java - org.mockito.exceptions.misusing.InvalidUseOfMatchersException when trying to create custom argument matcher -

i’m using mockito 1.10.18. i’m trying create custom argument matcher method has following signature …

saveresult[] com.sforce.soap.enterprise.enterpriseconnection.update(sobject[] sobjects) throws connectionexception 

i have written following custom argument matcher …

class accountmatcher extends argumentmatcher<sobject[]>  {     private set<string> idlist = new hashset<string>();     accountmatcher(final set<account> mainlist)     {         (final account acct : mainlist)         {             idlist.add(acct.getid());         }   //     }         public boolean matches(object param)      {         final sobject[] compset = ((sobject[]) param);         final set<string> compidlist = new hashset<string>();         (final sobject acct : compset)         {             compidlist.add(acct.getid());         }   //         return util.twosetsmatch(compidlist, idlist);     }   // matches  } 

however, when try , set in junit test …

    final set<account> firstbatch = new hashset<account>();     firstbatch.add(acct);     final sobject[] firstbatchaccts = matchers.argthat(new accountmatcher(firstbatch));     mockito.verify(mockconnection, mockito.times(1)).update(firstbatchaccts); 

i following exception when run …

this because you've extracted firstbatchaccts (the result of matcher call) variable, not method. argthat , other mockito matchers work via side-effects, have called @ right time.

verify checks empty stack of matchers, resets expectations on mock don't interfere verification. matcher calls happen, , call method verified completes process: clears stack, checks method call happened, , switches mock stubbed behavior (if any).

the way have it, argthat gets called, , call verify happens, , verify checks no unused matcher calls have happened. triggers exception.

instead, inline call:

verify(mockconnection).update(argthat(new accountmatcher(firstbatch))); 

...or make method call instead, keeps order right:

public sobject[] arraymatchingaccounts(set<account> accountset) {   return argthat(new accountmatcher(accountset)); }  verify(mockconnection).update(arraymatchingaccounts(firstbatch));
