I'm learning RSpec for a while and reading some articles, books and other resources. But I wonder if is there any complete real life Rails project, that using RSpec, with source codes available to examine. I study some gems and Ruby projects but still I think it would be better to see a Rails project's source code in action.
Discourse is a large, real world project you could take a look at.
They use RSpec and you can view all their testing code here.
