android - JSONObject Unit Testing Always Null -

i have been looking @ hour , can't seem see what's wrong.

jsonobject jsonresponse = new jsonobject(); jsonresponse.put("json", "hi"); string mystring = jsonresponse.getstring("json"); assertequals("hi", mystring);  

result... (the entire method throws throwable). tried try/catch well. same result....

java.lang.assertionerror:  expected :hi actual   :null 

this class using

public class ecusertests(){      @org.junit.test     public void testuserexists(){          try{             jsonobject jsonresponse = new jsonobject();             jsonresponse.put("json", "hello, world!");             string mystring = jsonresponse.getstring("json");             assertequals("hi", mystring);         }catch(jsonexception e){             e.printstacktrace();         } 

i suppose you're running unit test outside of android , compiling against android.jar. lib contains class , interface signatures without implementation.

solution:

either execute unit test in android context (not on pc) or when running on pc, have load "real" json library test.
