| 1 | """Tests for MuseHub merge proposal endpoints. |
| 2 | |
| 3 | Covers every acceptance criterion from issues #41, #215: |
| 4 | - POST /repos/{repo_id}/proposals creates proposal in open state |
| 5 | - 422 when from_branch == to_branch |
| 6 | - 404 when from_branch does not exist |
| 7 | - GET /proposals returns all proposals (open + merged + closed) |
| 8 | - GET /proposals/{proposal_id} returns full proposal detail; 404 if not found |
| 9 | - GET /proposals/{proposal_id}/diff returns five-dimension musical diff scores |
| 10 | - GET /proposals/{proposal_id}/diff graceful degradation when branches have no commits |
| 11 | - POST /proposals/{proposal_id}/merge creates merge commit, sets state merged |
| 12 | - POST /proposals/{proposal_id}/merge accepts squash and rebase strategies |
| 13 | - 409 when merging an already-merged proposal |
| 14 | - All endpoints require valid MSign auth |
| 15 | - affected_sections derived from commit message text, not structural score heuristic |
| 16 | - build_proposal_diff_response / build_zero_diff_response service helpers produce valid output |
| 17 | |
| 18 | All tests use the shared ``client``, ``auth_headers``, and ``db_session`` |
| 19 | fixtures from conftest.py. |
