Spring boot + TestNg using EmbeddedMongoAutoConfiguration

Question

I'm trying to create UnitTests for mongodb operations and came across EmbeddedMongoAutoConfiguration which is provided by spring boot. I'm using morphia to interact with mongodb. I tried going through the post @ How do you configure Embedded MongDB for integration testing in a Spring Boot application?, but didnt help. However i'm not able to get the unit tests to work with EmbeddedMongoAutoConfiguration.

I get the following error while running the test:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.boot.autoconfigure.mongo.MongoProperties org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration.properties; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.data.mongodb.CONFIGURATION_PROPERTIES': Initialization of bean failed; nested exception is javax.validation.ValidationException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

Below are my code snippets:

Mongo Configuration

@Configuration
@EnableAutoConfiguration(exclude = { EmbeddedMongoAutoConfiguration.class })
public class MongoTestConfig {

    @Bean
    public MongoClient mongoClient() {

        return new MongoClient("localhost",37017);
    }

    @Bean
    public Morphia morphia() {      
        return new Morphia();
    }

    @Bean
    public Datastore dataStore() {

        return morphia().createDatastore(mongoClient(), "mydb");
    }
}

Unit test:

@SpringApplicationConfiguration(classes = {MongoTestConfig.class})
public class ResourceImplTest extends AbstractTestNGSpringContextTests{

    @Inject
    MongodExecutable embeddedMongoServer;

    @Inject
    MongoClient mongoClient;

    @Inject
    Morphia morphia;

    @Inject
    Datastore datStore;


  @Test
  public void test() {


  }

}

pom.xml has the required dependency of:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
    <version>1.3.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>de.flapdoodle.embed</groupId>
    <artifactId>de.flapdoodle.embed.mongo</artifactId>
    <version>1.50.5</version>
</dependency>

The stack trace tells you very clearly that you need hibernate-validator in your class path. Did you verify it is present? — guido

Add this dependency:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
</dependency>

Also remove version from MongoDB starter:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

Spring Boot takes case of your versions for these dependencies
