Unable to create mock for Authenticator in Junit

[sravs]

My service class has a reference object of org.apache.sling.api.auth.Authenticator;

While I'm trying to implement a test class I'm getting the below error message for Authenticator.

org.apache.sling.testing.mock.osgi.ReferenceViolationException: Unable to inject mandatory reference 'authenticator' for class MyService

I have tried to create a mock object of Authenticator and registering it but the issue is still there. Can you please help me with this.

@Mock
Authenticator authenticator;

@BeforeEach
void setup(){
    context.registerService(Authenticator.class, authenticator);
    context.registerInjectActivateService(new MyServiceImpl(), "title", "My Service");
}

Hi @sravs , Can you try making the authenticator reference optional in your Service class.

@Reference(policy = ReferencePolicy.DYNAMIC, cardinality = ReferenceCardinality.OPTIONAL)
    private volatile Authenticator authenticator;

Thanks,
