read_stage returns {}) |
| 46 | - Staging a file outside the repo root is rejected |
| 47 | |
| 48 | Stress: |
| 49 | - Staging 100 files in one shot |
