20 days ago
| 1 | """Comprehensive hardening tests for ``muse bisect``. |
| 2 | |
| 3 | Covers: |
| 4 | - Unit: _toml_escape, _load_state symlink guard, size cap, _save_state injection |
| 5 | - Security: branch TOML injection, symlink state file, oversized state, ANSI |
| 6 | sanitization, error routing to stderr, null bytes in refs |
| 7 | - JSON schema: all subcommands (start, bad, good, skip, log, reset, run) |
| 8 | - Integration: --json round-trips, get_bisect_next public API, session lifecycle |
| 9 | - E2E: symbol-scoped bisect, run subcommand NDJSON, reset --json, log --json |
| 10 | - Stress: 200-commit chain, concurrent read-only queries |
