How did you go about testing your program? what were the results of that testing?

Today i was working in Fireworks, trying to create my animation. to test it, i had to press the "play" button and when i did; it turned out to have quite a few glitches in it and it wasn't as smooth as i wouldve liked. turns out there were a few screens in which i had unintensionally moved link and the spaces between movements were to far apart. i needed to reedit the pictures for every screen in order to clear up the glitches.
