| 1 | """Comprehensive hardening tests for ``muse revert``. |
| 2 | |
| 3 | Covers all changes introduced in the revert command review: |
| 4 | |
| 5 | Unit |
| 6 | ---- |
| 7 | - Parser flags: --dry-run, --force, --no-commit, --json/-j |
| 8 | - Dead-code removal: _read_branch absent, pathlib not imported |
| 9 | - All flags present and correctly typed in register() |
| 10 | |
| 11 | Integration |
| 12 | ----------- |
| 13 | - Error messages routed to stderr, stdout clean |
| 14 | - JSON schema identical and complete for all code paths |
| 15 | (normal, --no-commit, --dry-run) |
| 16 | - --dry-run performs no writes (branch ref, workdir, reflog unchanged) |
| 17 | - --no-commit applies workdir changes without advancing the branch ref |
| 18 | - Reflog entry appended after normal revert |
| 19 | - Write ordering: write_commit fires before apply_manifest in source |
| 20 | - validate_branch_name called in run() |
| 21 | - target.message sanitized before embedding in revert commit message |
| 22 | - ref sanitized in "not found" error |
| 23 | |
| 24 | Agent-UX (supercharge additions) |
| 25 | --------------------------------- |
| 26 | - duration_ms present in all JSON responses (success and error) |
| 27 | - exit_code present in all JSON responses (success and error) |
| 28 | - files_added / files_modified / files_removed in all success JSON |
| 29 | - Correct file-level diff for added, modified, deleted file reverts |
| 30 | - --no-commit stages changes so muse commit picks them up |
| 31 | - Reverting to an empty snapshot (no parent files) works without crash |
| 32 | - HEAD ref resolves correctly |
| 33 | - Data integrity: file content verified after revert |
| 34 | |
| 35 | End-to-end |
| 36 | ---------- |
| 37 | - Text output format |
| 38 | - JSON output format with full schema verification |
| 39 | - --force bypasses dirty-workdir guard |
| 40 | |
| 41 | Security |
| 42 | -------- |
| 43 | - ANSI escape codes in ref rejected / sanitized in error |
| 44 | - ANSI in original commit message not propagated to revert commit message |
| 45 | - Unknown flags exit non-zero |
| 46 | |
| 47 | Stress |
| 48 | ------ |
| 49 | - Revert across a chain of 200 commits |
| 50 | - 50 sequential reverts in the same repo |
| 51 | - Concurrent reverts to isolated repos |
