Ecc Quarkus Verification

Quarkus Verification Loop

Run before PRs, after major changes, and pre-deploy.

When to Activate

• Before opening a pull request for a Quarkus service
• After major refactoring or dependency upgrades
• Pre-deployment verification for staging or production
• Running full build → lint → test → security scan → native compilation pipeline
• Validating test coverage meets thresholds (80%+)
• Testing native image compatibility

Phase 1: Build

# Maven
mvn clean verify -DskipTests

# Gradle
./gradlew clean assemble -x test

If build fails, stop and fix compilation errors.

Phase 2: Static Analysis

Checkstyle, PMD, SpotBugs (Maven)

mvn checkstyle:check pmd:check spotbugs:check

SonarQube (if configured)

mvn sonar:sonar \
  -Dsonar.projectKey=my-quarkus-project \
  -Dsonar.host.url=http://localhost:9000 \
  -Dsonar.login=${SONAR_TOKEN}

Common Issues to Address

• Unused imports or variables
• Complex methods (high cyclomatic complexity)
• Potential null pointer dereferences
• Security issues flagged by SpotBugs

Phase 3: Tests + Coverage

# Run all tests
mvn clean test

# Generate coverage report
mvn jacoco:report

# Enforce coverage threshold (80%)
mvn jacoco:check

# Or with Gradle
./gradlew test jacocoTestReport jacocoTestCoverageVerification

Test Categories

Unit Tests

Test service logic with mocked dependencies:

@ExtendWith(MockitoExtension.class)
class UserServiceTest {
  @Mock UserRepository userRepository;
  @InjectMocks UserService userService;

  @Test
  void createUser_validInput_returnsUser() {
    var dto = new CreateUserDto("Alice", "alice@example.com");

    // Panache persist() is void — use doNothing + verify
    doNothing().when(userRepository).persist(any(User.class));

    User result = userService.create(dto);

    assertThat(result.name).isEqualTo("Alice");
    verify(userRepository).persist(any(User.class));
  }
}

Integration Tests

Test with real database (Testcontainers):

@QuarkusTest
@QuarkusTestResource(PostgresTestResource.class)
class UserRepositoryIntegrationTest {

  @Inject
  UserRepository userRepository;

  @Test
  @Transactional
  void findByEmail_existingUser_returnsUser() {
    User user = new User();
    user.name = "Alice";
    user.email = "alice@example.com";
    userRepository.persist(user);

    Optional<User> found = userRepository.findByEmail("alice@example.com");

    assertThat(found).isPresent();
    assertThat(found.get().name).isEqualTo("Alice");
  }
}

API Tests

Test REST endpoints with REST Assured:

@QuarkusTest
class UserResourceTest {

  @Test
  void createUser_validInput_returns201() {
    given()
        .contentType(ContentType.JSON)
        .body("""
            {"name": "Alice", "email": "alice@example.com"}
            """)
        .when().post("/api/users")
        .then()
        .statusCode(201)
        .body("name", equalTo("Alice"));
  }

  @Test
  void createUser_invalidEmail_returns400() {
    given()
        .contentType(ContentType.JSON)
        .body("""
            {"name": "Alice", "email": "invalid"}
            """)
        .when().post("/api/users")
        .then()
        .statusCode(400);
  }
}

Coverage Report

Check target/site/jacoco/index.html for detailed coverage:

• Overall line coverage (target: 80%+)
• Branch coverage (target: 70%+)
• Identify uncovered critical paths

Phase 4: Security Scanning

Dependency Vulnerabilities (Maven)

mvn org.owasp:dependency-check-maven:check

Review target/dependency-check-report.html for CVEs.

Quarkus Security Audit

# Check vulnerable extensions
mvn quarkus:audit

# List all extensions
mvn quarkus:list-extensions

OWASP ZAP (API Security Testing)

docker run -t owasp/zap2docker-stable zap-api-scan.py \
  -t http://localhost:8080/q/openapi \
  -f openapi

Common Security Checks

• All secrets in environment variables (not in code)
• Input validation on all endpoints
• Authentication/authorization configured
• CORS properly configured
• Security headers set
• Passwords hashed with BCrypt
• SQL injection protection (parameterized queries)
• Rate limiting on public endpoints

Phase 5: Native Compilation

Test GraalVM native image compatibility:

# Build native executable
mvn package -Dnative

# Or with container
mvn package -Dnative -Dquarkus.native.container-build=true

# Test native executable
./target/*-runner

# Run basic smoke tests
curl http://localhost:8080/q/health/live
curl http://localhost:8080/q/health/ready

Native Image Troubleshooting

Common issues:

• Reflection: Add reflection config for dynamic classes
• Resources: Include resources with quarkus.native.resources.includes
• JNI: Register JNI classes if using native libraries

Example reflection config:

@RegisterForReflection(targets = {MyDynamicClass.class})
public class ReflectionConfiguration {}

Phase 6: Performance Testing

Load Testing with K6

// load-test.js
import http from 'k6/http';
import { check } from 'k6';

export const options = {
  stages: [
    { duration: '30s', target: 50 },
    { duration: '1m', target: 100 },
    { duration: '30s', target: 0 },
  ],
};

export default function () {
  const res = http.get('http://localhost:8080/api/markets');
  check(res, {
    'status is 200': (r) => r.status === 200,
    'response time < 200ms': (r) => r.timings.duration < 200,
  });
}

Run:

k6 run load-test.js

Metrics to Monitor

• Response time (p50, p95, p99)
• Throughput (requests/sec)
• Error rate
• Memory usage
• CPU usage

Phase 7: Health Checks

# Liveness
curl http://localhost:8080/q/health/live

# Readiness
curl http://localhost:8080/q/health/ready

# All health checks
curl http://localhost:8080/q/health

# Metrics (if enabled)
curl http://localhost:8080/q/metrics

Expected responses:

{
  "status": "UP",
  "checks": [
    {
      "name": "Database connection",
      "status": "UP"
    }
  ]
}

Phase 8: Container Image Build

# Build container image
mvn package -Dquarkus.container-image.build=true

# Or with specific registry
mvn package \
  -Dquarkus.container-image.build=true \
  -Dquarkus.container-image.registry=docker.io \
  -Dquarkus.container-image.group=myorg \
  -Dquarkus.container-image.tag=1.0.0

# Test container
docker run -p 8080:8080 myorg/my-quarkus-app:1.0.0

Container Security Scan

# Trivy
trivy image myorg/my-quarkus-app:1.0.0

# Grype
grype myorg/my-quarkus-app:1.0.0

Phase 9: Configuration Validation

# Check all configuration properties
mvn quarkus:info

# List all config sources
curl http://localhost:8080/q/dev/io.quarkus.quarkus-vertx-http/config

Environment-Specific Checks

• Database URLs configured per environment
• Secrets externalized (Vault, env vars)
• Logging levels appropriate
• CORS origins set correctly
• Rate limiting configured
• Monitoring/tracing enabled

Phase 10: Documentation Review

• OpenAPI/Swagger docs up to date (/q/swagger-ui)
• README has setup instructions
• API changes documented
• Migration guide for breaking changes
• Configuration properties documented

Generate OpenAPI spec:

curl http://localhost:8080/q/openapi -o openapi.json
