I installed the zentest gem, and I cant get autotest to actually run or recognize any tests, it does however recognize when a test file has been modified. here's a snippet:

# Testing updated files
+ /usr/bin/ruby -Ilib:test -e '["test/functional/articles_controller_test.rb", "test/functional/authors_controller_test.rb", "test/functional/collections_controller_test.rb"].each { |f| load f }' | unit_diff -u
Loaded suite .

Finished in 0.000792 seconds.
