I'd like to start debugger in methods during rspec test. I know, I can do it in the spec (like in this question), I have --debug in my .rspec file. 
I'd like to put debugger in a methods that is under tests:
it "should be OK" do
    User.ok? should be_true
end
class User
    def ok?
        do_something
        debugger      #here is my breakpoint
        do_something
    end
end
When I do something similar to that example and run rspec (using rake spec or guard or rspec) the breakpoind doesn't work.
