in SDLC , you create your app first ,and write the test cases depending on the module you select ( if it is agile, you get a potion of it and develop that till end or vice versa)
but with TDD , you create the test cases first and write your code accordingly , here its a fact that always frist test case run would fail since the application haven't been built yet.



hope that helps

 hey lakshminarayan ;

1 )

cairngorm is a MVC framework which is a combination of (MVC / singleton / observer)
its a micro architecture which helps to loosely couple our views and data for better controlability.
i think there are so many explanations about it in the web .
which you should search on if you have time ,

simply what i can say is that

you can have your view logic (basic UI ) in the view.
and from that we will dispatch events when we need to invoke back end calls

those events will call up a command class where you dispatch your business logic in the delegate.
so in order to bind the event and the  command together we use a controller .thus when a  event is created it will be binded to a specific command/ commands in the controller.
so automatically command get called when we dispatch and event from the view.
the best part of it is
view doesn't know which command was invoked and or neither the event.
so there can be multiple commands listerning to single event or vice versa depending on the requirment.
you can have composite event which handle multiple events by type.
command class will be implemented on Iresponder Interface , where it will hold the control until the asynchronous function call .
so that on result you can send the data to model () [where we keep data which is our singlton class]

each view will be bind to a specific data variable in model, since when the model is updated ,view will be automatically notified and
updated.

there are lots of other things on it ,feel free ask any if you having trouble in starting up.






2) im not a java guys since i would not be the best person to answer the spring flow. do post me if got a reply as well so that i also can learn from it ;-)

and regarding performance testing/ tuning
if you are using flex/flash builder you can simply use profiler .
check which components has more memory ,what are the loop holes , which methods are slow .....and soo many other things.
profiler is a excellent piece of software when it comes to performance tuning the application .

but if you are open source and unable to use built in flex profiler , what i would suggest is to grab a free web proxy which support amf data (depending on your back end)
and see what methods /and variable size does the harm ....

hope the information make sense.
 let me know if there are any doubts..
