Do not want to load application.yml when testing with Spring Boot - spring-boot

Question

How can I tell Spring to load only application-test.yml and not application.yml file ?
I have a config class:
#ActiveProfiles("test")
#SpringBootConfiguration
public class MongoTestConfig {
#Autowired
MongoOperations operations;
...
}
And a test class:
#RunWith(SpringRunner.class)
#DataMongoTest
#SpringBootTest(classes = MongoTestConfig.class)
public class TagDefinitionRepositoryTest {
...
#Test
....
}
I've tried to add :
#TestPropertySource(locations = {"classpath:application-test.yml"})
#ContextConfiguration(initializers = ConfigFileApplicationContextInitializer.class)
To my config class but it doesn't work: Spring still load application.yml

Answer 1

I don't think you can tell Spring Boot to ignore application.yml completely. What you can do though is to override all the non desired properties using test specific property files.
Based on the code snippet you posted, any property in application-test.yml will override the equivalent property in application.yml.
Spring Boot considers application-test.yml specific to the profile "test" (which has a higher priority over the default application.yml). No annotation #TestPropertySource is needed.
But if you want to choose another name for your properties file, then you can use #TestProertySource, since files indicated in #TestProperySource parameters have higher priority over the others.
You might want to have a look at Spring Boot external configuration rules for resolving properties

I've end up using #SpringBootTest instead of #DataMongoTest
#SpringBootConfiguration
#ComponentScan(basePackages = {"com.package.services"})
#EnableMongoRepositories(basePackages = {"com.package.repositories"})
public class MongoTestConfig {
private static final MongodStarter starter = MongodStarter.getDefaultInstance();
#Bean
public MongoClient mongoClient() throws IOException {
MongodExecutable _mongodExe;
MongodProcess _mongod;
_mongodExe = starter.prepare(new MongodConfigBuilder()
.version(Version.Main.V3_2)
.net(new Net("localhost", 12345, Network.localhostIsIPv6()))
.build());
_mongod = _mongodExe.start();
MongoClient _mongo = new MongoClient("localhost", 12345);
return _mongo;
}
#Bean
public MongoDbFactory mongoDbFactory() throws IOException{
return new SimpleMongoDbFactory(mongoClient() , "test");
}
#Bean
public MongoTemplate mongoTemplate() throws IOException {
return new MongoTemplate(mongoDbFactory());
}
And my test class is:
#RunWith(SpringRunner.class)
#SpringBootTest
public class MyRepositoryTest {
...
