Due to the situation, that we've already had more that 7000 lines of code in this file and it contains different test cases, it is reasonably to divide it into smaller files. This patch includes test cases that are connected with capabilities and getting volumes by active window test cases. Change-Id: If59f29b2fe6ebc526bf2f08a34f45ef5303442ce
