| 1 | """Supercharge tests for ``muse code languages`` — agent-usability gaps. |
| 2 | |
| 3 | The existing test_code_language_config.py covers the language detection |
| 4 | machinery (AST parser, CodeConfig, adapter routing) but has zero CLI tests. |
| 5 | |
| 6 | This file covers the CLI command end-to-end: |
| 7 | |
| 8 | Coverage matrix |
| 9 | --------------- |
| 10 | - --json / -j: -j alias (was missing — caused argparse error) |
| 11 | - exit_code: both JSON paths (snapshot + diff) include exit_code = 0 |
| 12 | - duration_ms: both JSON paths include non-negative float duration_ms |
| 13 | - TypedDicts: _SnapshotOutputJson and _DiffOutputJson carry all envelope fields |
| 14 | - Docstrings: run() docstring mentions exit_code and duration_ms |
| 15 | - Snapshot JSON: shape, required keys, language entry structure |
| 16 | - Diff JSON: shape, required keys, diff entry structure |
| 17 | - --sort: name / files / symbols all accepted; output ordering correct |
| 18 | - --include-imports: import pseudo-symbols added to counts |
| 19 | - --commit: historical snapshot accepted; bad ref exits cleanly |
| 20 | - --diff: diff mode activates; bad ref exits cleanly |
| 21 | - ANSI: no escape codes in JSON output |
| 22 | - Performance: duration_ms < 5000 ms on a small repo |
