Capybara tests on a Rails Engine

If you have a Rails Engine you probably have a dummy app attached in test/dummy or spec/dummy to run and manual test the engine, right?

So you can use this dummy app to have some feature tests with capybara.

The trick is to change the RAILS_ROOT to point to the correct file.

For cucumber tests add the following into features/support/env.rb:

ENV["RAILS_ROOT"] ||= File.expand_path(File.dirname(__FILE__) + '/../../spec/dummy')

For rspec tests add the following into spec/rails_helper.rb:

ENV["RAILS_ROOT"] ||= File.expand_path(File.dirname(__FILE__) + '/dummy')
