The best balance between size and readability is probably the
following:

  find_test_dir

Of course, the method "find_test_dir" must be implemented somewhere,
but you won't have to read it very often, and you can just use the six
lines you've written above.

However, I would use the 'pathname' library to clarify some of the
code.
