[SOLVED] Spring Modulith - ApplicationModuleTest with JPA repositories in different modules

While working with Spring Modulith I am trying to test the ApplicationModuleTest in a multi module application. I am running into problems when spring is trying to create JpaRepositories implementations for modules that are not under test.

My project structure is as follows:

nl.daniel.dejong

Application.java

inventorymanagement

domain

ProductService.java

Product.java

ProductId.java

infrastructure.persistence

ProductJpaPersistence.java

orderfulfillment

domain

OutboundOrder.java

infrastructure.persistence

OutboundOrderJpaPersistence.java

The persistences are default JpaPersistences using the domain object as domain object eg:

@Repository
public interface ProductJpaPersistence extends ProductPersistence, JpaRepository<Product, ProductId> {
}

My Application.java looks as follows

@SpringBootApplication
@EnableAsync
@ConfigurationPropertiesScan
@EnableJpaRepositories
public class Application {
    public static void main(String... args) {
        SpringApplication.run(Application.class, args);
    }
}

When creating a ApplicationModuleTest for the product module It is trying to create a OutboundOrderJpaPersistence bean. The results into the problem that the ApplicationModuleTest annotation filters the scope of the test and therefor it cannot find the OutboundOrder that the Repository is managing.

Test:

@ApplicationModuleTest
@RequiredArgsConstructor
class ProductIntegrationTest {
    private static final String PRODUCT_NAME = "Product 1";
    private final ProductService productService;

    @Test
    public void createProduct(Scenario scenario) {
        var createProduct = new Product();
        createProduct.setName(PRODUCT_NAME);

        scenario.stimulate(() -> productService.create(createProduct))
                .andWaitForEventOfType(ProductCreated.class)
                .matchingMappedValue(ProductCreated::name, PRODUCT_NAME);

    }
}

StackTrace:

When changing the @EnableJpaRepositories to point to the module under test @EnableJpaRepositories("nl.daniel.dejong.inventorymanagement") the test works as expected.

PS: The situation described above is a representation as close as possible to the full implementation, but it could miss some information. Left out some of the details to not cloud the post.

Am I doing something wrong here or is this unexpected behavior?

Edit: by actually removing the ‘EnableJpaRepositories’ from the ‘Application.Java’ I am able to override the repository locations by using a configuration containing ‘EnableJpaRepositories’ in the test. I am still of opinion that SpringModulith should have a way of doing this by itself.
