[rspec-users] Problems with RCov and Rails

[Ian Leitch]

Hey list,

I'm trying to use the rcov integration that rspec provides in my Rails
application. As per the  documentation on the website, I've created
the following rake task:

lib/tasks/specs_with_rcov.rake:

require 'spec/rake/spectask'

desc "Run all specs with rcov"
Spec::Rake::SpecTask.new('specs_with_rcov') do |t|
  t.rcov = true
end

However...

$ rake specs_with_rcov
(in /Users/ian/Projects/systino/trunk)
rake aborted!
superclass mismatch for class Annotation
/Users/ian/Projects/systino/trunk/rakefile:10
(See full trace by running task with --trace)

The Annotation class inherits a Struct instance which I thought may be
conflicting with a Struct class provided by RSpec, however it doesn't,
nor does RSpec contain an Annotation class. I'm afraid this bug is
beyond me. Has anyone else seen it?
