如何使用Capybara测试S3直接上传？

Question

I'm using s3_direct_upload for video uploading direct to S3. The user visits the page, clicks a div which is a proxy for clicking the form input, selects a file, hits 'ok', and then completes a form while the video uploads. I'd like to test this with capybara, but it's looking like I'll need to resort to #attach_file . Is this my only option?

In the capybara spec, I ended up going with the less-than-desirable approach of:

find(:css, '#choose-file').click

where my HAML has:

.choose-files
  = s3_uploader_form callback_url: videos_url,
    callback_param: 'video[direct_upload_url]',
    id: 's3-uploader',
    expiration: 24.hours.from_now.utc.iso8601,
    max_file_size: 100.megabytes,
    acl: 'public-read' do
    .small.button#choose-file{data: {upload: 'button'}} Choose File
    .hide
      = file_field_tag :file, multiple: true, id: 'upload-input'
    - content_for :javascript do
      :coffee
         $ ->
           $('#s3-uploader').S3Uploader
             remove_completed_progress_bar: false
             progress_bar_target: $('#uploads_container')
