rcov rake task for rails project

akbloom (Andrew Bloom) — Tue, 11 Sep 2007 16:13:45 GMT

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

Rename keys and return a duplicate hash, or perform the method and modify the current hash.
Check each value in the hash and return true if they are all empty, otherwise return false.



class Hash

  def rename_key(old_key, new_key)

    return Hash.rename_key(self.dup, old_key, new_key)

  end

  

  def rename_key!(old_key, new_key)

    return Hash.rename_key(self, old_key, new_key)

  end

  

  def all_values_empty?

    self.each_value do |v|

      return false if v and v != ""

    end

    

    return true

  end

  

  private

    def self.rename_key(hsh, old_key, new_key)

      hsh[new_key.to_s] = hsh.delete(old_key.to_s)

      return hsh

    end

end
