Autotest error

Hello,

I can’t make autotest running on Ubuntu, please help.

Error message:
/.rvm/gems/ruby-1.9.2-p180/gems/test-unit-2.3.0/lib/test/unit/ui/
console/testrunner.rb:336:in `module:Console’: uninitialized
constant Test::Unit::UI::Console::Diff (NameError)

Copied .autotest file from here:
http://automate-everything.com/lang/en/2009/08/gnome-and-autospec-notifications/

What does it mean? Many thanks for your help!

Hi,
can’t solve this problem, please help.

$ autotest
loading autotest/rails-rspec2

output:
`module:Console’: uninitialized constant
Test::Unit::UI::Console::Diff (NameError)

I use Ubuntu10, gems used: autotest, Rspec, ZenTest, redgreen and
spork.

I keep trying, reading different solutions, none helped. Any idea
would be highly appriciated. Many thanks,
Zoli
