Spring boot + TestNg using EmbeddedMongoAutoConfiguration - mongodb

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>

Answer 1

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
