Hi, in my company we are currently planing the kick-off event of a new handheld device (some mechanical buttons, some sensors and a ~256x128 pixel LCD color display) and I am in charge to evaluate existing best practices to perform system and validation (CRS) tests beyond what we currently do. I mean, for unit testing this seems trivial, because the the test cases are written by the developers alone and we simply check code coverage. For the system tests and especially for validation tests, the problem seems to be more complex. We have a dedicated team of two testers which are responsible to develop and document all the test cases in DOORS. Both are expert Python programmers. But in previous projects both had problems to really "see" what is displayed on the LCD. Silly or not, sometimes it would have seen reasonable to use a camera to capture the LCD content and to do text recognition and content analysis on the captured frames. On the other hand, is somebody really using cameras for this? Does anybody of you has ever seen such a system? From searching around I have seen some solutions for the automotive sector, but I do suspect that they are much too special. I would really appreciate any comments on that. Maybe I'm thinking much too complicated and I miss a much cheaper solution. Thanks in advance, Bennie
