    Metadata details:

      def test_filter_fo
    
      def test_filter_field_as_select
        @output_buffer = filter_form url: "/" do |f|
          f.filter_field :foo, as: :select, collection: -> { %w(Foo Bar) }
        end

        assert_select "label[for=foo]", 1, "No label was found"
        assert_select "select[name=?]", "filter[foo]", 1, "No select found with name foo" do
          assert_select "option", 3
