I had troubles to get rcov working with the latest rspec2 release (since beta23 and now 2.0.0.rc). I got the same error every time: [bash] require': no such file to load -- spec\_helper (LoadError) [/bash] But luckily, somebody [found the problem](http://github.com/rspec/rspec-core/issues/issue/172) and it is extremely easy to fix. Just add -Ispecto your rcov task. Therake spec:rcovdoes not work for me (as it needs to be fixed). So i added my own task (add this code to the end ofRakefileor add in a seperate filercov.rakeinsidelib/tasks`) : [ruby] desc "Run all specs with rcov" RSpec::Core::RakeTask.new("test_cov") do |t| t.rcov = true t.rcov_opts = %w{--rails --include views -Ispec --exclude gems/,spec/,features/,seeds/} end [/ruby] and then you can run the task by typing [bash] > rake test_cov [/bash] in your rails root folder.
