Test-driven development for Quarkus 3.x LTS using JUnit 5, Mockito, REST Assured, Camel testing, and JaCoCo. Use when adding features, fixing bugs, or refactoring event-driven services.

僅含說明Software Development
AI 產生的概覽

指導 Quarkus 3.x 服務的測試驅動開發，使用 JUnit 5、Mockito、REST Assured、Camel 測試與 JaCoCo。

功能
此技能為 Quarkus 3.x 服務提供 TDD 工作流程：先撰寫會失敗的測試，再實作最小可用程式碼，在測試通過後重構，並以 JaCoCo 強制達到 80% 以上覆蓋率。它提供多個完整範例，涵蓋以 @Nested 組織並搭配 Mockito 模擬的單元測試、使用 AdviceWith 與 MockEndpoint 的 Camel 路由測試、事件服務測試、CompletableFuture 與 LogContext 傳遞測試、REST Assured 資源層測試，以及連接真實資料庫的整合測試。它也列出所需的 Maven 測試相依套件與 JaCoCo 外掛設定。
適用情境
適用於新增功能或 REST 端點、修正錯誤或重構 Quarkus 服務時，尤其是採用 Apache Camel、RabbitMQ、反應式串流或非同步 CompletableFuture 作業的事件驅動服務。也適合新增資料存取邏輯、安全規則或條件流程邏輯且需要測試覆蓋的情況。
執行需求
需要一個 Quarkus 3.x LTS 的 Java 專案，使用 Maven，並包含測試相依套件：quarkus-junit5、quarkus-junit5-mockito、mockito-core、assertj-core、rest-assured、camel-quarkus-junit5，以及用於覆蓋率的 JaCoCo。不附帶指令碼，僅為說明文件與程式碼範例。

Quarkus TDD Workflow

TDD guidance for Quarkus 3.x services with 80%+ coverage (unit + integration). Optimized for event-driven architectures with Apache Camel.

When to Use

  • New features or REST endpoints
  • Bug fixes or refactors
  • Adding data access logic, security rules, or reactive streams
  • Testing Apache Camel routes and event handlers
  • Testing event-driven services with RabbitMQ
  • Testing conditional flow logic
  • Validating CompletableFuture async operations
  • Testing LogContext propagation

Workflow

  1. Write tests first (they should fail)
  2. Implement minimal code to pass
  3. Refactor with tests green
  4. Enforce coverage with JaCoCo (80%+ target)

Unit Tests with @Nested Organization

Follow this structured approach for comprehensive, readable tests:

java
@ExtendWith(MockitoExtension.class)@DisplayName("OrderService Unit Tests")class OrderServiceTest {
  @Mock  private OrderRepository orderRepository;
  @Mock  private EventService eventService;
  @Mock  private FulfillmentPublisher fulfillmentPublisher;
  @InjectMocks  private OrderService orderService;
  private CreateOrderCommand validCommand;
  @BeforeEach  void setUp() {    validCommand = new CreateOrderCommand(        "customer-123",        List.of(new OrderLine("sku-123", 2))    );  }
  @Nested  @DisplayName("Tests for createOrder")  class CreateOrder {
    @Test    @DisplayName("Should persist order and publish fulfillment event")    void givenValidCommand_whenCreateOrder_thenPersistsAndPublishes() {      // ARRANGE      doNothing().when(orderRepository).persist(any(Order.class));
      // ACT      OrderReceipt receipt = orderService.createOrder(validCommand);
      // ASSERT      assertThat(receipt).isNotNull();      assertThat(receipt.customerId()).isEqualTo("customer-123");      verify(orderRepository).persist(any(Order.class));      verify(fulfillmentPublisher).publishAsync(receipt);      verify(eventService).createSuccessEvent(receipt, "ORDER_CREATED");    }
    @Test    @DisplayName("Should reject missing customer id")    void givenMissingCustomerId_whenCreateOrder_thenThrowsBadRequest() {      // ARRANGE      CreateOrderCommand invalid = new CreateOrderCommand("", validCommand.lines());
      // ACT & ASSERT      WebApplicationException exception = assertThrows(          WebApplicationException.class,          () -> orderService.createOrder(invalid)      );
      assertThat(exception.getResponse().getStatus()).isEqualTo(400);      verify(orderRepository, never()).persist(any(Order.class));      verify(fulfillmentPublisher, never()).publishAsync(any());    }
    @Test    @DisplayName("Should record error event when persistence fails")    void givenPersistenceFailure_whenCreateOrder_thenRecordsErrorEvent() {      // ARRANGE      doThrow(new PersistenceException("database unavailable"))          .when(orderRepository).persist(any(Order.class));
      // ACT & ASSERT      PersistenceException exception = assertThrows(          PersistenceException.class,          () -> orderService.createOrder(validCommand)      );
      assertThat(exception.getMessage()).contains("database unavailable");      verify(eventService).createErrorEvent(          eq(validCommand),          eq("ORDER_CREATE_FAILED"),          contains("database unavailable")      );      verify(fulfillmentPublisher, never()).publishAsync(any());    }
    @Test    @DisplayName("Should reject null commands")    void givenNullCommand_whenCreateOrder_thenThrowsNullPointerException() {      // ACT & ASSERT      assertThrows(          NullPointerException.class,          () -> orderService.createOrder(null)      );
      verify(orderRepository, never()).persist(any(Order.class));    }  }}

