Dan McNeil, over on the Forum:
The test criteria have been reviewed many times before, and tests have been added, changed and removed. But this time, we've taken a more fundamental approach. We have looked at what we believe Symbian Signed should be testing and derived test cases from there. We believe that the two key aims of Symbian Signed are to guarantee the origin of the application and to ensure that the application is "well-behaved" when installed onto the device.
The draft of the test criteria attached which I've posted up for review today is early in the process. We believe that it's important to get as many eyes on this as possible as soon as we can. Developers, OEMs, Operators, Symbian Employees and interested observers of the process all have very valuable opinions on Symbian Signed, and we want to hear from all of you.
