How to retrain a Web tester into an IOs tester?

Question

Software testing

There is one manual tester of Web sites and services, a good Middle level. The task is to retrain him into a manual IOs tester as soon as possible.
Tell me what literature to read, where to study, you can take online courses.

Answer 1

Depends on what he "sags" when switching to another platform.
The principles of testing are identical, the process - in general, too.
Problems can arise with understanding:
a) tools (debugging, defect localization, build-run, autotest frameworks)
b) the environment itself (platform features and related tests)
The first is mastered in a week by watching a basic development course on some course.
The second - is mastered mainly due to experience. Basic stuff is easy to google, like:

www.softwaretestinghelp.com/beginners-guide-to-mob...
www.mobileqazone.com/video/video
In general, let a friend read the literature on platform architecture (at a basic level, so that he understands how it works).
Further on the "basics" of testing (to highlight new types of events and tests that need to be taken into account).
And then into battle.
