Spring boot and mongo db gitlab CI/CD - mongodb

Question

I have set up a spring boot API that does CRUD operations with MongoDB running.
I need to run the commands on CI with hosted MongoDB automatically using GitLab
mvn clean install -B
and
mvn clean test
from .gitlab-ci.yml.
com.mongodb.MongoSocketOpenException: Exception opening socket

Thanks for the prominent answers/ comments
I was able to solve the problem using embed.mongo in such a way that while the normal API run's it uses actual Mongo store hosted. The tests will be run on embed.mongo
Dependency added :
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<version>1.48.0</version>
<scope>test</scope>
</dependency>
Common Mongo config
#Configuration
#EnableAutoConfiguration(exclude = { EmbeddedMongoAutoConfiguration.class })
public class MongoConfig {
}
Annotations used for the test class
#ContextConfiguration(classes = {MongoConfig.class})
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
#AutoConfigureDataMongo
