Offline websites are not just needed where internet connectivity is not consistent. These lightweight client side storage websites are also useful in SmartPhone world, people can cache the data & work offline & sync the data with servers whenever they want. This talk will help to understand the need, latest technologies available & different challenges faced while testing such websites. Apart from technologies like localstorage, appcache, indexedDB etc we will also talk about how to plan your automation & manual testing.

26. Challenges • How to automate indexedDB?" • How to switch off network in between running automation script?" • Inform exact point of failure" • CI integration" • Which browser to choose for automation testing?
