I use minitest/spec as my testing style, including ending test files with _spec.
It's easy enough setting up Rake to run your specs correctly, just put this in your Rakefile:
# Rakefile require 'rake/testtask' Rake::TestTask.new do |t| t.pattern = "spec/*_spec.rb" end
Set the testing task as the default one for extra key-savingnessness:
# Rakefile task :default => [:test]
