The Extreme Continuous Builder is to allow you to run your project's unit tests while you are working on it. You should receive updates via Growl.
First you will need to have Growl installed... then make sure you have it set to accept network connections. You will also need to install the ruby-growl gem:
gem install ruby-growl
Next add the plugin to your rails project:
./script/plugin install \
http://xconbuild.rubyforge.org/svn/plugin/trunk/extreme_continuous_builder/
Once the plugin is installed, try the following to begin testing:
while sleep 10
do
rake xcb:run XCB_LOGPATH=~/Desktop/xcb_result.txt &> /dev/null;
done &
Enjoy!
