I found a really nice eBook from uTest with the topic “The Essential Guide to Mobile App Testing”. The eBook provides a really good overview of the current challenges of mobile app testing and its future. Everyone who is in the mobile app testing area should read it to get an overview and maybe find some points he or she can improve in the daily mobile testing life!
The eBook can be downloaded from
