Micronaut #Replaces with declarative Client - spock

Question

I am going to use the code from Micronaut Documentation (Declarative Http Client)- And I'm using Spock
PetOperations.java
#Validated
public interface PetOperations {
#Post
Single<Pet> save(#NotBlank String name, #Min(1L) int age);
}
I have a declarative client:
#Client("/pets")
public interface PetClient extends PetOperations {
#Override
Single<Pet> save(String name, int age);
}
My goal is when I run a test class, I want to call (#Replaces) another class (PetDummy) instead of the PetClient, PetDummy class is located in my test folder
#Primary
#Replaces(PetClient.class)
#Singleton
public class PetDummy implements PetOperations {
#Override
public Single<Pet> save(String name, int age) {
Pet pet = new Pet();
pet.setName(name);
pet.setAge(age);
// save to database or something
return Single.just(pet);
}
}
test class:
class PetTest extends Specification {
#Shared
#AutoCleanup
ApplicationContext applicationContext = ApplicationContext.run();
//EmbeddedServer server = applicationContext.getBean(EmbeddedServer.class).start();
PetClient client = applicationContext.getBean(PetOperations.class);
def 'test' (){
given: 'name and age'
when:
client.save("Hoppie", 1);
then:
noExceptionThrown()
}
}
However, at the end PetClient is called, I have as well tried with the #Factory annotation, but no success
PetClient extends PetOperations and PetDummy implements PetOperations, if they both implement then it will make sense to use #Replaces ...
Is there something else I can try out?
Thank you!
Another Issue:
Now that it works, the PetClient is a dependency in my PetService. When I test my PetService, it still calls the PetClient instead of the PetDummy.
I assume it has to do with the applicationContext, you will see
PetService:
PetService {
#Inject
PetClient client;
buyFood(){
//...
Single<Pet> pet = client.save("Hoppie", 1));
}
}
PerService Test:
class PetServiceTest extends ApplicationContextSpecification {
#Subject
#Shared
PetService petService = applicationContext.getBean(PetService)
PetOperations client = applicationContext.getBean(PetOperations.class) //client is not used here
def 'test' (){
given:
when:
petService.buyFood()
then:
noExceptionThrown()
}
}
I think that I need to "get into" the applicationContext from the PetService, to tell "use the PetDummy" implementation (Inside the test class, because the ApplicationContextSpecification belong to another module
The ApplicationContextSpecification is:
abstract class ApplicationContextSpecification extends Specification implements ConfigurationFixture {
#AutoCleanup
#Shared
ApplicationContext applicationContext = ApplicationContext.run(configuration)
/* def cleanup() {
assert !hasLeakage()
}*/
}
The ConfigurationFixture contains the properties for the database(hibernate)

You are already retrieving the PetClient bean implementation:
PetClient client = applicationContext.getBean(PetOperations.class);
Which should provide the replacing dummy bean implementation if called with the appropriate type:
PetOperations client = applicationContext.getBean(PetOperations.class);
