Initializing Mongo DB for Spring Boot Test

Question

I'm building a Spring Boot application that uses Spring Data Repositories with MongoDB. I'm attempting to create a Spock functional Spec to test my repository but I can't figure out the appropriate way to initialize the Mongo DB in preparation for testing. So far I have tried the following:

Do Nothing - This resulted in the same database being used from test to test with my tests failing after.
Drop the database before testing - This resulted in the indexes being lost and me being unable to test my unique indexes.

Here's what I was doing with dropping the database:

@ContextConfiguration(classes = MyApp, loader = SpringApplicationContextLoader)
@ActiveProfiles('test')
class UserRepositoryTest extends Specification {

    @Shared
    boolean mongoReset = false

    @Autowired
    MongoTemplate mongoTemplate

    @Autowired
    UserRepository userRepository

    void setup() {
        if (!mongoReset) {
            mongoTemplate.getDb().dropDatabase()
            mongoReset = true
        }
    }

}

Ideally I'd like to be able to use something similar to the data.sql method provided with JPA repositories.

We usually recommend to rather use the repository to wipe the database (i.e. calling userRepository.deleteAll()). Dropping the database has the downside of wiping all the indexes that might have been created during context bootstrap time.
