Is there any magazine that specializes in testing of mobile applications ?
None that I know of.
There is a book title that I've added that may be of help. I posted the title to the web testing forum. The book concerned testing web applications.
Hope this helps,
I checked Amazon.com and found a couple of titles on testing web applications that may be beneficial:
1. Testing Applications on the Web: Test Planning for Mobile and Internet-Based Systems, Second Edition by Hung Q. Nguyen, Bob Johnson, Michael Hackett, Hung Q. Nguyen, Robert Johnson, Michael Hackett
Overview: "The goal of this book is to help you effectively plan for and conduct the testing of Web-based applications developed for fixed clients, systems
2. Once It's Down It's Too Late: Web Applications Testing and Monitoring
Overview: Downloadable PDF that is pricey off of Amazon.com
3. The Web Testing Handbook
by Steven Splaine, Stefan P. Jaskiel, Alberto Savoia
Overview: "We're living in the age of convergence, and technology is the catalyst that's bringing us all together..."
None that I have found - (in English or in Hebrew)
