unit testing - How to inject mock in parent class with Mockito? -

i'm using mockito mock services..

how can inject mocks in parent class?

sample:

public abstract class parent(){      @mock     message message;  }  public class mytest() extends parent{      @injectmocks     myservice myservice //myservice has instance of message      //when put @mock message here works } 

when run tests message in parent stay null

two ways solve this:

1) need use mockitoannotations.initmocks(this) in @before method in parent class.

the following works me:

public abstract class parent {     @mock     message message;      @before     public void initmocks() {         mockitoannotations.initmocks(this);     } }  public class mytest extends parent {     @injectmocks     myservice myservice = new myservice(); //myservice has instance of message     ... } 

2) if want use @runwith(mockitojunitrunner.class) above class definition, must done in parent class:

@runwith(mockitojunitrunner.class) public class parent { ... 

note declaring @mock in both parent , mytest class cause injected object null. have pick want declare this.
