I have signed up for all the trainings I could find on this topic so I will close this thread and call it another success.
we need more information. are you testing on web apps? did you configure the browsers so that it doesn't auto update along with the other preparation settings? are you using object oriented actions, or unintentionally using coordinate based actions? do you see the object name mapping change alot with frequent "object not found" errors? do the object names frequently end in random or sequential alphanumeric characters? if you do see that the name mapping changes frequently, are you using the self healing mode? which may also change name mapping in an unintended way... need screenshots of your code/keyword tests, name mapping, object under test, etc.
the video you linked is for dynamic name mapping objects. if that's your problem, it could really be as simple as that.
desktop application, one program running the same task over and over.
I have had similar issues. Sometimes test works perfectly, sometimes not .
Biggest issue was poor or missing name mapping. I fixed namemapping and test where much much reliable. Other thing is timing. Some operations take sometimes more time than usually (windows is doing something on background etc). For example in my test I preview report and then try to close that preview. Usually one report takes 2-3 seconds but sometimes it can be 10 secs.
I don't know if that helps, but these are my experiences. My apps are written in Delphi 2007.
