Ken, I usually have a shell buffer nearby and go there to inspect the failed tests when I get no output. The problem is that shell blocks do not capture stderr. John Kitchin wrote a blog post <http://kitchingroup.cheme.cmu.edu/blog/2015/01/04/Redirecting-stderr-in-org-mode-shell-blocks/> about this problem and provided a solution that may work for you, but I have not tried it yet.
