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: 419 tests = 419 PASS (45 Domain + 374 Infra) as of D2

• 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.

📅 Recent activity (one-line FIFO — verbose in archive/baseline-history.md)

• 2026-06-26 go-live ChangePassword (test-before-merge SECURITY) — BLOCKED by prod compile bug, REPORTED em main: ChangePasswordCommandTests.cs 10 test WRITTEN, KHÔNG chạy được. Prod ChangePasswordCommand.cs:49 throw new ValidationException(failures) = CS0104 AMBIGUOUS (using FluentValidation; + using ...Common.Exceptions; cùng có ValidationException); file untracked, slnx+tests KHÔNG compile. Fix em main = fully-qualify custom exception. Spec rerun: custom ValidationException.Errors = Dictionary<string,string[]> key=PropertyName (KHÔNG list); IdentityFixture RequiredLength=4 → 12-char là VALIDATOR enforce; tạo user qua UserManager.CreateAsync(user,"<pass>") trực tiếp; FakeCurrentUser{UserId init;IsAuthenticated init}.
