* Update docs/submodules/sfc from branch 'master'
  - Merge "Clean up Test Case code"
  - Clean up Test Case code
    
    Too much of duplicated code has been obeserved in
    test cases. With this patch a small refactoring is necessery
    to our test cases code. So they can be more generic and
    more flexible.
    
    To achieve that the addition of new parent class is essential, hence
    all the rest test case classes will inherit from the aforementioned
    parent class.
