On my team, we have FitNesse tests surrounding our system.  We’ve integrated them into our cruise build as well.  We developed custom Xsl sheets so that the cruise build report includes fitnesse information.  We even have our regression FitNesse suite fail the build if any FIT tests fail.  When this happens, the cruise build report shows us the actual FitNesse test that failed with the actual fixture tables.  It’s a great way to report this status.  If you are interested in this technique, my colleague, Steve Donie has posted the Xsl stylesheet on his blog.
