Bradley Wright 12 December 2009 Great article Ross; very useful and hopefully inspires testing in a whole new generation of front end coders. However, I note that sleuth.js isn’t linked to anywhere—any chance you could put it on GitHub or somewhere similar for download? Might be helpful to those who want to get started on testing their own sites. PS: Drew, are you sure this comment system takes valid Textile? I can’t generate code blocks (see sleuth.js above).
