Raw Blame History

Test-Specialist Agent — Persistent Memory

Persistent diary cross-session. Auto-injected first ~200 lines at spawn (L1 HOT). Update BEFORE every stop. Tiered Memory v1: L1 HOT soft-cap ~30KB · L2 archive/ on-demand · L3 RAG search_memory just-in-time. Keep entry ≤ 1.5K chars (gotcha #53). NEW agent S39 (2026-05-29) — dedicated test layer (tách khỏi implementer Case 3).

🎯 Role baseline

WRITE specialist độc quyền tests/**. xUnit + FluentAssertions 7.2 + EF SQLite TestApplicationDbContext + IdentityFixture. Tools: Read, Edit, Write, Bash, Grep, Glob + 5 RAG. Skills: contract-workflow + permission-matrix.

🚫 Split boundary

  • ✅ MINE: tests/SolutionErp.{Domain,Infrastructure}.Tests/**
  • ❌ NOT: production code src/Backend/** + fe-*/** → test reveal bug → REPORT em main, KHÔNG fix
  • ❌ NOT: decide WHAT to test (test plan) → em main + reviewer chốt priority

📊 Baseline: 495 tests = 495 PASS (45 Domain + 450 Infra) as of S116 (re-grounded from code; was 477@S113)

  • Count history + verbose per-session test-design notes (S54→D2): archive/baseline-history.md (L2, on-demand).
  • Latest (D2): +6 PE Mig 58 multi-winner — CreateContractFromEvaluationMultiWinnerTests.cs (5, 1→N HĐ per IsWinner, GiaTri per-winner=quote-total / single=legacy-budget-sum) + PeListWinnerNamesProjectionTests.cs (1, EF collection-projection translation-smoke). No prod bug.

Pattern S67: private-static seed/init → invoke qua REFLECTION (GetMethod(name, NonPublic|Static) + Invoke(null, [db, roleManager, NullLogger.Instance])); seed MenuItem rows TRƯỚC Permission (FK MenuKey→MenuItem.Key Cascade, SQLite Error 19 nếu thiếu). Cycle-guard test: SqliteDbFixture đủ (no User); rollup-count test cần IdentityFixture. Run: dotnet test SolutionErp.slnx --nologo --verbosity minimal -p:BuildInParallel=false -maxcpucount:1 (MSBuild OOM → serialize build)

⚠️ Pattern: deduction hook FK → seed LeaveType cho terminal test (S43)

LeaveBalance→LeaveType Restrict FK. ApproveLeaveRequest terminal (DaDuyet) insert LeaveBalance → test tới DaDuyet PHẢI seed 1 LeaveType + LeaveRequest.LeaveTypeId=type.Id (random Guid→FK fail SQLite 19). Non-terminal (advance/reject/return/OtRequest) KHÔNG cần. BuildLeave optional leaveTypeId default random. Year=StartDate.Year. Negative OK (no quota guard). Query lazy-synth Entitled=DaysPerYear khi 0 row.

⏱️ Timing rules (docs/rules.md §7)

  • Feature mới = test-after (UAT ổn → viết, Phase 9 skip per feedback_uat_skip_verify)
  • Bug fix = test-before BẮT BUỘC (reproduce → fix)
  • Critical algo = test-before merge (codegen/guard/financial/security)
  • Skip: DTO mapping, CRUD master, FE snapshot

📋 Patterns proven (apply confidently)

Pattern 10 Reflection authz regression (~50 LOC)

Catch class-level [Authorize(Policy=...)] regression: typeof(Ctrl).GetCustomAttribute<AuthorizeAttribute>().Policy.Should().Be(...). KHÔNG WebApplicationFactory heavy. Cho gotcha #44 silent 403.

Pattern 11 Test infra helper cookie-cutter

SeedWorkflowAsync (1 Step DepartmentId=null skip FK + 2 Levels) + SeedApproversAsync (N user fix.CreateUserAsync). Reusable PE/Contract/Proposal workflow test.

Pattern 12 InternalsVisibleTo

Expose internal helper via <InternalsVisibleTo Include="SolutionErp.Infrastructure.Tests" /> csproj.

Spec drift detection BEFORE write (S34 lesson)

Test theo CODE (single source truth), document mismatch header comment + report. Vd soft-delete UNIQUE: code chặn opt-out → test theo code, flag drift.

gotcha #48 SQLite tie-break

OrderByDescending(CreatedAt).First() pick wrong khi 2+ Add() cùng CreatedAt frozen-clock → discriminator filter .Where(Summary.Contains("Chuyển phase")) BEFORE OrderBy.

🎯 Coverage gap backlog (priority — Reviewer flagged S36)

  1. ✅ DONE S45 — HrmConfig Holiday composite UNIQUE (Year,Date): 7 test (HrmConfigHolidayTests.cs) + surfaced Mig 43 filtered-index fix
  2. ✅ DONE S45 — EmployeeSatellite FK invariant + soft-delete + cascade: 10 test (EmployeeSatelliteTests.cs)
  3. ✅ DONE S45 — gotcha #44 authz regression EmployeesController + HrmConfigsController: 10 test (extend AuthorizePolicyRegressionTests.cs)
  4. Phase 10.3 Proposal ApproveV2 (S37) + Workflow Apps skeleton (S38) — test-after khi UAT confirm
  5. gotcha #57 (S51+S52 REPRODUCED): HRM HrmConfigFilteredUniqueTests 2 RED (LeaveType+Shift+OtPolicy) → em main Mig 45 .HasFilter GREEN. S52 EXT Master MasterCatalogFilteredUniqueTests 3 RED (Department cfg:18 / Project:19 / Supplier:24 bare .IsUnique()) → pending em main fix migration. Vehicle+Driver (Mig 44) ĐÃ filtered. Pattern: seed IsDeleted=true slot + Create cùng Code → assert active==1 + IgnoreQueryFilters all==2.

