RCov with RSpec-2

I'm working with a bit of a bleeding edge rails app.开发者_开发问答 Rails 3, RSpec 2, Rspec-Rails2.

It seems as if RSpec2 doesn't include the spec:rcov rake task that RSpec 1 has. (at least it isn't there yet)

Has anyone had any luck running rcov with rspec 2, or writing their own rake task to make this work?

Try passing in options to exclude the gem directory. Or since your running rails use the rails flag:

desc  "Run all specs with rcov"
RSpec::Core::RakeTask.new(:rcov => spec_prereq) do |t|
  t.rcov = true
  t.rcov_opts = %w{--rails --exclude osx\/objc,gems\/,spec\/,features\/}
end

If you happen to be on Ruby 1.9x, I just got CoverMe (an rcov-ish lib that works under 1.9) working. Snappy and works out of the box w/ RSpec -- pretty much a plug-n-play setup. It just silently does your /coverage stuff every time you run rake:spec. Thought I'd mention it since I'm running 1.9.2preview3 on my bleeding edge stuff and it's possible you'll run into some 1.9 issues if you're using it.

We use simplecov at work, and find it easy and effective. I find it to be a cleaner solution than modifying rspec source directly, especially when you have CI servers to worry about.

Came up with this -

1) Open ~/.rvm/rubies//lib/ruby/gems//gems/rspec-rails-2.XXXXX/lib/rspec/rails/tasks/rspec.task in your favorite editor.

2) Add this rake task

desc  “Run all specs with rcov”
RSpec::Core::RakeTask.new(:rcov => spec_prereq) do |t|
  t.rcov = true
end

One outstanding problem. it runs rspec on every spec in both my rvm install folder and the project i'm in when i run the task. I can't figure out how to exclude all those rvm install tests. If anyone has an idea please let me know.
