RSpec for Rails 5+

RSpec::Rails::ViewExampleGroup::ExampleMethods#render

Delegates to ActionView::Base#render, so see documentation on that
for more info.

The only addition is that you can call render with no arguments, and
RSpec will pass the top level description to render:

    describe "widgets/new.html.erb" do
      it "shows all the widgets" do
        render # => view.render(:file => "widgets/new.html.erb")
        # ...
      end
    end
