| 1 | """Supercharge tests for ``muse code checkout-symbol`` — agent-usability gaps. |
| 2 | |
| 3 | The existing test_cmd_checkout_symbol.py already covers correctness, JSON |
| 4 | schema, E2E round-trips, stress, and post-write verification. This file |
| 5 | targets only the gaps those tests leave open: |
| 6 | |
| 7 | Coverage matrix |
| 8 | --------------- |
| 9 | - --json / -j: -j alias works identically to --json |
| 10 | - exit_code: all three JSON paths (no-op, dry-run, write) include exit_code = 0 |
| 11 | - duration_ms: all three JSON paths include non-negative float duration_ms |
| 12 | - TypedDicts: _CheckoutSymbolOutputJson gains exit_code/duration_ms annotations |
| 13 | - Docstrings: run() docstring mentions exit_code and duration_ms |
| 14 | - ANSI: JSON output never contains terminal escape sequences |
| 15 | - Performance: duration_ms stays under 2000 ms for a small repo |
