如何存根Spring存储库以在集成测试中抛出异常？

Question

我有一个服务，它有一个存储库作为构造函数的参数。

@Autowired
NodeServiceListInstallService( final BykiListRepository aBykiListRepository )

ByKilistRepository是默认的Spring存储库，没有实现

interface BykiListRepository extends JpaRepository<BykiList, Long> {
    //some magic methods
}

@SpringBootApplication
@EnableConfigurationProperties( ApplicationProperties )
@EnableJpaRepositories
@EnableTransactionManagement
@ImportResource( 'classpath:META-INF/spring/application-context.xml' )
class Application extends SpringBootServletInitializer {
    @Bean
    NodeServiceListInstallService nodeServiceListInstallService( final BykiListRepository bykiListRepository ) {
        new NodeServiceListInstallService( bykiListRepository )
    }
}

@TestConfiguration
class TestConfig {
    @Bean
    BykiListRepository bykiListRepository() {
        //return Spock's Spy/Stub or new BykiRepositoryBadImpl()
    }

@ContextConfiguration( classes = TestConfig )
class GlobalErrorHandlerIntegrationTest extends BaseFlowIntegrationTest {
    //test()
}

我在Groovy-2.4.12上编写，并使用Spock-1.1编写测试。Spring Boot 1.5.4。保留的变体是使用方面，但没有完全像我希望的那样。会非常感激你的帮助。

更新:DetachedMockFactory的用法：

配置：

class DummyConfiguration {
    private final detachedFactory = new DetachedMockFactory()
    @Bean
    @Primary
    BykiListRepository bykiListRepository() {
        detachedFactory.Mock( BykiListRepository )
    }
}

@SpringBootTest( classes = DummyConfiguration )
@Import( [DummyConfiguration] )
@ContextConfiguration( classes = DummyConfiguration )
class GlobalErrorHandlerIntegrationTest extends BaseFlowIntegrationTest {
    @Autowired
    BykiListRepository bykiListRepositoryMock
    def 'exercise error handling'() {
        given: 'the failing repository'
        bykiListRepositoryMock.save( _ ) >> {
            throw new CannotCreateTransactionException()
        }
        when: 'the message is send to rabbit'
        rabbitOperations.send( configuration.rabbitExchangeName, '', msg )
    }
}

@SpringBootTest( webEnvironment = SpringBootTest.WebEnvironment.NONE )
@ContextConfiguration( classes = Application )
class BaseFlowIntegrationTest extends AbstractIntegrationTest {...}

@Category( InboundIntegrationTest )
abstract class AbstractIntegrationTest extends Specification {...}

您可以创建test configuration，如下所示，并在调用某个函数时使用Spock记录，然后将抛出ex。当然，在测试类中使用@inject或@autowire...并执行@import([IntegrationTestMockingConfig])

@TestConfiguration
class IntegrationTestMockingConfig {

     private DetachedMockFactory factory = new DetachedMockFactory()

     @Bean
     ExternalRepository externalRepository() {
         factory.Mock(ExternalRepository)
     }
}
