I have a situation here.


We know that whenever MockControls are used, parameters used in the original call either comes from methods' parameter undisturbed or will be a new instantiation.


What if the parameters are disturbed and the method call is made?.. can we mock this method?. I have attached a snipnet of code for better understanding.



Main class method



public void mainMethod(String str,int i)

{

..

str = str.subIndex(2,5);

List work = service1.update(str);

..

}





JUnit Class



MockControl control = createControl(Service1.class);

mockObject = (Service1) control.getMock();




mockObject.update("sampleString");

control.setReturnValue(loadListObjects(),MockControl.ONE_OR_MORE);








I m not able to get the o/p. It says,

assertionFailureError.
Unexpected method call update([])
expected: 0,actual: 1
