describe 'Page without plans' do
  it 'passes unless a second assertion is made that .plans li contains at least one element' do
    visit root_path

    all('.plans li').each do |node|
      expect(node.text).to match /\$\d{1,2}/
    end
  end
end

There are times when an expectation may not get run - it may be called when iterating over items or something even crazier. Is there a way for this to fail if no expectation is called without changing the body of the it block?
