[PATCH 1/3] test functions: Add new function `test_file_not_empty`

[Rohit Ashiwal <rohit.ashiwal265@gmail.com>]

test-lib-functions: add a helper function that checks for a file and that
the file is not empty. The helper function will provide better error message
in case of failure and improve readability
