I'm running into the exact same problem as was posted at: http://stackoverflow.com/questions/1574896/zentest-autotest-not-running-tests. However, nothing on that article is helping me to solve the problem. I have ZenTest and autotest-rails both installed, and yet when I run autotest from the command prompt, I see "loading autotest/rails" and then nothing else happens. No tests are run or anything. I have tried downgrading my ZenTest gem version to no avail. This is very frustrating. I had been trying to follow along with PeepCode's screencast on rspec, but have yet to get autotest to do a single thing. Any suggestions?
