Aggregated RSpec/Cucumber test coverage with RCov

With defaults, RCov doesn't work the way you how you would like it to. To create a nice test coverage report, copy the attached file to lib/tasks/rcov.rake. After that rake rcov:all will run all RSpec examples and Cucumber features. The report will be written RAILS_ROOT/coverage/index.html.

Here is what the task does in detail:

• Generates aggregated coverage of both RSpec and Cucumber
• Works with Rails 2 and Rails 3
• Reports for app/**/*.rb and nothing else
• If called with an environment variable IGNORE_SHARED_TRAITS=true it ignores Modularity Show archive.org snapshot traits in app/controllers/shared and app/models/shared (which may or may not be entirely correct for your case).
• Tested that it works with Selenium features
• Doesn't add rake tasks outside development environment
