CPS-1379: Create CpsPersistenceSpecBase2Closed

Description

Currently, data is inserted into the database for persistence testing by using SQL scripts. This led to data which cannot conform to any yang model being used for testing purposes. Therefore we want to insert data by using service layer methods. This includes inserting a yang model and data which conforms to it.

Issues & Decisions

	Issue	Notes	Decision

	Issue	Notes	Decision
1	1	Insert data using Service Layer Methods	Validates data with minimal test performance impact if it works	Primary solution
2	Insert data using a cps container with test containers	Validates data but can have a bigger performance hit. Also issues relating to which image is used for the image that is spun up	Possible secondary solution
3	Insert data using liquibase	No data validation but will be hopefully easier to read. Also cannot add more data/reset data during testing	Not sure if it's worth it, will be similar to the current implementation unless the data can be inserted in json format somehow

Using Service Layer Methods

https://gerrit.nordix.org/c/onap/cps/+/16357/3 (Patchset 3)

CpsPersistenceSpecBase2.groovy

Since this SpringBootTest does not have the scope of the service layer included, we need to manually tell spring where to find the beans when the test is run. This is done through an inner class with the Configuration annotation and ComponentScan for the relevant modules. The Autowired annotation catches the beans for the other layers and then the Bean annotated methods bring the beans to the outer test class. There are issues with bean instantiation order in this test hence why the Lazy annotation is also included.

Configuration Inner Class

@ComponentScan("org.onap.cps.api,org.onap.cps.spi,org.onap.cps.spi.repository,org.onap.cps.notification")
    @Configuration
//    @ContextConfiguration(classes = [KafkaAutoConfiguration, KafkaProducerListener, NotificationErrorHandler])
    static class TestConfig {
        @Autowired
        @Lazy
        CpsAdminService cpsAdminService

        @Autowired
        @Lazy
        DataspaceRepository dataspaceRepository

        @Autowired
        @Lazy
        AnchorRepository anchorRepository

        @Autowired
        @Lazy
        FragmentRepository fragmentRepository
//
//        @Autowired
//        @Lazy
//        NotificationService notificationService
//
        @Autowired
        @Lazy
        YangResourceRepository yangResourceRepository

        @Autowired
        @Lazy
        SchemaSetRepository schemaSetRepository

        @Autowired
        @Lazy
        ModuleReferenceRepository moduleReferenceRepository

        @Autowired
        @Lazy
        EntityManagerFactory entityManagerFactory
//
//        @Autowired
//        @Lazy
//        KafkaTemplate kafkaTemplate
//
//        @Bean
//        CpsAdminService cpsAdminService() {
//            cpsAdminService
//            return cpsAdminService
//        }
//
        @Bean
        DataspaceRepository dataspaceRepository() {
            return dataspaceRepository
        }

        @Bean
        AnchorRepository anchorRepository() {
            return anchorRepository
        }

        @Bean
        FragmentRepository fragmentRepository() {
            return fragmentRepository
        }

        @Bean
        YangResourceRepository yangResourceRepository() {
            return yangResourceRepository
        }

        @Bean
        SchemaSetRepository schemaSetRepository() {
            return schemaSetRepository
        }

        @Bean
        ModuleReferenceRepository moduleReferenceRepository() {
            return moduleReferenceRepository
        }

        @Bean
        EntityManagerFactory entityManagerFactory() {
            return entityManagerFactory
        }
    }

Currently this test results in an ambiguous stackoverflow error which I reckon is due to two beans being created at the same time. Tried renaming the beans and it doesn't seem to have an effect.

Using CPS Container

https://gerrit.nordix.org/c/onap/cps/+/16357/4 (Patchset 4)

Using an image of CPS we can insert the data for the tests. We already use a testcontainer for the postgres used. Currently testcontainers is trying to pull docker from nordix which is resulting in an error for this implementation.

Docker Error
