Currently, it is required for the shell's working directory to be in
the repo's test/ directory in order for the tests to run correctly.
This also applies for the static analysis checker.
The reason for this is that paths in the test orchestration code are
defined relative to the test directory. Instead, and since none of
these scripts are modules that will in the forseeable future be
imported into other files, we update all paths to be relative
to the absolute path of the script's file itself.
