testing process.

[mobi_dev]

Hi,

I would like to know the process of the app testing scenario by the apple guys, for the app to be submitted to the Appstore.

If any one have idea please share..

To be clear I have to following doubts,

i) Do apple use any instruments leaks or such to know whether any memory leaks are in the application.
ii) What HIG(Human Interface Guidelines other than tat are on the document of apple) do they follow to approve the app.
