I am a last year BSc IT student. From past 6 month I was trying to create a windows desktop application by my own. In fact I am almost done with the 90% of the part, just need to test the software completely but this is exactly the place where I am stuck. I wanted to test this software but unable to do it manually. I know even if I test the software manually I wont be able to target all the aspects of testing. This is the reason why I am here. Can anyone of you let me know the best software testing utility which can help me testing my software? Even if you suggest me with one such tool I would be very much helpful but make sure that the suggested one should be powerful and well rated.
