QUnut + JSDeferred

• Why it works?
• Need to obtain Deferred instance for testing part from the target.

test('bad use (1) of jsdeferred with qunit.', function(){
  var x = 0;
  Deferred.define();
  next(function(){
    next(function(){ x = 1;
    });
  })
  .next(function(){
    equals(x, 0);
    start();
  });
  stop(100);
});

test('bad use (2) of jsdeferred with qunit.', function(){
  var x = 0;
  Deferred.define();
  next(function(){
    return next(function(){
      x = 1;
    });
  });
  next(function(){
    equals(x, 0);
    start();
  });
  stop(100);
});

test('right way: some thing bit complex using jsdeferred with qunit.', function(){
  var x = 0;
  var d = Deferred.define();

  d.next(function(){
    debug('first next ');
    return next(function(){
      debug('nested next');
      x = 1;
    });
  })
  .next(function(){
    debug('equals next ');
    equals(x, 1);
    start();
  });
  stop(100);
});