Key Testing Patterns

  1. @Nested Classes: Group tests by method being tested
  2. @DisplayName: Provide readable test descriptions for test reports
  3. Naming Convention: givenX_whenY_thenZ for clarity
  4. AAA Pattern: Explicit // ARRANGE, // ACT, // ASSERT comments
  5. @BeforeEach: Setup common test data to reduce duplication
  6. assertDoesNotThrow: Test success scenarios without catching exceptions
  7. assertThrows: Test exception scenarios with message validation using AssertJ
  8. Comprehensive Coverage: Test happy paths, null inputs, edge cases, exceptions
  9. Verify Interactions: Use Mockito verify() to ensure methods are called correctly
  10. Never Verify: Use never() to ensure methods are NOT called in error scenarios

Best Practices

Test Organization

  • Use @Nested classes to group tests by method being tested
  • Use @DisplayName for readable test descriptions visible in reports
  • Follow givenX_whenY_thenZ naming convention for test methods
  • Use @BeforeEach for common test data setup to reduce duplication

Test Structure

  • Follow AAA pattern with explicit comments (// ARRANGE, // ACT, // ASSERT)
  • Use assertDoesNotThrow for success scenarios
  • Use assertThrows for exception scenarios with message validation
  • Verify exception messages match expected values using AssertJ contains() or isEqualTo()

Test Coverage

  • Test happy paths for all public methods
  • Test null input handling
  • Test edge cases (empty collections, boundary values, negative IDs, blank strings)
  • Test exception scenarios comprehensively
  • Mock all external dependencies (repositories, services, Camel endpoints)
  • Aim for 80%+ line coverage, 70%+ branch coverage

Assertions

  • Prefer AssertJ (assertThat) over JUnit assertions for value checks
  • Use fluent AssertJ API for readability: assertThat(list).hasSize(3).contains(item)
  • For exceptions: use JUnit assertThrows to capture, then AssertJ to validate the message
  • For non-throwing success paths: use JUnit assertDoesNotThrow
  • For collections: extracting(), filteredOn(), containsExactly()

Testing Integration

  • Use @QuarkusTest for integration tests
  • Use @InjectMock to mock dependencies in Quarkus tests
  • Prefer REST Assured for API testing
  • Use @TestProfile for test-specific configuration

Event-Driven Testing

  • Test Camel routes with AdviceWith and MockEndpoint
  • Use @CamelQuarkusTest annotation (if using standalone Camel tests)
  • Verify message content, headers, and routing logic
  • Test error handling routes separately
  • Mock external systems (RabbitMQ, S3, databases) in unit tests

Camel Route Testing

  • Use MockEndpoint for asserting message flow
  • Use AdviceWith to modify routes for testing (replace endpoints with mocks)
  • Test message transformation and marshalling
  • Test exception handling and dead letter queues

Testing Async Operations

  • Test CompletableFuture success and failure scenarios
  • Use .join() in tests to wait for async completion
  • Test exception propagation from CompletableFuture
  • Verify LogContext propagation to async operations

Performance

  • Keep tests fast and isolated
  • Run tests in continuous mode: mvn quarkus:test
  • Use parameterized tests (@ParameterizedTest) for input variations
  • Build reusable test data builders or factory methods

Quarkus-Specific

  • Stay on latest LTS version (Quarkus 3.x)
  • Test native compilation compatibility periodically
  • Use Quarkus test profiles for different scenarios
  • Leverage Quarkus dev services for local testing
  • Use @InjectMock instead of @MockBean (Quarkus-specific)

Verification Best Practices

  • Always verify interactions on mocked dependencies
  • Use verify(mock, never()) to ensure methods are NOT called in error scenarios
  • Use argThat() for complex argument matching
  • Verify the order of calls when it matters: InOrder from Mockito
