How can I test all of the following methods code? I want to play scenarios when all of them are happening to see if my code works for save/restore process of an activity. So what should I do in the Emulator to get all methods tested?

public class Activity extends ApplicationContext {
     protected void onCreate(Bundle savedInstanceState);

     protected void onStart();

     protected void onRestart();

     protected void onResume();

     protected void onPause();

     protected void onStop();

     protected void onDestroy();
 }
