http://davidnewton.ca/demos/hyphenation/test.html
There are three tests:
1. csshyphens - tests hyphens:auto actually adds hyphens to text
2. softhyphens - tests that &shy; does its job
3. softhyphensfind - tests that in-browser Find functionality still works correctly with &shy;
These tests currently require document.body to be present
Hyphenation is language specific, sometimes.
See for more details: http://code.google.com/p/hyphenator/source/diff?spec=svn975&r=975&format=side&path=/trunk/Hyphenator.js#sc_svn975_313
If loading Hyphenator.js via Modernizr.load, be cautious of issue 158: http://code.google.com/p/hyphenator/issues/detail?id=158
