This task will create a folder (doc/coverage) then run all of your tests and produce HTML with code coverage information in that folder. If you are on a mac it will even open the index.html file up for you automatically
# this requires the RCOV gem to be installed on your system namespace :test do desc "Generate code coverage with rcov" task :coverage do rm_f "doc/coverage/coverage.data" rm_f "doc/coverage" mkdir "doc/coverage" rcov = %(rcov --rails --aggregate doc/coverage/coverage.data --text-summary -Ilib --html -o doc/coverage test/**/*_test.rb) system rcov system "open doc/coverage/index.html" if PLATFORM['darwin'] end end
