Hello, zubactik, you wrote: Z> In that case I can wish good luck only. To automate such - the strange desire and, quite probably, ungrateful occupation. Z> we had active when I such automated, but to me carried. In the first I had control buttons, and I pressed on them. The scene changed, I did a screenshot, then screenshots compared. As there was the active development and position of the camera in a scene changed, especially stable it was not for the natural reasons. But somehow worked, and like even benefited. Z> if it is necessary to move, I all the same would go by the way of adding to application - or carrying out of any objects from a scene (that our developers too did, but any more I do not remember than attempt of operation with it ended) that could cling them, or control of a scene through any auxiliary debug interface. Hemorrhoids quite it can appear less. Also it is quite possible test scripts so to avoid necessity to drag something on a scene. Z> anyway successes! You need to check up a little , most likely. To it be ready. Well and mentioned Sikuli just like specialized earlier on cliques by comparing of pictures. Z> but, I will repeat, at first it is necessary to think as not to do such tests. Though for 4 years something could exchange and already with determination of objects on a scene masters to work learned. There will be a desire - . Month through 3 I can revive old customs and try to be engaged. Many thanks for so torn answer. I agree - automatic testing of a 3D-scene directly - almost as "a way of the kamikaze". For what to "be hooked" at AutoCAD'a is - all commands can be entered through command line. But tests only through command line would be defective. Therefore I check additional possibilities.
