I’ve been trying to find out if Rails 4.2 provides a single command that regenerates config/application.rb in an existing application.
I’m trying to find something more lightweight than running ‘rails new MyApp’ in a new directory and copying over the file.
The reason I ask is imagine a Rails app is ‘rails new’-ed without the --skip-test-unit option.
Then at a much later date, this app is switched to RSpec. Can config/application.rb be regenerated as if the --skip-test-unit option had been supplied originally to ‘rails new …’?
All this would effectively do is change the require statements near the top of config/application.rb file from:

Which asks if you want to overwrite config/application.rb and generates a new copy. However, I’ve not been successful in getting that command to make use of the --skip-test-unit option. I’ve tried variations on this without luck:
Many thanks in advance for any help,
