Test tries to connect localhost instead of using embedded mongodb by @DataMongoTest

I have spring app which uses mongoRepository. I want to have an integration to test my repository by using @DataMongoTest. For some reason my test tries to connect localhost for mongo and gets timeout. I am using this as a dependency:

<dependency>
  <groupId>de.flapdoodle.embed</groupId>
  <artifactId>de.flapdoodle.embed.mongo</artifactId>
  <scope>test</scope>
</dependency>

org.springframework.dao.DataAccessResourceFailureException: Timed out while waiting for a server that matches WritableServerSelector. Client view of cluster state is {type=UNKNOWN, servers=[{address=localhost:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.ConnectException: Connection refused}}]

My test is as below:

@DataMongoTest
class MarketRepositorySpecIT extends Specification {

    @Autowired
    EmployeeRepository myRepository

    def "findByIdWillReturnData"() {
        given:
        def data = testData()
        myRepository.save(data)

        when:
        def result = myRepository.findById("id", EmployeeDocument.class)

        then:
        result.isPresent()
    }

and the repository is :

@Repository
public interface EmployeeRepository extends MongoRepository<EmployeeDocument, String> {}

Why it tries to connect mongoDb in localhost instead of using embedded mongo db ?
