| 1 | """Supercharge tests for ``muse code deps`` — agent-usability gaps. |
| 2 | |
| 3 | The existing TestDeps suite in test_code_commands.py covers correctness, |
| 4 | JSON schemas, all flags (--reverse, --count, --filter, --depth, --transitive), |
| 5 | file mode and symbol mode, and security (path traversal, empty file rel). |
| 6 | |
| 7 | This file targets only the gaps those tests leave open: |
| 8 | |
| 9 | Coverage matrix |
| 10 | --------------- |
| 11 | - --json / -j: -j alias works identically to --json (all 6 JSON paths) |
| 12 | - exit_code: JSON output includes exit_code = 0 on success (all 6 paths) |
| 13 | - duration_ms: JSON output includes non-negative float duration_ms (all 6 paths) |
| 14 | - TypedDicts: _DepsFileJson and _DepsSymbolJson carry exit_code/duration_ms |
| 15 | - Docstrings: run() docstring mentions exit_code and duration_ms |
| 16 | - ANSI: JSON output never contains terminal escape sequences |
| 17 | - Performance: duration_ms stays under 2000 ms for a small repo |
| 18 | |
| 19 | Six JSON paths exercised |
| 20 | ------------------------ |
| 21 | 1. File mode, forward: --json billing.py → {path, imports, ...} |
| 22 | 2. File mode, reverse: --reverse --json billing.py → {path, imported_by, ...} |
| 23 | 3. Symbol mode, forward depth=1 --json billing.py::func → {address, depth, calls, ...} |
| 24 | 4. Symbol mode, forward multi: --transitive --json → {address, by_depth, ...} |
| 25 | 5. Symbol mode, reverse depth=1 --reverse --json symbol → {address, called_by, ...} |
| 26 | 6. Symbol mode, reverse multi: --reverse --transitive → {address, by_depth, ...} |
