Repository unit-testing on a library project

I am working on a multi module project using Spring Boot. I want to write some unit tests to check my repository, services, etc. The repositories codes is written on a common project which is used on other projects. This project doesn't contain any starter app. It's just composed of entities, repositories and services.

I saw this topic (How to test Maven module project with Spring Boot) about a similar issue but I don't manage to succeed to implement it for testing my repository.

The exception "NoSuchBeanDefinitionException" is raised for the EntityARepository (see the code below) when I launch the test : I understand that the tests can access to bean that I have created on the src/main/java folder. How can I resolve this ?

On the test folder (test/java) of this maven project, I create three files on several packages :

package com.domain.test
@SpringBootApplication()
public class ProjectCommonsTestApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProjectCommonsTestApplication.class, args);
    }
}

package com.domain.test.repository

@RunWith(SpringRunner.class)
@DataJpaTest
public class EntityARepositoryTest {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private EntityARepository entityARepository;

    @Test
    public void someUnitTest(){
        //given
        //when
        //then
    }
}

And the application.yml file, on the folder test/resources

spring:
  application:
    name: Spring Boot - TEST instance
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    url: "jdbc:h2:mem:test-api;INIT=CREATE SCHEMA IF NOT EXISTS dbo\\;CREATE SCHEMA IF NOT EXISTS definitions;DATABASE_TO_UPPER=false;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=false;MODE=MSSQLServer"
    name:
    password:
    username:
    initialization-mode: never
    hikari:
      schema: dbo
  jpa:
    database: H2
    database-platform: org.hibernate.dialect.H2Dialect
    show-sql: true
    hibernate:
      ddl-auto: create-drop
  test:
    database:
      replace: none

Have you an idea of what is wrong on my code ? The repository is well anotated and written on src/main/java on a sub-package : com.domain.repository

Thanks in advance.

EDIT : The trace of the error :

Solution

  • I found a way to pass tests : no need to create a main function, only a @SpringBootConfiguration annotation on the ProjectCommonsTestApplication is needed.
