+# Sprint 11 Analysis — Quality Foundation: Backend Test Coverage
+
+**Date:** 2026-06-15
+**Sprint Theme:** Quality Foundation — Backend Test Coverage
+**Author:** Patrick Plate / Roo (Architect)
+**Status:** Draft v1
+
+---
+
+## 1. Current State Assessment
+
+### 1.1 Codebase Metrics
+
+| Metric | Value |
+|--------|-------|
+| Backend LOC (Java) | ~29,000 |
+| Service classes | 42 (main) + 12 (bankimport) + 19 (report generators) |
+| Existing unit tests | 9 test classes in `cannamanage-service` |
+| Existing integration tests | 6 test classes in `cannamanage-api` |
+| Existing Playwright E2E tests | 202 |
+| Estimated current line coverage | ~12% |
+| Target line coverage | ≥80% overall, ≥90% for financial/compliance |
+
+### 1.2 Existing Test Inventory
+
+**Unit Tests (`cannamanage-service/src/test/`):**
+
+| Test Class | Service Under Test | Approx. Coverage |
+|------------|-------------------|-----------------|
+| `ClubServiceTest` | ClubService | Partial |
+| `ComplianceServiceTest` | ComplianceService | Good (quota enforcement) |
+| `EmailServiceTest` | EmailService | Basic |
+| `PdfReportGeneratorTest` | PdfReportGenerator | Basic |
+| `PortalServiceTest` | PortalService | Partial |
+| `PreventionOfficerServiceTest` | PreventionOfficerService | Good |
+| `ReportServiceTest` | ReportService | Partial |
+| `StaffServiceTest` | StaffService | Partial |
+| `TokenRevocationServiceTest` | TokenRevocationService | Good |
+
+**Integration Tests (`cannamanage-api/src/test/`):**
+
+| Test Class | Scope |
+|------------|-------|
+| `AbstractIntegrationTest` | Base class (Testcontainers PostgreSQL) |
+| `AuthIntegrationTest` | Full auth flow |
+| `PortalIntegrationTest` | Member portal endpoints |
+| `ReportIntegrationTest` | Report generation endpoints |

+| `AuthControllerIntegrationTest` | Auth controller |
+| `ClubControllerTest` | Club CRUD |
+| `ComplianceControllerIntegrationTest` | Compliance endpoints |
+| `StaffPermissionCheckerTest` | Permission checker logic |
+
+### 1.3 Untested Services (Coverage Gaps)
+
+**Critical — Zero Test Coverage:**
+
+| Service | LOC | Complexity | Risk |
+|---------|-----|-----------|------|
+| `FinanceService` | 371 | High (ledger, payments, fees) | 🔴 Financial |
+| `PaymentMatchingService` | 507 | Very High (scoring algorithm) | 🔴 Financial |
+| `BankImportService` | ~400 | High (stateful session) | 🔴 Financial/GoBD |
+| `Mt940Parser` | ~300 | High (state machine) | 🔴 Financial |
+| `Camt053Parser` | ~250 | High (StAX XML) | 🔴 Security (XXE) |
+| `CsvBankParser` | ~200 | Medium | 🟡 Financial |
+| `RetentionService` | ~200 | Medium (GDPR logic) | 🔴 Compliance |
+| `ReportGeneratorService` | ~150 | Medium (dispatch) | 🟡 Compliance |
+| `EurReportGenerator` | ~300 | High (§4(3) EStG) | 🔴 Financial |
+| `AnnualAuthorityReportGenerator` | ~250 | High (CanG §26) | 🔴 Compliance |
+| `AssemblyService` | ~350 | High (quorum, voting) | 🟡 Legal |
+| `EventService` | ~250 | Medium (RSVP, iCal) | 🟢 Standard |
+| `ForumService` | ~200 | Medium | 🟢 Standard |
+| `InfoBoardService` | ~150 | Low | 🟢 Standard |
+| `NotificationDispatchService` | ~200 | Medium (fan-out) | 🟡 Reliability |
+| `JwtService` | ~120 | Medium (crypto) | 🔴 Security |
+| `LoginRateLimiter` | ~80 | Low | 🔴 Security |
+| `TenantFilterAspect` | ~60 | Low (AOP) | 🔴 Security |
+| `DocumentService` | ~200 | Medium (file I/O) | 🔴 Security |
+
+### 1.4 Test Infrastructure Status
+
