rcov for cucumber and shoulda

There seems to be a lot of bad info out there about this. It’s really quite simple, you just have to make use of the built in tasks provided by cucumber and rcov. The following task definitions will generate coverage reports for cucumber features and rails tests in coverage.features and converage.tests respectively. You’ll also get the overviews for the same reports at the command line when you run the tasks.

require 'cucumber/rake/task'
require 'rcov/rcovtask'

namespace :rcov do

  rcov_opts = ['-T','--exclude /Library/Ruby/Site/*,.rip/*,gems/*,rcov*,features/step_definitions/webrat_steps.rb']

  desc 'Measures cucumber coverage'
  Cucumber::Rake::Task.new(:features) do |t|
    t.rcov = true
    t.rcov_opts = rcov_opts
    t.rcov_opts << '-o coverage.features'
  end

  desc 'Measures shoulda coverage'
  Rcov::RcovTask.new(:tests) do |t|
    t.libs << 'test'
    t.test_files = FileList['test/unit/*_test.rb','test/functional/*_test.rb','test/unit/helpers/*_test.rb']
    t.rcov_opts = rcov_opts
    t.output_dir = "coverage.tests"
  end

  desc 'Measures all coverage'
  task :all do
    ["features", "tests"].each{ |task| Rake::Task["rcov:#{task}"].invoke }
  end
end
