java - Mock not properly worked -

i want use tdd in current app , try create tests. in case need send message support, , if ok return true. when start tests fail, because actual , expected result not same.

when debug test, see, mockito put mocks need, sender.sendsupportmessage() steel return false. can explain me what's going wrong?

public class supporttests {      @rule     public mockitorule rule = mockitojunit.rule();      @mock     supportcontract.isupportmessagesender sender;     @mock     currentuseroperations currentuseroperations;      private supportmessage stubsupportmessage;     private string message;      @before     public void init(){         message = "message";         stubsupportmessage = new supportmessage(1, message, null);     }      @test     public void testsendmessagetosupportshouldbedone (){         support support = new support(sender, currentuseroperations);           when(currentuseroperations.getcurrentusersystemid())             .thenreturn(long.valueof(1));         when(sender.sendsupportmessage(stubsupportmessage))             .thenreturn(true);          boolean actualresult = support.sendmessagetosupport(message);          assertequals("sending message support failed.", true, actualresult);     }  }   public class support implements supportcontract.isupport {      private supportcontract.isupportmessagesender sender;     private currentuseroperations currentuseroperations;      public support(supportcontract.isupportmessagesender sender, currentuseroperations currentuseroperations) {     this.sender = sender;     this.currentuseroperations = currentuseroperations;     }      @override     public boolean sendmessagetosupport(string message) {         long usersystemid = currentuseroperations.getcurrentusersystemid();          dateformat dateformat = new simpledateformat("dd/mm/yyyy hh:mm:ss");          supportmessage supportmessage = new supportmessage(usersystemid, message,             dateformat.format(calendar.getinstance().gettime()));          return sender.sendsupportmessage(supportmessage);     } } 

ok. found solution.

as see, in testmethod use stubsupportmessage, instantiated in @before init method.

also, in support class see supportmessage supportmessage = new supportmessage(...), , these support messages not same stubsupportmessage != supportmessage.

so, need rid of different objects. problem solved code:

when(sender.sendsupportmessage(any(supportmessage.class))).thenreturn(true); 

where any object of supportmessage class can used.

test class now:

public class supporttests {  @rule public mockitorule rule = mockitojunit.rule();  @mock supportcontract.isupportmessagesender sender; @mock currentuseroperations currentuseroperations;  private string message;  @before public void init(){     message = "message"; }  @test public void testsendmessagetosupportshouldbedone (){     support support = new support(sender, currentuseroperations);      when(currentuseroperations.getcurrentusersystemid()).thenreturn(long.valueof(1));     when(sender.sendsupportmessage(any(supportmessage.class))).thenreturn(true);      boolean actualresult = support.sendmessagetosupport(message);      assertequals("sending message support failed.", true, actualresult); }  }