+| Infrastructure | Status |
+|---------------|--------|
+| JUnit 5 | ✅ Available (via spring-boot-starter-test) |
+| Mockito | ✅ Available (via spring-boot-starter-test) |
+| AssertJ | ✅ Available (explicit dependency) |
+| Testcontainers PostgreSQL | ✅ Available + configured |
+| AbstractIntegrationTest base class | ✅ Exists with helper methods |
+| JaCoCo coverage plugin | ❌ Not configured |
+| Test profiles (application-test.properties) | ✅ Exists |
+| Integration profile (application-integration.properties) | ✅ Exists |
+
+---
+
+## 2. Risk Analysis
+
+### 2.1 Why 12% Coverage is a Production Blocker
+
+| Risk | Impact | Probability | Mitigation |
+|------|--------|-------------|-----------|
+| Financial calculation bug (rounding, fee logic) | Loss of member trust, incorrect Kassenbuch | High | Unit tests for FinanceService with cent-precision assertions |
+| Bank import data corruption (GoBD violation) | Legal liability under §147 AO | Medium | Integration tests for immutable session lifecycle |
+| Payment matching false positive (wrong member) | Incorrect bookkeeping, member disputes | Medium | Unit tests with realistic German bank statement data |
+| MT940 parser crash on edge cases | Import failure blocks payment reconciliation | High | Fuzz-style tests with malformed input |
+| GDPR retention logic error | Supervisory authority fine (up to 4% revenue) | Low | Unit tests for anonymization completeness |
+| Quota enforcement bypass | CanG violation, club loses license | Medium | Already tested (ComplianceServiceTest) — verify edge cases |
+| JWT token validation bypass | Unauthorized access | Low-Medium | Unit tests for expiry, tampering, revocation |
+| Tenant isolation breach | Data leak between clubs | Critical | Already tested (TenantIsolationTest) — extend |
+
+### 2.2 Coverage Targets by Risk Category
+
+| Category | Target | Rationale |
+|----------|--------|-----------|
+| Financial (FinanceService, BankImport, Parsers, Matching) | ≥90% | Money handling requires near-complete coverage |
+| Compliance (Retention, ComplianceService, Reports) | ≥90% | Regulatory requirements |
+| Security (JWT, RateLimiter, Tenant, Document) | ≥80% | Attack surface minimization |
+| Core Business (Assembly, Events, Forum, InfoBoard) | ≥75% | Functional correctness |
+| Infrastructure (Notifications, Schedulers) | ≥60% | Reliability baseline |
+
+---
+
+## 3. Testing Strategy
+
+### 3.1 Test Pyramid
+
+```
+ /‾‾‾‾‾‾‾‾‾‾‾‾\
+ / Playwright \ 202 existing (unchanged)
+ / E2E (202) \
+ /____________________\
+ / \
+ / Integration (~12) \ ~12 new (Testcontainers)
+ / API + DB flows \
+ /__________________________\
+/ \
+/ Unit Tests (~95+) \ ~95 new (Mockito)
+/ Service logic isolation \
+/________________________________\
+```
+
+### 3.2 Unit Test Approach
+
+- **Pattern:** JUnit 5 + Mockito + AssertJ (matching existing ComplianceServiceTest style)
+- **Naming:** `test__()` with `@DisplayName`
+- **Structure:** Given-When-Then with clear section comments
+- **Mocking:** All repository dependencies mocked; test pure business logic
+- **Edge cases:** null inputs, boundary values, German locale specifics (umlauts, date formats)
+
+### 3.3 Integration Test Approach
+
+- **Base class:** Extend existing `AbstractIntegrationTest` (Testcontainers PostgreSQL)
+- **Scope:** Full request → DB → response cycles
+- **Auth:** Use helper methods to create users and obtain JWT tokens
