## Phase 1: Test Infrastructure Setup

### 1.1 Add JaCoCo Maven Plugin

**File:** `pom.xml` (parent)

Add the JaCoCo plugin to the `<build><plugins>` section of the parent POM:

```xml
<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.12</version>
    <executions>
        <execution>
            <id>prepare-agent</id>
            <goals><goal>prepare-agent</goal></goals>
        </execution>
        <execution>

        </execution>
        <execution>
            <id>check</id>
            <phase>verify</phase>
            <goals><goal>check</goal></goals>
            <configuration>
                <rules>
                    <rule>

                                <value>COVEREDRATIO</value>
                                <minimum>0.80</minimum>
                            </limit>
                        </limits>
                    </rule>
                </rules>
            </configuration>
        </execution>
    </executions>
    <configuration>
        <excludes>
            <exclude>**/entity/**</exclude>
            <exclude>**/enums/**</exclude>
            <exclude>**/dto/**</exclude>
            <exclude>**/config/**</exclude>
            <exclude>**/CannaManageApplication.*</exclude>
        </excludes>
    </configuration>
</plugin>
```

### 1.2 Add Maven Surefire Parallelization

**File:** `pom.xml` (parent)

```xml
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <forkCount>2</forkCount>
        <reuseForks>true</reuseForks>
    </configuration>
</plugin>
```

### 1.3 Create Abstract Unit Test Base

**File:** `cannamanage-service/src/test/java/de/cannamanage/service/AbstractServiceTest.java`

```java
package de.cannamanage.service;

import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.junit.jupiter.MockitoExtension;
import java.util.UUID;

@ExtendWith(MockitoExtension.class)
public abstract class AbstractServiceTest {
    protected static final UUID TEST_CLUB_ID = UUID.fromString("aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa");
    protected static final UUID TEST_MEMBER_ID = UUID.fromString("bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb");
    protected static final UUID TEST_USER_ID = UUID.fromString("cccccccc-cccc-cccc-cccc-cccccccccccc");
    protected static final UUID TEST_STAFF_ID = UUID.fromString("dddddddd-dddd-dddd-dddd-dddddddddddd");
}
```

### 1.4 Create Test Data Fixtures

**Files:**
- `cannamanage-service/src/test/resources/bankimport/sample.mt940` — realistic MT940 file (Sparkasse format)
- `cannamanage-service/src/test/resources/bankimport/sample-real-sparkasse.mt940` — anonymized real Sparkasse statement

- `de.cannamanage.service` (finance-related) — **90% minimum**
- `de.cannamanage.api.security` — **80% minimum**
- `de.cannamanage.service.*` (business logic) — **75% minimum**

## 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% |
