quarkus-tdd applies TDD with JUnit 5, REST Assured, Camel tests, and JaCoCo on Quarkus 3.x.

About

The quarkus-tdd skill guides test-driven development for Quarkus 3.x LTS services targeting eighty percent plus unit and integration coverage with JUnit 5, Mockito, REST Assured, Apache Camel tests, and JaCoCo reporting. Workflow is red-green-refactor: write failing tests first, implement minimal code, refactor with green suite. Covers REST endpoints, data access, security rules, reactive streams, Camel routes, RabbitMQ event handlers, conditional flows, CompletableFuture async ops, and LogContext propagation. Unit tests use @Nested organization and MockitoExtension; integration tests leverage @QuarkusTest and REST Assured. Invoke when adding Quarkus features, fixing bugs, refactoring event-driven services, or enforcing coverage gates on Camel and messaging code paths. Red-green-refactor TDD workflow for Quarkus 3.x LTS. JUnit 5, Mockito, REST Assured, and Camel route testing. JaCoCo coverage target 80 percent plus unit and integration. @Nested unit test organization with MockitoExtension.

How do I TDD a Quarkus service with messaging and Camel routes at 80% coverage?

Practice TDD on Quarkus 3.x with JUnit 5, Mockito, REST Assured, Camel route tests, and JaCoCo 80 percent coverage.

Who is it for?

Java teams practicing TDD on event-driven Quarkus microservices.

Skip if: Non-Quarkus frameworks or manual QA checklists without automated tests.

When should I use this skill?

User adds Quarkus tests, REST Assured endpoints, or Camel route coverage.

What you get

Green test suite with JaCoCo report meeting 80% coverage on new Quarkus code.

  • JUnit 5 test suites
  • JaCoCo coverage report
  • Camel and REST Assured integration tests

By the numbers

  • Targets 80%+ unit and integration coverage with JaCoCo
  • Built for Quarkus 3.x LTS

Flujo de Trabajo TDD en Quarkus

Orientación TDD para servicios Quarkus 3.x con 80%+ de cobertura (unit + integración). Optimizado para arquitecturas orientadas a eventos con Apache Camel.

Cuándo Usar

  • Nuevas funcionalidades o endpoints REST
  • Correcciones de bugs o refactorizaciones
  • Agregar lógica de acceso a datos, reglas de seguridad o streams reactivos
  • Probar rutas Apache Camel y manejadores de eventos
  • Probar servicios orientados a eventos con RabbitMQ
  • Probar lógica de flujo condicional
  • Validar operaciones asíncronas con CompletableFuture
  • Probar propagación de LogContext

Flujo de Trabajo

1. Escribir pruebas primero (deben fallar) 2. Implementar el código mínimo para que pasen 3. Refactorizar con pruebas en verde 4. Exigir cobertura con JaCoCo (objetivo 80%+)

Buenas Prácticas

Organización de Pruebas

  • Usar clases @Nested para agrupar pruebas por método bajo prueba
  • Usar @DisplayName para descripciones legibles en reportes
  • Seguir la convención de nombres givenX_whenY_thenZ
  • Usar @BeforeEach para configuración de datos comunes

Cobertura de Pruebas

  • Probar rutas felices para todos los métodos públicos
  • Probar manejo de entradas null
  • Probar casos borde (colecciones vacías, valores de frontera)
  • Probar escenarios de excepción de forma comprensiva
  • Apuntar a 80%+ de cobertura de líneas, 70%+ de ramas

Aserciones

  • Preferir AssertJ (assertThat) sobre aserciones JUnit para verificar valores
  • Para excepciones: usar JUnit assertThrows para capturar, luego AssertJ para validar
  • Para escenarios exitosos sin excepción: usar JUnit assertDoesNotThrow

Pruebas de Integración

  • Usar @QuarkusTest para pruebas de integración
  • Usar @InjectMock para mockear dependencias en pruebas Quarkus
  • Preferir REST Assured para pruebas de API
  • Usar @TestProfile para configuración específica de prueba