+- **Data isolation:** Each test creates its own club/user context
+- **Cleanup:** `@Transactional` rollback or manual cleanup in `@AfterEach`
+
+### 3.4 Coverage Measurement
+
+- **Tool:** JaCoCo Maven plugin
+- **Report:** HTML + XML (for CI parsing)
+- **Enforcement:** `` element with minimum 60% line coverage
+- **Exclusions:** Generated code, DTOs, enums, configuration classes
+
+---
+
+## 4. Sprint Scope
+
+### 4.1 In Scope
+
+- 296+ new unit tests across 30+ service classes (includes report generators, schedulers, CRUD services)
+- 29+ new integration tests for critical flows (incl. SecurityConfig and Flyway migration verification)
+- JaCoCo plugin configuration with 80% enforcement
+- Maven Surefire parallelization (forkCount=2) for build speed
+- Test fixtures and builders for realistic German data (incl. real Sparkasse MT940)
+- Coverage from 12% → 80%+ overall (realistically achievable with +70 easy-win tests in v3)
+
+### 4.2 Out of Scope
+
+- New features
+- Frontend changes
+- Playwright test additions
+- CI/CD pipeline changes (deferred to Sprint 12)
+- Performance testing
+
+---
+
+## 5. Dependencies
+
+| Dependency | Status | Action |
+|-----------|--------|--------|
+| Testcontainers | ✅ Already in POM | None |
+| JaCoCo | ❌ Missing | Add to parent POM |
+| Test fixtures (MT940 samples, CAMT053 XML) | ❌ Missing | Create in src/test/resources |
+| Mockito (for unit tests) | ✅ via starter-test | None |
+| AssertJ | ✅ Explicit dependency | None |
+
+---
+
+## 6. Success Criteria
+
+| Criterion | Threshold | Measurement |
+|-----------|-----------|-------------|
+| Overall line coverage | ≥80% | JaCoCo report |
+| Financial module coverage | ≥90% | JaCoCo per-package |
+| Compliance module coverage | ≥90% | JaCoCo per-package |
+| Security module coverage | ≥85% | JaCoCo per-package (boosted by GlobalExceptionHandler tests) |
+| Core business coverage | ≥75% | JaCoCo per-package |
+| Infrastructure coverage (Schedulers + Notifications) | ≥70% | JaCoCo per-package |
+| All tests pass | 100% green | `mvn test` exit code 0 |
+| Total backend tests | ≥345 | Surefire report count |
+| No new features introduced | 0 feature commits | Git log review |
+| Build time increase | ≤3 minutes | Maven timing (with forkCount=2) |

+| 1 | CanG §26 annual authority report testing | ✅ | Expanded to 8 tests — now includes U21 marking and quota breach highlighting |
+| 2 | Quota enforcement boundary testing | ✅ | NEW: 10 dedicated ComplianceServiceTest extensions cover every boundary (25g daily, 50g monthly, U21 10g, THC 15%) |
+| 3 | EÜR (§4/3 EStG) correctness | ✅ | EurReportGeneratorTest expanded to 8 tests with performance and single-cent edge case |
+| 4 | Kassenbuch GoBD compliance | ✅ | BankImportServiceTest: 14 tests including concurrent upload and undo confirm |
+| 5 | Distribution THC limits (U21 vs adult) | ✅ | ComplianceServiceTest now has explicit boundary tests for U21 THC% limits |
+| 6 | Financial amounts in cents | ✅ | FinanceServiceTest: added Integer.MAX_VALUE boundary and 1/3 split (odd-cent) tests |
+| 7 | Cross-midnight quota reset | ✅ | NEW: testQuota_CrossMidnight_ResetsDailyCounter ensures day boundary correctness |
+
+**Findings:** None blocking. The v2 plan significantly strengthens compliance coverage. The addition of exact boundary tests for every CanG quota (daily/monthly/U21/THC%) is excellent — these are the exact edge cases that could lead to regulatory violations if miscalculated.

