rcov outside rails

Question

This may seem obvious but I don't find a way to run Rcov or coverMe outside a Rails project. I would like to use it with Rspec 2.5 I am using Ruby 1.9.2 so I guess this may be the problem.

I also would like not to use rake tasks but a command on the command line. I have tried several things and the best result I got is Rcov report for :

/var/lib/gems/1.9.1/gems/rcov-0.9.9/lib/rcov/code_coverage_analyzer.rb

and

/var/lib/gems/1.9.1/gems/rcov-0.9.9/lib/rcov/code_coverage_analyzer.rb

No idea why

Did you mean to repeat `/var/lib/gems/1.9.1/gems/rcov-0.9.9/lib/rcov/code_coverage_analyzer.rb`? — Andrew Grimm, Feb 28 '11 at 02:54
I meant, the coverage/ directory only have data about these two files — Jordi, Feb 28 '11 at 03:03

Check out http://ruby-toolbox.com/categories/code_metrics.html for some alternatives to RCov if using Ruby 1.9 is the problem.

The latest available version of rcov (0.9.8) still doesn't have good support for 1.9.2. You can try to run it on your project by doing:

 rcov spec/*.rb

But you'll most likely get something like:

 ** WARNING: Ruby 1.9 Support is experimental at best. Don't expect correct results! **

And then some errors after that.
