RCov with RSpec-2

Question

I'm working with a bit of a bleeding edge rails app. 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?

rspec-rails-2.0.0.rc has this task in the rspec rake file. – wesgarrison Nov 02 '10 at 03:23 — wesgarrison, Nov 02 '10 at 03:23

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

Where's this supposed to live? – Aupajo Aug 19 '10 at 05:24

@Aupajo: From JoshReedSchramm answer below where he had an earlier iteration of this answer, he put it in `~/.rvm/rubies//lib/ruby/gems//gems/rspec-rails-2.XXXXX/lib/rspec/rails/tasks/rspec.task` – wesgarrison Nov 02 '10 at 03:20

Well and what about when I can't change gem contents? I need to run test coverage on Jira-Bamboo build server :( – Dalibor Filus Oct 04 '11 at 12:35

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.

Today (8/21/2012) this is pretty much the right answer. At the time this question was posed rspec2 was new, simplecov really didn't exist yet. – JoshReedSchramm Aug 22 '12 at 00:37

simplecov works only in 1.9.*. rcov works only in 1.8.*. you can't really use simplecov if you are on 1.8 – yiwen Oct 26 '12 at 21:07

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.
