Spring Data MongoDB - indexes & junit tests

[octix]

Hello,

I have a small problem with indexes in my integration tests. Basically I defined a few indexes (1 simple and 1 compound), but it's not being created when I run my integration tests... They are there if I run my web app, but missing when I run integration tests.

Does anyone know if it was designed this way? Basically I'd like to test a unique index constraint that it works, since my app has core and web components.

To have a rough idea, this is what I have:

//AbstractIntegrationTest.groovy
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-core-context.xml")
@ActiveProfiles("test")
abstract class AbstractIntegrationTest {
...
}

//MyServiceTest.groovy
class MyServiceTest extends AbstractIntegrationTest {
    @Autowired
    MyService myService
    
    @Test
	void test_unique_index() {
	 /// some crud
	 myService.save(new Something())
	}
}

//Something.java
@Document
@CompoundIndexes(value = { @CompoundIndex(name = "res_ag_idx", def = "{'resource': 1, 'agent': 1}", unique = true) })
public class Something {
	@Id
	private ObjectId id;

	@DBRef
	private Resource resource;

	@DBRef
	private Agent agent;

	@Indexed
	private int status;
 ...
}

//test-core-context.xml
<beans ...>

	<import resource="classpath:me/demo/my/core/config/core-context.xml" />
	
	<beans profile="test">
		<bean id="settings" class="org.springframework.beans.factory.config.PropertiesFactoryBean" p:location="classpath:test.properties" />
		<mongo:mongo host="${mongo.host.name}" port="${mongo.host.port}" write-concern="SAFE"/>
		<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate" c:mongo-ref="mongo" c:databaseName="${mongo.db.name}" />
	</beans>
	
</beans>

//core-context.xml
<beans ...>
	<context:annotation-config />

	<context:component-scan base-package="me.demo.my">
		<context:exclude-filter type="annotation" expression="org.springframework.context.annotation.Configuration" />
	</context:component-scan>

	<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
	
	<context:property-placeholder properties-ref="settings" />
	
  	<mongo:repositories base-package="me.demo.my.repository" />	

</beans>

Thank you in advance for any input.

Ok, finally I figured it out...

mongoTemplate.dropCollection() in my @Before annotated method will drop collection including all indexes, after which it won't re-initialize indexes... So, instead of dropping collection, I have to delete all data in order to preserve indexes.

Basically

mongoTemplate.remove(new Query(), Domain.class) instead of mongoTemplate.dropCollection(Domain.class)

Thanks.
