java - How to write a junit testcase for a void method that creates a new object -

public class supportcontroller{      public void disableuseraccount(string username) throws exception {         useraccount useraccount =                  new useraccount(constants.system, constants.container, username);         useraccount.disableaccount();     } } 

how test useraccount created disabled?

i suggest using mock objects.

besides that, can check junit faq, can find section testing methods return void.

often if method doesn't return value, have side effect. actually, if doesn't return value , doesn't have side effect, isn't doing anything.

there may way verify side effect occurred expected
