You know it’s important to test your app before you publish it, but if you’re testing only your code, you’re testing only part of your app. It’s important to find bugs in your design as well. Otherwise, the app may behave exactly the way your code intends, but users may still find it frustrating and give it low ratings in Nokia Store. In this webinar, Jan Krebber of Digia presents simple methods to find UX bugs and explains how to correct them. These techniques can help you increase your app quality whether you work with a large organisation or completely on your own. The presentation also features exercises, for which you can find sample solutions in Series 40 UI design usability testing webinar — companion article, published in the Nokia Developer Wiki.
