| 1 | """Comprehensive tests for muse ls-remote. |
| 2 | |
| 3 | The command contacts a remote via HttpTransport. All tests mock that |
| 4 | transport — no real network is required. |
| 5 | |
| 6 | Coverage: |
| 7 | - Unit: _FORMAT_CHOICES, register args |
| 8 | - Integration: JSON/text output, --json shorthand, multiple branches, |
| 9 | empty repo, default-branch marker, URL override, format error |
| 10 | - Security: ANSI in remote branch names / commit IDs, format error → stderr, |
| 11 | no tracebacks on transport failures |
| 12 | - Stress: 200 branches, 200 sequential calls |
