Adding a directory to $LOAD_PATH (Ruby)

Question

I have seen two commonly used techniques for adding the directory of the file currently being executed to the $LOAD_PATH (or $:). I see the advantages of doing this in case

Answer 1

Best I have come across for adding a dir via relative path when using Rspec. I find it verbose enough but also still a nice one liner.

$LOAD_PATH.unshift(File.join(File.dirname(__FILE__), '..', 'lib'))