Existing S112 file UNTOUCHED (re-baked ExpectedHeaderTokens=30 \n-token → real tokens khớp → Case9 tự flip LayoutValid=true). Dedup precedence existing-MST→existing-Code→batch-MST→batch-Code→New: strip-ws-normalize MST-match · 2-blank-MST=2-insert (blank không index) · same-MST-batch=1-insert+fill-null-skip · Code-backstop CI (S112: dedup ở SERVICE OrdinalIgnoreCase, SQLite BINARY KHÔNG bắt "backstop"≈"BACKSTOP" → xanh=chứng không dựa DB) · MST→A/Code→B = MST-precedence WINS, no silent-clobber (FillNulls skip Code → A.Code giữ, B untouched).

ListSuppliers Published t/f/null · GetSupplier DTO.IsPublic. 🔴 BUG: NewSupplier Code=r.Code!.Trim() → NRE khi row.Code==NULL (path R4 nháp: parser sinh null ô rỗng + preview classify New no-error → confirm NRE → 500 CẢ batch dbCount=0).

  • D4 (2026-07-12) PE sign-off A1 + EDGE-5 + opinion-history TEST-BEFORE-MERGE (critical-algo bug-fix + security) — 450→458 PASS (+8 Infra, 4 updated in-place), no-red, NO prod bug: BE đổi ApplyDrafterBypassOnSubmitAsync sang A1 trong PeSubmitGuardAndBypassTests.cs. 4 updated + RENAMED (tên cũ misleading): drafter bypass CHỈ cấp NV dưới THUẦN (Order<minOwn); pointer DỪNG tại minOwn (người soạn ký TAY qua ApproveV2Async); KHÔNG auto-sign opinion chính chủ / KHÔNG auto-terminal-on-submit / KHÔNG auto nhảy Bước. minOwn=1 (drafter Cấp1 hoặc non-contiguous Cấp1+3) → bypass RỖNG (opinion=0, AutoApprove=0). 8 new: A1 happy-path (drafter ký Cấp2 comment THẬT — canned "duyệt tự động" đã GỠ khỏi prod, grep 0-match) · non-contiguous full-manual-chain đúng thứ tự · EDGE-5 ×4 (non-admin Reject từ DaDuyet/TuChoi → Conflict "trạng thái kết thúc"; Admin + system[actorUserId=null+AutoApprove] MIỄN → fall-through "không hỗ trợ" chứng minh qua-guard) · opinion-history ×2 (re-sign đè opinion non-empty → đúng 1 Changelog Workflow/Update EntityId=level.Id ContextNote chứa comment cũ; first-sign / đè-rỗng → 0 row, filter theo EntityId==levelId loại được Trả-lại-changelog EntityId=null).

  • D3 (2026-07-12) Supplier Excel-import BE (Phase B) TEST-BEFORE-MERGE (CRITICAL-ALGO + case-collation bug-class) — 440→450 PASS (+10 Infra), no-red, NO prod bug: new Services/SupplierExcelImportServiceTests.cs (10 [Fact]). Case-collation (THE bug): ConfirmAsync lowercase truonggiang vs DB TRUONGGIANG → Inserted=0/Updated=1/count=1 (dedup ở SERVICE OrdinalIgnoreCase, KHÔNG dựa DB — SQLite fixture BINARY collation KHÔNG bắt CI-dup, prod SQL Server CI thì có → nếu Ordinal = 500 batch); Preview classify Update. Fill-nulls SAFE (non-null giữ / null điền). All-or-nothing (1 hard-error→Committed=false + DB unchanged). MapType unknown→NhaCungCap+warning · emoji-strip status → DangHoatDong · valid-layout absolute-index parse (LinkGuq RAW backslash) · no-column-drift (col9 empty→col12 vẫn TaxCode) · #REF! literal→null. Pattern (reuse): header xlsx dựng từ ExpectedHeaderTokens qua REFLECTION (GetField(NonPublic|Static)) → valid-layout test tự đồng bộ khi tokens sửa; ClosedXML in-mem XLWorkbook.AddWorksheet+ws.Cell(r,c).Value=string GIỮ TEXT (0.105 no numeric-coercion → leading-zero safe). Spec-drift FLAGGED (không phải bug): ExpectedHeaderTokens = BEST-GUESS ≠ 30 real row-4 token → Case 9 dynamic LayoutValid==(NormalizeJoin(real)==NormalizeJoin(reflected)) robust 2-chiều, hiện LayoutValid=false; close-review sẽ sửa tokens → test tự flip true.

  • S97 (2026-07-01) PE EndsBeforeCeo CONFIG→RUNTIME (bug anh Kiệt FDC, spec-change test) — 440 PASS no-red, NET +0 [Fact] (extend in-place): em-main BE thêm PurchaseEvaluation.EndedByLevelFinalize (Mig 60) set true DUY NHẤT nhánh level-finalize ApproveV2Async. ListApproved (DaDuyet-only) đọc THẲNG field (CreateContractFromEvaluationFeatures.cs:196); List/Inbox ternary Phase==DaDuyet ? field : subquery.

Reflection harness mirror Office/Hrm seed test. Gotcha: OfficeModulePermissionSeedTests + HrmProfilePermissionSeedTests VẪN PASS dù prod đã TẮT 2 call grant — vì test invoke method-CÔ-LẬP qua reflection (private static giữ cho reversibility), KHÔNG chạy SeedAsync chain; thêm 1 dòng header note mỗi file. (ChangePassword S91 10-test ĐÃ merge → trong baseline 431.)
