## 🎯 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: 509 tests = 509 PASS (45 Domain + 464 Infra) as of S118b (was 505@S118; +4 Infra ReportsController company-wide-report authz-regression, filtered-run 19/19, full 509/509)
- Count history + verbose per-session test-design notes (S54→D2): [archive/baseline-history.md](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.
