Webrat Webrat

Firefox, Chrome and HTML5 let you have a file field like this:

That will trigger the browser to select multiple files.
However Webrat does not support testing this feature.

To mske it work (on server side) the name must end with "[]" indicating an array value is expected.

I have made an ugly monkey patch (against 0.7.1) to make things work, here it is:
module Webrat class FileField def test_uploaded_file return "" if @original_value.blank?

      case Webrat.configuration.mode
      when :rails
        if Array === @original_value  ###THIS IS NEW
          @original_value.enum_for(:each_with_index).collect do |ov, i|
            if content_type[i]
              ActionController::TestUploadedFile.new(@original_value[i], content_type[i])
            else
              ActionController::TestUploadedFile.new(@original_value[i])
            end
          end
        else
          if content_type
            ActionController::TestUploadedFile.new(@original_value, content_type)
          else
            ActionController::TestUploadedFile.new(@original_value)
          end
        end
      end
    end
  end

  class Form
    protected

    def self.replace_param_value(params, oval, nval)
      output = Hash.new
      params.each do |key, value|
        case value
        when Hash
          value = replace_param_value(value, oval, nval)
        when Array
          value = value.map { |o| o == oval ? nval : ( o.is_a?(Hash) ? replace_param_value(o, oval, nval) : o) }
          value.flatten!(1) if Array === nval ###THIS IS NEW
        when oval
          value = nval
        end
        output[key] = value
      end
      output
    end
  end
end

Hope this will be part of webrat.
