How to Break your App - Workshop - Testbash 2015


Published on

Mobile phones are available since the middle of the 1980s. Since then, the devices changed savagely but the biggest change happened in 2007, when the first iPhone was presented by Apple. Since then, the mobile smartphone market knows only one direction – UP! Since 8 years touch devices are everywhere, from smartphones to tablets.

More than 2 millions apps are available for download in the stores of the biggest vendors and this number is still increasing. There are apps for photos, music, games, office and many more categories just to name some of them.

But what about the quality of those apps? Are those apps reliable, trust worthy, easy to use, well developed and tested? The latest world quality report from Sogeti shows that almost half (45 percent) of mobile apps are not well tested in terms of functionality, performance and security.

This workshop includes insights into the challenging job of mobile testing from native to web apps. Best practices will be provided to become a better mobile tester. Besides that, this workshop will show different test techniques from functional to non functional mobile testing, test automation tools and how to handle the device fragmentation.

The workshop will not include practical mobile test automation. However, the participants will be able to test different mobile apps manually based on the content of the workshop.
