I\'ve had problems with autotest before which I resolved by downgrading from ZenTest 4.1.4 to 4.1.3.
$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [univers
I had a similar problem which I resolved by downgrading to 4.0.0. Unfortunately I didn't have time to investigate why this happened in the first place, but I would be interested to know.
I had the same problem with Shoulda tests, downgrade to 4.0.0 solved it.
sudo gem uninstall ZenTest
answer yes to the remove binaries question
sudo gem install ZenTest --version '4.0.0'
I can also confirm that simply installing 'autotest-rails' solved the problem for me without having to downgrade ZenTest to 4.0.0
I experienced the same problem. Installing the autotest-rails gem solved it for me. I didn't find it necessary to downgrade ZenTest to 4.0.0 (running 4.1.4).
I struggled with this too. It looks like Rails support was removed from the core autotest library and moved into it's own gem. gem install autotest-rails
seems to get everything working for me.
