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
