使用Capybara / Rspec / Rails4使用动态ID测试link_to

Question

I was wondering what would be the best way to test a click on a link_to inside of an iterated table with dynamic id?

scenario 'select customer from the list' do
  sign_in_with user
  visit customers_path
  ## and here I would like to fire this action
end

And my table would be populated as such

%table.table.table-striped
  %thead
    %tr
      %th
        Name
      %th

  %tbody
    - @customers.each do |customer|
      %tr
        %td
          = customer.name
        %td
          = link_to '', root_path, class: 'glyphicon glyphicon-usd pull-right', id: "customer_#{customer.id}"
          = link_to '', customer, class: 'glyphicon glyphicon-zoom-in pull-right', id: "customer_#{customer.id}"

Thanks in advance

Capybara will match the id the same as the text...

    @customer = Customer.all.sample
    click_link "customer_%d"%@customer.id
