Добавить Spring 3.0.0 Java на основе МОК JUnit 4.7 тесты

Question

Там является документ http://static.springsource.org/spring/docs/2.5.6/reference/testing.html, как добавить поддержку IoC в JUnit тестов с использованием XML-конфигурации, но я не могу найти пример конфигурации Java на основе ...

Например, я Java на основе боба:

public class AppConfig 
{ 
    @Bean 
    public Test getTest() { return new Test(); } 
} 

И тест:

@RunWith(SpringJUnit4ClassRunner.class) 
public class IocTest 
{ 
    @Autowired 
    private Test test; 

    @Test 
    public void testIoc() 
    { 
     Assert.assertNotNull(test); 
    } 
} 

Что я должен добавить, чтобы включить Java на основе бобов на мой JUnit тест без использования XML-конфиги?

Обычно я использую:

new AnnotationConfigApplicationContext(AppConfig.class); 

, но он не работает для испытаний ...

Answer 1

Обновление: Весна 3.1 будет поддерживать ее из коробки, см. Spring 3.1 M2: Testing with @Configuration Classes and Profiles.

---

Кажется, что эта функция еще не поддерживается весной. Однако, это может быть легко реализовано:

public class AnnotationConfigContextLoader implements ContextLoader { 

    public ApplicationContext loadContext(String... locations) throws Exception { 
     Class<?>[] configClasses = new Class<?>[locations.length]; 
     for (int i = 0; i < locations.length; i++) { 
      configClasses[i] = Class.forName(locations[i]); 
     }   
     return new AnnotationConfigApplicationContext(configClasses); 
    } 

    public String[] processLocations(Class<?> c, String... locations) { 
     return locations; 
    } 
} 

-

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, 
    value = "com.sample.AppConfig") 
public class IocTest { 
    @Autowired 
    TestSerivce service; 

    @Test 
    public void testIoc() 
    { 
     Assert.assertNotNull(service.getPredicate()); 
    } 
} 

-

@Configuration 
public class ApplicationConfig 
{ 
    ... 

    @Bean 
    public NotExistsPredicate getNotExistsPredicate() 
    { 
     return new NotExistsPredicate(); 
    } 

    @Bean 
    public TestService getTestService() { 
     return new TestService(); 
    } 
}

Если вы получаете нулевое значение, вероятно, это не нагружает контекст приложения.

Обратите внимание, что по умолчанию бегун загружает его из «путь к классам: /com/test/IocTest-context.xml» (предполагается, что пакет IocTest.java является com.test)

Если нет попробовать указав его, добавив

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { "PATH_TO_YOUR_APP_CONTEXT/yourApplicationContext.xml" }) 
public class IocTest 
{ 
    @Autowired 
    private Test test; 

    @Test 
    public void testIoc() 
    { 
     Assert.notNull("test is null", test); 
    } 
} 

Answer 3

Genereally, почему это не работает (утверждают сбой): выход

public class IocTest 
{ 
    @BeforeClass 
    public static void initSpringIoc() 
    { 
     AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(ApplicationConfig.class); 
     NotExistsPredicate predicate = ctx.getBean(NotExistsPredicate.class); 
     LoggerFactory.getLogger(IocTest.class).debug(predicate.toString()); 
    } 

    @Test 
    public void testIoc() 
    { 
     TestService service = new TestService(); 
     Assert.assertNotNull(service.getPredicate()); // assert fails 
    } 
} 

public class TestService 
{ 
    @Autowired 
    private NotExistsPredicate predicate; 

    public NotExistsPredicate getPredicate() 
    { 
     return predicate; 
    } 
}
