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

Question

我想知道测试带有动态ID的link_to内部的link_to单击的最佳方法是什么？

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

我的桌子会这样填充

%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}"

提前致谢
