Rake stats and Cucumber

I'm using Cucumber with RSpec in a Rails project. When I use the "rake stats" task, I get the following :

+----------------------+-------+-------+---------+---------+-----+-------+
| Name                 | Lines |   LOC | Classes | Methods | M/C | LOC/M |

So rspec adds its stats (see the model, view, controller and helper specs).

But I don't have the cucumber ones. How could I add them to my rake stats ?

RSpec creates a lib/tasks/rspec.rake file. And redefines the stats directories inside of it.

At the line 108 of that file, you'll see :

# Setup specs for stats
task :statsetup do
    require 'code_statistics'
    ::STATS_DIRECTORIES << %w(Model\ specs spec/models) if File.exist?('spec/models')
    ::STATS_DIRECTORIES << %w(View\ specs spec/views) if File.exist?('spec/views')
    ....
end

You just need to add your cucumber features directory there, right before the end of the task.

#
# Adding Cucumber features to the stats
#
::STATS_DIRECTORIES << %w(Cucumber\ features features) if File.exist?('features')
::CodeStatistics::TEST_TYPES << "Cucumber features" if File.exist?('features')

Why monkey patch the gem like that? You'll have to add your fix for it every time you update rspec-rails. Just extend the task locally with something like this:

echo "# Adding Cucumber features to be reported by the command:
# rake stats
# But e.g. in production environment we probably don't have rspec-rails, nor it's
# statsetup task, we could extend. So lets check if stasetup is available and only
# then extend it. If it isn't then just do nothing.
if Rake::Task.task_defined? 'spec:statsetup'
  Rake::Task['spec:statsetup'].enhance do
    require 'rails/code_statistics'
    ::STATS_DIRECTORIES << %w(Cucumber\ features features) if File.exist?('features')
    ::CodeStatistics::TEST_TYPES << 'Cucumber features' if File.exist?('features')
  end
end" > lib/tasks/cucumber_stats.rake

And FYI Lichtamberg and Damien MATHIEU this works just fine with rspec 2. However these rails specific rake tasks are ofc not part of the rspec gem itself, but a part of the rspec-rails gem.

P.S. This all was tested with ruby 1.9.2p180 (2011-02-18 revision 30909) [i686-linux], rails 3.0.8, rspec 2.6.0 and rspec-rails 2.6.1 and it might or might not work older versions of them.

Here's a version that works with Turnip and RSpec 2

I copy paste my custom set up for RSpec 1:

Although this is an extremely old question, it is still first when googling "rails rake stats cucumber" and the answers are misleading or outdated.

For future googlers, all you need to do is run

$ rails generate cucumber:install

This will create the necessary files, and specifically the lib/tasks/cucumber.rake file, which adds "Cucumber Features" to the rake stats output.
