Their is nothing like Testing of QVF or QVW file..
When you finish the development, following point need to be cover before publishing it:
1) Performance Optimization(Script/UI Level)
2) Data Modeling
3) Data Validation
4) Completing Dashboard as per required By Customers
5) Customer Acceptance for Publishing
After all these you can live your app.
The rule(not for everyone) is to develop your model in QV then move to QS.
QV has a range of testing tools.
If your are able to copy/paste your script to QV - do it,test it.
I totally agree with Robert, testing your Data Model in QlikView will be really help full.
And on if you need your testing team or the stake holders to have a look at it before publishing the app to the live stream, i would suggest you to create a testing stream and grand access to the ones who have to ratify your developments. This would help you manage your developments as well.