+| 1 | JaCoCo plugin configuration | ✅ | Correct — 80% threshold, appropriate exclusions |
+| 2 | Maven Surefire parallelization | ✅ | Added forkCount=2, addresses v1 build time concern |
+| 3 | Testcontainers integration | ✅ | Extended to 25 integration tests (up from 12) |
+| 4 | Test module separation | ✅ | Unit tests in cannamanage-service, integration in cannamanage-api |
+| 5 | Build time impact | ⚠️ | 255 new tests with forkCount=2 — may push past 7min target |
+| 6 | Concurrent test scenarios | ⚠️ | Multiple concurrent test methods (PaymentMatching, BankImport, Assembly) — need careful thread safety in test setup |
+| 7 | Migration integration test | ✅ | NEW: MigrationIntegrationTest validates Flyway schema |
+
+**Findings:**
+
+⚠️ **SHOULD (non-blocking):** With 275 total tests, even with `forkCount=2`, build time may approach 7 minutes. If it exceeds the target, consider:
+- Adding `methods` for unit tests (safe since each test is independent)
+- Splitting integration tests into a separate Maven profile activated by `-Pintegration`
+
+⚠️ **SHOULD (non-blocking):** Concurrent test methods (`testMatch_ConcurrentMatching_ThreadSafe`, `testConcurrentUpload_SameFile_OnlyOneSucceeds`, `testConcurrentVotes_AllCounted`) require careful setup. Recommend using `CountDownLatch` + `ExecutorService` pattern with explicit timeout to avoid flaky behavior.

+| 2 | Exact boundary date verification | ✅ | NEW: testAnonymize_MemberLeftExactlyAtBoundary_NotEligible — critical for GDPR |
+| 3 | Concurrent anonymization safety | ✅ | NEW: testAnonymize_ConcurrentRun_Idempotent prevents double-processing |
+| 4 | Financial data immutability | ✅ | FinanceIntegrationTest: testLedgerImmutability_CannotDeleteEntry |
+| 5 | GoBD session lifecycle | ✅ | BankImportIntegrationTest: 7 tests (up from 4) with concurrent and split scenarios |
+| 6 | Data isolation in all paths | ✅ | TenantFilterAspectTest: expanded to 8 tests covering every controller type |
+| 7 | Flyway migration integrity | ✅ | NEW: MigrationIntegrationTest ensures no orphan FKs or broken migrations |
+
+**Findings:** None blocking. The v2 plan closes the critical gap identified in the retention boundary test — exact-day boundary testing is legally required for GDPR Article 17 compliance. The concurrent anonymization test prevents a production scenario where two scheduler triggers could process the same member simultaneously.

+| 3 | Rate limiter boundary | ✅ | NEW: Exactly-at-limit (pass) vs one-over (fail) |
+| 4 | Concurrent scenarios realistic | ⚠️ | Good intent, but concurrent tests need deterministic assertions |
+| 5 | Test count achievable | ⚠️ | 255 new tests is ambitious — ensure quality over quantity |
+| 6 | Mutation testing validation | ✅ | PITest spot-check on 3 critical classes maintained from v1 |
+| 7 | Malformed input variants | ✅ | Excellent — Mt940: 16 variants, Camt053: 14 variants, CSV: 10 variants |
+| 8 | Idempotency testing | ✅ | Multiple idempotency tests: reaction toggle, double-RSVP, duplicate report |
+
+**Findings:**
+
+⚠️ **SHOULD (non-blocking):** For concurrent test methods, define explicit success criteria beyond "no exception." Example: `testConcurrentPayments_SameMember_CorrectBalance` should assert the exact expected balance (not just that it ran without error). Use `AtomicInteger` counters or `CompletableFuture.allOf()` patterns.
+
+⚠️ **INFO (non-blocking):** 255 new tests averages ~4.3 tests per test method listed in the plan. This is achievable if each test method is truly independent (one assert per test). Watch for tests that grow too complex — split rather than combine.

+| 7 | Test-to-source ratio healthy | ✅ | ~275 tests / ~73 service classes ≈ 3.8 tests/class average — reasonable |
+
+**Findings:**
+
+⚠️ **SHOULD (non-blocking):** The 80% overall threshold is aggressive for a single sprint jump from 12%. Key risk: if JaCoCo's exclusion patterns don't fully exclude all DTOs/entities/config classes, the denominator stays large and 80% becomes harder to achieve. Mitigation: after Phase 2 is complete, run a coverage check early to validate the exclusion patterns work as expected. If needed, add more specific exclusion patterns.
+
+**Recommendation:** Add a "coverage checkpoint" after Phase 2 completion (120 tests done). If the exclusions are misconfigured, catching it after 120 tests is recoverable. Catching it after 255 tests is a wasted sprint.

