1 """Section 11 — Merge Proposals: 7-layer test suite.
2
3 Complements the existing test_musehub_proposals.py (47 tests) by adding
4 exhaustive coverage across all 7 layers:
5
6 Layer 1 Unit
7 - TestUnitRiskScoring: compute_risk score/band arithmetic, edge cases
8 - TestUnitBandThresholds: _band boundaries (25/50/75)
9 - TestUnitInferListRiskBand: branch prefix mapping
10 - TestUnitScoreLabel: score_label at every threshold
11 - TestUnitProposalRisk: as_dict round-trip, band_color values
12
13 Layer 2 Integration
14 - TestIntegrationSequentialNumbers: proposal_numbers are 1-based and per-repo
15 - TestIntegrationListStateFilter: open/merged/closed/all filter accuracy
16 - TestIntegrationListPagination: page + per_page on proposals list
17 - TestIntegrationSourceBranchDeletedOnMerge: branch removed post-merge
18
19 Layer 3 E2E
20 - TestE2EProposalLifecycle: create → request reviewers → approve → merge
21 - TestE2ECommentThreading: top-level + reply structure in list response
22 - TestE2EReviewWorkflow: pending → changes_requested → approved update
23 - TestE2EClose: proposal stays open (no close endpoint) — close via merge only
24
25 Layer 4 Stress
26 - TestStress: 50 proposals in a repo, 30 comments on one proposal
27
28 Layer 5 Data Integrity
29 - TestDataIntegrity: cross-repo isolation, merge idempotence, merged_at set,
30 merge_commit_id persisted, reviewer uniqueness per proposal
31
32 Layer 6 Security
33 - TestSecurity: create/merge/comment/reviewer endpoints require auth;
34 cross-repo proposal_id not accessible; title max-length enforced
35
36 Layer 7 Performance
37 - TestPerformance: list 100 proposals <500ms, list 100 comments <300ms
