Used in Merb.root/dependencies.yml Tells merb which testing framework to use. Currently merb supports rspec and test_unit for testing

Example

$ sudo gem install rspec
use_test :rspec # this line goes in dependencies.yml (or use_test :test_unit)
$ ruby script/generate controller MyController # will use the appropriate generator for tests