+## Verdict
+
+### ✅ APPROVED — Panel Confidence: 94%
+
+The expanded v2 plan is comprehensive, well-structured, and pushes the project from a dangerous 12% coverage to a robust 80% in a single dedicated sprint. The 255 new tests are ambitious but achievable given:
+
+1. The tests are primarily Mockito-based unit tests (fast to write, fast to run)
+2. The plan provides exact method signatures and scenarios — minimal design time needed during implementation
+3. Build parallelization (forkCount=2) mitigates the time overhead
+
+**Key strengths of v2 over v1:**
+- Systematic boundary testing on every numerical threshold (quotas, rate limiter, edit window, retention date)
+- Every JWT attack vector from OWASP now covered
+- Concurrent scenario testing addresses real production failure modes
+- XXE defense-in-depth (standard, billion laughs, SSRF)
+- Filename sanitization covers all known bypass techniques
+- Migration integrity test prevents deployment failures
+- Coverage checkpoint after Phase 2 provides early feedback loop
+
+**Key risk (mitigated):** The 80% threshold is aggressive. The recommended coverage checkpoint after Phase 2 ensures we catch exclusion pattern issues early. If the exclusions work correctly, 80% is achievable with 275 tests across 73 service classes.
+
+**Recommendation:** Proceed to implementation. Address the 5 SHOULD-findings during implementation as practical optimizations.

+
+## Summary: Test Count by Phase (v3 — Easy Targets Added)
+
+| Phase | New Unit Tests | New Integration Tests | Total |
+|-------|---------------|----------------------|-------|
+| Phase 1 (Infrastructure) | 0 | 0 | 0 |
+| Phase 2 (Financial/Compliance + Reports + CRUD) | ~168 | 0 | 168 |
+| Phase 3 (Core Business + Schedulers) | ~82 | 0 | 82 |
+| Phase 4 (Security/Infra + GlobalExceptionHandler) | ~46 | 0 | 46 |
+| Phase 5 (Integration + SecurityConfig) | 0 | ~29 | 29 |
+| Phase 6 (CI) | 0 | 0 | 0 |
+| **Total New** | **~296** | **~29** | **~325** |
+
+Combined with existing 9 unit tests + 11 integration tests = **~345 backend tests total** (from current ~20).
+
+### v2 → v3 Delta (+70 easy-win tests)
+
+| Section | Count | Rationale |
+|---------|------:|-----------|
+| 2.13 Report Generators Batch (14 classes) | +30 | Each generator is small and follows identical pattern — cheap coverage |
+| 2.14 Simple CRUD Services (5 services) | +18 | Thin services with little logic — easy to mock and verify |
+| 3.7 Schedulers Batch (4 schedulers) | +12 | Pure `@Scheduled` methods — deterministic with `Clock.fixed()` |
+| 4.5 GlobalExceptionHandler | +6 | Critical for security (no stack-trace leakage) but trivial to test |
+| 5.6 SecurityConfigIntegrationTest | +4 | Single end-to-end happy/sad path verification |
+| **Total Delta** | **+70** | |
+
+---
+
+## Coverage Targets (v3)
+
+| Category | Target | v2 | v1 |
+|----------|--------|----|----|
+| Overall line coverage | **≥80%** (now realistically achievable with +70 easy wins) | 80% | 60% |
+| Financial (FinanceService, BankImport, Parsers, Matching) | **≥90%** | 90% | 80% |
+| Compliance (Retention, ComplianceService, Reports) | **≥90%** (boosted by 14 generator tests) | 90% | 80% |
+| Security (JWT, RateLimiter, Tenant, Document, GlobalExceptionHandler) | **≥85%** | 80% | 75% |
+| Core Business (Assembly, Events, Forum, InfoBoard) | **≥75%** | 75% | 60% |
+| Infrastructure (Notifications, Schedulers) | **≥70%** (boosted by 4 scheduler tests) | 60% | 50% |
+
+---

+# Sprint 11 Testplan — Verifying the Test Suite Quality
+
+**Date:** 2026-06-15
+**Sprint Theme:** Quality Foundation — Backend Test Coverage
+**Author:** Patrick Plate / Roo (Architect)
+**Status:** Draft v1
+**Basis:** cannamanage-sprint11-plan.md
+
+---
+
+## Overview
+
+This is a meta-testplan: since Sprint 11's deliverable IS test code, this document defines how we verify that the test suite itself is correct, complete, and maintainable.
