<p>I'm having a test hang in our rails app can't figure out which one (since it hangs and doesn't get to the failure report).  I found this blog post <a href="http://bmorearty.wordpress.com/2008/06/18/find-tests-more-easily-in-your-testlog/" rel="noreferrer">http://bmorearty.wordpress.com/2008/06/18/find-tests-more-easily-in-your-testlog/</a> which adds a setup hook to print the test name but when I try to do the same thing it gives me an error saying wrong number of arguments for setup (1 for 0).  Any help at all would be appreciated.</p>

What test framework are you using?  Test/Unit?
I would take a look at RSpec which would provide a little more context for your tests.  You can also get a nice HTML report that looks like this:
RSpec Result http://myskitch.com/robbyrussell/rspec_results-20070801-233809.jpg
Had you had any failing tests, the specific test would be red and it would expand to the specific lines where the test failed to provide you more visibility on why the test failed and where you should look to address the issue.
