and this is a child or subproject pom.xml :

</project>
The child project is in the parent folder and also used tag from parant project.
I made a test class in child project inside eclipse and if i run Junit it gives me this
error :
java.lang.NoClassDefFoundError: org/springframework/data/jdbc/repository/config/AbstractJdbcConfiguration .....

Answer 1

Okey kinda confusing error log but after i change my test class from this
#DataJdbcTest
#AutoConfigureTestDatabase(replace = Replace.NONE)
public class RoleRepositoryTests {
#Autowired
private RoleRepository repo;
#Test
public void testCreateFirstRole() {
Role roleAdmin = new Role("Admin","For Test");
Role savedRole = repo.save(roleAdmin);
assertThat(savedRole.getId()).isGreaterThan(0);
}
}
to
#SpringBootTest
#AutoConfigureTestDatabase(replace = Replace.NONE)
public class RoleRepositoryTests {
#Autowired
private RoleRepository repo;
#Test
public void testCreateFirstRole() {
Role roleAdmin = new Role("Admin","For Test");
Role savedRole = repo.save(roleAdmin);
assertThat(savedRole.getId()).isGreaterThan(0);
}
}
And my application.properties from this :
spring.jpa.properties.hibernate.dialect = com.mysql.cj.jdbc.Driver
to this :
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL8Dialect
Junit Test Runs Successfully.
