How do I import configuration classes in a @DataJpaTest in a SpringBootTest?

Question

I have a SpringBoot Application and I a config package with

@Configuration
@EnableJpaAuditing
public class PersistenceConfig {
}


        

Answer 1

You can try this: annotate PersistenceConfig with @ComponentScan to enable component scanning in Spring.

@Configuration
@EnableJpaAuditing
@ComponentScan(basePackages = "com.yourbasepackage")
public class PersistenceConfig {
}

With no further configuration, @ComponentScan will default to scanning the same package as the PersistenceConfig class.

And add the @Context-Configuration annotation to tell it to load its configuration from the PersistenceConfig.class.

@RunWith( SpringRunner.class )
@DataJpaTest
@ContextConfiguration(classes=PersistenceConfig.class)
public class PersonRepositoryTest {

    // Tests ...
}

Answer 2

A solution is to use @Import to import your configuration to the configuration done by @DataJpaTest. This is my understanding of @Import.

@RunWith(SpringRunner.class)
@DataJpaTest
@Import(AuditConfiguration.class)
public class AuditTest {
}

with AuditConfiguration that enables auditing

@Configuration
@EnableJpaAuditing
public class AuditConfiguration {
}

After @georges van post I have found out that ALL configuration classes get also picked up by just adding one line in the test:

@RunWith( SpringRunner.class )
@DataJpaTest
@ComponentScan(basePackages = "com.basepackage.config")
public class PersonRepositoryTest {

    // Tests ...
}

If someone only wants ONE specific configuration class you can do:

@RunWith( SpringRunner.class )
@DataJpaTest
@ContextConfiguration(classes=MyConfig.class)
public class PersonRepositoryTest {

    // Tests ...
}

Or multiple classes with:

@ContextConfiguration(classes={MyConfig1.class, MyConfig2.class})
