java - Not able to return value when using the following methods Mockito.when(), PowerMockito.when(),Mockito.doReturn() -

following classes

i have interface following method.

the interface follows , has 1 of method

public interface simpledocumentmanager{      public list getuserdocidofrelateddocumentsfortemplate(string doctype, list<string> templatenames,zonecriteria mainzonecriteria,list<zonecriteria> detailzonecriteria);     } 

note : zonecrieria pojo class

i have abstract super class , have init method in it, have sub class extends super class , overrides init method, , in sub class init method call respective service method. code following classes follows.

public abstract class superclass{     public void init( ){      } }  public class subclass extends superclass  {             public void init(){            list<map<string, object>> orderslist =  getsimpledocumentmanager().getuserdocidofrelateddocumentsfortemplate(orderconstants.type_name, arrays.aslist(getoriginaltemplatename()), getcriteriamap(primaryrow), collections.emptylist());      }       } 

in above method zonecriteria have written private method in sub class

private zonecriteria  getcriteriamap(){     logic returns zonecriteria. } 

the above method used 1 of parameter returns zonecriteria when call method present in simpledocumentmanager.

and here test case sub class

@runwith(powermockrunner.class) @preparefortest({servicelocatorbeanfactory.class})  public class testclass {      @before     public void initialize(){         powermockito.mockstatic(servicelocatorbeanfactory.class);         powermockito.mockstatic(businessrulesutil.class);     }       @test     public void testsubclass(){          map<string, object> map = new hashmap<string, object>();         map.put("id, "por0000001");         list<map<string, object>> aslist = arrays.aslist(map);          simpledocumentmanager simpledocumentmanager = mockito.mock(simpledocumentmanager.class);         powermockito.when(servicelocatorbeanfactory.getservice(simpledocumentmanager.class)).thenreturn(simpledocumentmanager);          powermockito.when(simpledocumentmanager.getuserdocidofrelateddocumentsfortemplate(mockito.anystring(),mockito.anylist(),mockito.any(zonecriteria.class),mockito.anylist())).thenreturn(aslist);          mockito.when(simpledocumentmanager.getuserdocidofrelateddocumentsfortemplate(mockito.anystring(),mockito.anylist(),mockito.any(zonecriteria.class),mockito.anylist())).thenreturn(aslist);          mockito.doreturn(aslist).when(simpledocumentmanager).getuserdocidofrelateddocumentsfortemplate(mockito.anystring(),mockito.anylist(),mockito.any(zonecriteria.class),mockito.anylist());           subclass subclass = new subclass();         subclass.init();         subclass = mockito.spy(subclass);         subclass .init();      } 

i have used 3 ways return value when method in simpledocumentmanager called. following 3 ways

1.powermockito.when(simpledocumentmanager.getuserdocidofrelateddocumentsfortemplate(mockito.anystring(),mockito.anylist(),mockito.any(zonecriteria.class),mockito.anylist())).thenreturn(aslist);  2.mockito.when(simpledocumentmanager.getuserdocidofrelateddocumentsfortemplate(mockito.anystring(),mockito.anylist(),mockito.any(zonecriteria.class),mockito.anylist())).thenreturn(aslist);  3.mockito.doreturn(aslist).when(simpledocumentmanager).getuserdocidofrelateddocumentsfortemplate(mockito.anystring(),mockito.anylist(),mockito.any(zonecriteria.class),mockito.anylist()); 

but none of call returns me value. when debug code getsimpledocumentmanager() returns mocked object, method not called.

also have created subclass object in 2 ways. follows

1. directly instantiated subclass in test method follows      subclass subclass = new subclass();     subclass.init();  2.did spy of instantiated subclass      subclass subclass = new subclass();     subclass = mockito.spy(subclass );     subclass .init(); 

when method getsimpledocumentmanager().getuserdocidofrelateddocumentsfortemplate(orderconstants.type_name, arrays.aslist(getoriginaltemplatename()), getcriteriamap(primaryrow), collections.emptylist())

is called want return "list<map<string, object>>" doing

map<string, object> map = new hashmap<string, object>(); map.put("user_doc_id", "por0000001"); list<map<string, object>> aslist = arrays.aslist(map); 

and returning aslist in thenreturn() follows thenreturn(aslist);

while preparing zonecriteria check value , if value not present have userdefined exception thrown.

so when execute test case validation exception instead should return list have prepared.

i have gone through different links in stack overflow , not answer. following links. link1

please help
