Spring test: ApplicationContext configuration classes (spring data mongodb) - spring

Question

I only want to test mongo related code. This is my test code snippet:
#RunWith(SpringRunner.class)
#ContextConfiguration(classes = {MongoConfig.class})
#SpringBootTest
public class ModelTest {
#Autowired
private MongoTemplate mongoTemplate;
As you can see I'm using #ContextConfiguration in order to only load Mongo related configuration:
#Configuration
public class MongoConfig {
#Bean
public CustomConversions customConversions(){
List<Converter<?, ?>> converters = new ArrayList<Converter<?, ?>>();
converters.add(new ReferenceWriterConverter());
return new MongoCustomConversions(converters);
}
}
As you can see it's only intented to load custom converters are going to be used by mongoTemplate in order to serialize objects to mongodb database.
Also, src/test/resources/application.properties is:
spring.data.mongodb.host: localhost
spring.data.mongodb.port: 27017
The problem is that when I'm trying to run test it's getting me an Unsatisfied dependency expressed through field 'mongoTemplate':
UnsatisfiedDependencyException: Error creating bean with name 'net.gencat.transversal.repositori.digital.mongo.ModelTest': Unsatisfied dependency expressed through field 'mongoTemplate'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.data.mongodb.core.MongoTemplate' available

Any ideas?

Seems issue you are trying to load custom mongo configuration #Bean client here or extend AbstractMongoConfiguration.
change your database name here instead of demo
#Configuration
public class MongoConfig extends AbstractMongoConfiguration {
#Override
protected String getDatabaseName() {
return "demo";
}
#Override
public MongoClient mongoClient() {
return new MongoClient("localhost", 27017);
}
#Bean
public CustomConversions customConversions(){
List<Converter<?, ?>> converters = new ArrayList<Converter<?, ?>>();
converters.add(new ReferenceWriterConverter());
return new MongoCustomConversions(converters);
}
}
