Application testing for VDI(Windows XP to Windows 7)


I am migrating users from XP to win7 VDI.
As part of UAT for application testing could anyone advice to what level applications should be tested.If we try to test each and every functionality of an application then UAT is going to last years.
Can anyone guide what guidlines should be followed for testing applications both web apps and fat client apps as part of this desktop virtualization project.Most of the applications are shown as ready for windows 7 in appdna.Still project demands to do an UAT.

How we have approached this in the past, the Design/Implementation Team performs Basic Testing of the Applications.

e.g. if it's Microsoft Office, Create, File and Print New and Old Documents etc

Login/Logout, Concurrent Usage, start at 1 user login logout, and 100 users login/logout etc

Virus Scan all 100 User Desktops etc

Generally Microsoft Applications are well behaved, but sometimes, functions that Advanced Users use, catch us out, as we confess we are not Office Power Users.

We then Engage the Power Users in the Business, and form a User Group to discuss "how they use the applications", and any special applications or databases, that are specific to their business, day to day routines, and Work with them to complete testing.

e.g. Large Excel Spreadsheets with hundreds of Macros, which link to other Spreadsheets etc

So do you advise we do basic testing like loging in and say printing, browse major screens,post few transactions.Some applications generates reports on user test that etc..but no full fledge product testing.

We would recommend you complete basic testing, as much as you can do, as you will not be experts, Users are!

Then engage the users, seek out Power Users in the Business, get their help.

Ask them to complete a weeks business on the new project.

Only users can really test the environment, the more testing you do (users do), the less issues you will experience come, rollout.

and yes testing does take time.