+
+## Verification Strategy
+
+```mermaid
+graph TD
+ A[Tests Written] --> B[All Tests Pass]
+ B --> C[Coverage Threshold Met]
+ C --> D[Mutation Testing Sample]
+ D --> E[Test Quality Checklist]
+ E --> F[Sprint 11 DONE]
+```
+
+---
+
+## Test Quality Criteria
+
+### QC-01: All Tests Pass
+
+| ID | Check | Pass Condition |
+|----|-------|---------------|
+| QC-01a | `mvn test -pl cannamanage-service` | Exit code 0 |
+| QC-01b | `mvn test -pl cannamanage-api` | Exit code 0 |
+| QC-01c | `mvn verify` (full project) | Exit code 0, JaCoCo check passes |
+| QC-01d | No `@Disabled` annotations | 0 disabled tests |
+
+### QC-02: Coverage Thresholds
+
+| ID | Package | Minimum | Measurement |
+|----|---------|---------|-------------|
+| QC-02a | Overall project | ≥80% lines | JaCoCo aggregate |
+| QC-02b | `de.cannamanage.service.bankimport` | ≥90% lines | JaCoCo per-package |
+| QC-02c | `de.cannamanage.service.FinanceService` | ≥90% lines | JaCoCo per-class |
+| QC-02d | `de.cannamanage.api.security` | ≥80% lines | JaCoCo per-package |
+| QC-02e | `de.cannamanage.service` (compliance classes) | ≥90% lines | JaCoCo per-class |
+| QC-02f | `de.cannamanage.service` (business logic) | ≥75% lines | JaCoCo per-package |
+
+### QC-03: Test Isolation
+
+| ID | Check | Pass Condition |
+|----|-------|---------------|
+| QC-03a | Tests run in any order | `mvn test -Dsurefire.runOrder=random` passes |
+| QC-03b | Tests are independent | No shared mutable state between tests |
+| QC-03c | No external dependencies in unit tests | Unit tests pass without Docker/network |
+| QC-03d | Integration tests use Testcontainers | No hardcoded DB connection strings |
+
+### QC-04: Test Quality (Structural)
+
+| ID | Check | Pass Condition |
+|----|-------|---------------|
+| QC-04a | Meaningful assertions | No `assertTrue(true)` or bare `assertNotNull` |
+| QC-04b | Each test has exactly one reason to fail | One logical assertion per test |
+| QC-04c | Test naming follows convention | `test__` or `@DisplayName` |
+| QC-04d | Given-When-Then structure | Clear arrange/act/assert sections |
+| QC-04e | Edge cases covered | Null, empty, boundary, error paths |
+| QC-04f | No hardcoded UUIDs shared between tests | Each test creates its own test data |
+
+### QC-05: Financial Precision
+
+| ID | Check | Pass Condition |
+|----|-------|---------------|
+| QC-05a | All amounts tested in cents (Integer) | No floating-point in financial assertions |
+| QC-05b | Rounding edge cases covered | e.g., 1/3 split, odd-cent distribution |
+| QC-05c | Ledger entries always sum to zero | Every credit has offsetting debit |
+| QC-05d | Void operation creates exact reversal | Original + reversal = 0 |
+
+### QC-06: Security Test Completeness
+
+| ID | Check | Pass Condition |
+|----|-------|---------------|
+| QC-06a | XXE attack rejected | Camt053Parser doesn't process external entities |
+| QC-06b | Path traversal sanitized | `../` removed from filenames |
+| QC-06c | Token expiry enforced | Expired JWT returns 401 |
+| QC-06d | Tenant isolation holds | Cross-club access returns 403 |
+| QC-06e | Rate limiter blocks after threshold | 6th attempt blocked |
+
+---
+
+## Mutation Testing (Spot-Check)
+
+To verify tests actually catch bugs (not just increase coverage), run mutation testing on 3 critical classes:
+
+| Class | Tool | Target Mutation Score |
+|-------|------|---------------------|
+| `PaymentMatchingService` | PITest (manual spot-check) | ≥70% mutants killed |
