i trying unit test presenter , view in android app following code :

@runwith(mockitojunitrunner.class) public class moviedetailspresenterunittest {      @mock     networkapi mnetworkapi;      @mock     networkservice mnetworkservice;      @mock     moviedetailscontract.view mview;      @mock     moviedetailsactivity mmoviedetailsactivity;      private moviedetailspresenter mmoviedetailspresenter;       @before     public void setup() throws exception {         this.mmoviedetailspresenter = new moviedetailspresenter(mnetworkservice, mmoviedetailsactivity);     }      @rule     public final rxschedulersoverriderule moverrideschedulersrule = new rxschedulersoverriderule();       @test     public void testmoviedetailsemptyresponse() throws exception {         moviedetails moviedetails = new moviedetails();         when(mnetworkapi.getmoviedetails("abcd")).thenreturn(observable.<moviedetails>just(moviedetails));         mmoviedetailspresenter.loadmoviedetails("abcd");         verify(mmoviedetailsactivity).onsupportnavigateup();     }      @after     public void teardown() throws exception {         rxandroidplugins.getinstance().reset();     } }

but error :

your mocks mnetworkapi , mview never injected anywhere , hence stubbing 

when(mnetworkapi.getmoviedetails("abcd")).thenreturn(observable.<moviedetails>just(moviedetails));

will never happen. since can't see source code moviedetailspresenter guessing lack of stubbing leads logic of onsupportnavigateup() method never being called. need make sure mocks included in mmoviedetailspresenter marking @injectmocks.

@injectmocks private moviedetailspresenter mmoviedetailspresenter;

although can't 100% sure until see code more of classes.
