I'm trying out on automation testing and was recommended TestComplete, can someone out there pls advise if this is a suitable tools for application such as Windows Media Player or some proprietary Multimedia Player??
Could you please clarify what kind of testing you mean? In any case, I recommend that you download the free 30-day demo version of TestComplete and try it with your application by yourself. Please download it from here: http://www.automatedqa.com/downloads/tc.asp
