rspec-rails issue 2481

This is another demo of the issue reported as rspec-rails#2481

Reproduction steps

To reproduce:

1. Clone this repo
2. Run bundle install
3. Run bundle exec rspec

Observed behavior

The demo.html.erb_spec.rb view spec fails on a NameError for the example_helper_method helper.

This method is defined in DemoController using helper_method.

When running the server, the helper method works as expected.

But in the view spec, the helper cannot be found. The output is this:

bundle exec rspec
