To run the tests:

• git clone git@github.com:merhard/rails-regression-testapp.git
• cd rails-regression-testapp
• bin/setup
• bin/rake test

To see the regression in a browser at http://localhost:3000/sub_uri:

• bin/rails s

If the Rails version is changed from v4.2.3 to v4.2.2, the test passes and the regression is not seen in the view.