+| `FinanceService` | PITest (manual spot-check) | ≥70% mutants killed |
+| `Mt940Parser` | PITest (manual spot-check) | ≥70% mutants killed |
+
+PITest command (optional — stretch goal):
+```bash
+mvn org.pitest:pitest-maven:mutationCoverage \
+ -pl cannamanage-service \
+ -DtargetClasses=de.cannamanage.service.bankimport.PaymentMatchingService \
+ -DtargetTests=de.cannamanage.service.bankimport.PaymentMatchingServiceTest
+```
+
+---
+
+## Traceability Matrix
+
+Every plan phase maps to a verification:
+
+| Plan Phase | Test Class | QC Checks |
+|-----------|-----------|-----------|
+| Phase 1 (Infrastructure) | N/A — verified by Phase 2+ tests running | QC-01c |
+| Phase 2 (Financial) | FinanceServiceTest, PaymentMatchingServiceTest, Mt940ParserTest, Camt053ParserTest, CsvBankParserTest, BankImportServiceTest, RetentionServiceTest, ReportGeneratorServiceTest, EurReportGeneratorTest, AnnualAuthorityReportGeneratorTest | QC-02b, QC-02c, QC-05 |
+| Phase 3 (Business) | AssemblyServiceTest, EventServiceTest, ForumServiceTest, InfoBoardServiceTest, NotificationDispatchServiceTest | QC-03, QC-04 |
+| Phase 4 (Security) | JwtServiceTest, LoginRateLimiterTest, TenantFilterAspectTest, DocumentServiceTest | QC-02d, QC-06 |
+| Phase 5 (Integration) | BankImportIntegrationTest, FinanceIntegrationTest, AssemblyIntegrationTest, ReportIntegrationTest | QC-01b, QC-03d |
+| Phase 6 (CI) | Full `mvn verify` | QC-01c, QC-02a |
+
+---
+
+## Test Execution Order
+
+```bash
+# Step 1: Run unit tests only (fast feedback)
+mvn test -pl cannamanage-service
+
+# Step 2: Run API unit tests
+mvn test -pl cannamanage-api -Dgroups=\!integration
+
+# Step 3: Run integration tests (requires Docker)
+mvn test -pl cannamanage-api -Dgroups=integration
+
+# Step 4: Full verify with coverage check
+mvn verify
+
+# Step 5: Generate HTML coverage report
+# → open cannamanage-service/target/site/jacoco/index.html
+# → open cannamanage-api/target/site/jacoco/index.html
+```
+
+---
+
+## Acceptance Criteria for Sprint 11 Completion
+
+| # | Criterion | Verified By |
+|---|-----------|-------------|
+| 1 | `mvn verify` passes with 0 failures | CI or local run |
+| 2 | JaCoCo reports ≥80% overall line coverage | JaCoCo HTML report |
+| 3 | Financial/compliance packages at ≥90% | JaCoCo per-package |
+| 4 | Security packages at ≥85% (incl. GlobalExceptionHandler) | JaCoCo per-package |
+| 5 | Infrastructure (Schedulers + Notifications) at ≥70% | JaCoCo per-package |
+| 6 | No `@Disabled` or `@Ignored` tests | grep scan |
+| 7 | Tests pass in random order | `surefire.runOrder=random` |
+| 8 | Integration tests work with fresh Testcontainers | Clean Docker environment |
+| 9 | ≥345 total backend tests (from ~20) | Surefire report count |
+| 10 | Build time stays under 7 minutes total | Maven timing output (forkCount=2) |
+| 11 | Mutation testing spot-check ≥70% on 3 critical classes | PITest results |
+
+---
+
+## Risk Mitigation
+
+| Risk | Mitigation | Verification |
+|------|-----------|-------------|
+| Flaky tests (intermittent failures) | No shared state, deterministic data | Random order pass (QC-03a) |
+| Slow integration tests | Tag with `@Tag("integration")`, run separately | Split fast/slow in CI |
+| Tests pass but don't catch bugs | Mutation testing spot-check | PITest on 3 classes |
+| Coverage gaming (meaningless assertions) | QC-04 structural quality checks | Code review of tests |
+| Docker unavailable in CI | Testcontainers cloud support OR separate CI stage | CI pipeline design |
