Capybara :: ElementNotFound:无法找到文件字段"file"

Question

我正在测试文件上传即CSV.在我的代码以及浏览器HTML中,我找到了文件字段,但在测试capybara时无法找到文件字段.我努力尝试不同的方法,但无法解决问题.这部分看起来像这样:

#add_file_box
  %div.msg
  %h1.page-header
    = "Upload a CSV"
  %h4.title

  = form_tag dummy_path, multipart: true, class: "upload_csv" do
    = hidden_field_tag :dmp_id, @dmp.id
    .form-group
      .input-group
        %span.input-group-btn
          %span.btn.btn-primary.btn-file
            Choose file
            = file_field_tag :file, style: 'line-height: normal',  accept: "text/csv", class: "file_input"
        %input.form-control.input-custom{:readonly => "", :type => "text"}
    .form-group
      = submit_tag "Upload CSV", class: "btn btn-primary", id: "upload_csv"

而且水豚测试看起来像这样

 within '.upload_csv' do
     page.attach_file('file', "#{Rails.root}/spec/acceptance/test_uploads/input_output.csv")
     click_button 'Upload'
   end

如果你能帮助我解决这个问题,我将感激不尽？

Answer 1

Capybara 2x(水豚问题)默认情况下找不到隐藏的元素.

您可以将ignore_hidden_​​elements设置为false:

Capybara.ignore_hidden_elements = false

或者只需在方法中添加:visible选项:

within '.upload_csv' do
  attach_file('file', "#{Rails.root}/spec/acceptance/test_uploads/input_output.csv", visible: false)
    click_button 'Upload'
end

这解决了我的问题.

注::visible选项也被大多数的水豚方法,在内部与工作的支持Capybara::Query(如find,all,has_css?,have_selector等)
