Cannot create MockBean of interface with generics #5421

Open jjchiw opened 3 years ago

jjchiw commented 3 years ago

I'm not really sure if the title it's correct :/ since I don't really know why the bean cannot be created.....

Task List

Steps to Reproduce

  1. Create two interfaces like this 
    
package ka;

public interface Command { public R execute(); }

package ka;

public interface BarService { public <R, C extends Command> R send(C command); }


3. Create a class where the `BarService` is injected

package ka;

import javax.inject.Inject; import javax.inject.Singleton;

@Singleton public class FooService { @Inject BarService barService;

public boolean alwaysTrue(){
    barService.send(null);
    return true;
}

}

4. Create a Spec using Spock

package ka

import io.micronaut.test.annotation.MockBean import io.micronaut.test.extensions.spock.annotation.MicronautTest import spock.lang.Specification import javax.inject.Inject

@MicronautTest class FooServiceSpec extends Specification {

@Inject
FooService fooService

BarService barService

void 'test it works'() {
    given:
    1 * barService.send(_)

    when:
    def r = fooService.alwaysTrue()

    then:
    r == true
}

@MockBean(BarService)
BarService barService() {
    return Mock(BarService)
}

}


### Expected Behaviour

Pass Test

### Actual Behaviour

Exception cannot load bean

Can you please verify this issue persists with Micronaut 2.5.3?

Hi!

I've the same exception.

I updated Micronaut with sdkman, updated gradle.properties, verified the version in terminal, restart IntelliJ, clean, build and It failed with tests
