Ignore MongoDB socket connection on Spring Test

I am using mongo in my spring project, but I cant connect to mongo server. Anyone knows a way to ignore this bean when executing tests, because sometimes I dont have the mongo server up and I dont want that this build fail.

I really like to know if I can ignore it using SpringRunner.

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { Application.class })
public class ApplicationTests {
    @Test
    public void contextLoads() {
    }
}

Stacktrace:

Caused by: org.springframework.dao.DataAccessResourceFailureException: 
Timed out after 30000 ms 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.MongoSocketException: localhost}, caused by {java.net.UnknownHostException: localhost}}]; nested exception is com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches WritableServerSelector.

PS I stopped the mongodb at localhost intentionally.
