[GSOC][RFC PATCH 0/1] microproject: use test_path_is_* functions in test scripts

This patch is submitted as a microproject for the application to the GSOC. Upon previous dicussion[1], this patch replace the test shell commands with the helper functions as follows:

- 'test -f'   --> 'test_path_is_file'
- 'test ! -f' --> 'test_path_is_missing'

In the context of this file, 'test ! -f' is meant to check if the file has been correctly cleaned, thus its usage has been replaced with 'test_path_is_missing' instead of '! test_path_is_file'.

Submitting as RFC to ask whether there is room for further improvements:

Would you like to see something like 

''' test_path_is_missing file1 && test_path_is_file file2 && test_path_is_missing file3 && test_path_is_file file5 '''

changed into 

''' test_path_is_file file2 && test_path_is_file file5 && test_path_is_missing file3 && test_path_is_missing file1 '''

where all the test_path_is_file are grouped before and followed by all the test_path_is_missing (or the other way around) to enhance readability of the code?

Thanks, Vincenzo
