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 ghcr.io/zaproxy/zaproxy: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
