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
