Capybara::ElementNotFound: Unable to find file field “file”
问题 I am testing file upload i.e CSV. In my code as well as browser HTML I found file field but while testing the capybara is unable to find the file field. I tried hard and different approaches but unable to fix the problem. Here partial look like this: #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
