如何为XML方法设置Rails集成测试?

在集成测试中结合使用format和assert_select非常有效:

class ProductsTest < ActionController::IntegrationTest
  def test_contents_of_xml
    get '/index/1.xml'
    assert_select 'product name', /widget/
  end
end

有关更多详细信息,请查看 assert_select 在Rails文档中。

class TruckTest < ActionController::IntegrationTest
  def test_new_truck
    paint_color = 'blue'
    fuzzy_dice_count = 2
    truck = Truck.new({:paint_color => paint_color, :fuzzy_dice_count => fuzzy_dice_count})
    @headers ||= {}
    @headers['HTTP_ACCEPT'] = @headers['CONTENT_TYPE'] = 'application/xml'
    post '/trucks.xml', truck.to_xml, @headers
    #puts @response.body
    assert_select 'truck>paint_color', paint_color
    assert_select 'truck>fuzzy_dice_count', fuzzy_dice_count.to_s
  end
end

如果 标题是正确的。第三个参数@headers是我花了大量研究才弄明白的部分。

(请注意,在比较assert_select中的整数值时,使用to_s。)

class ProductsControllerTest < ActionController::TestCase
  def test_should_get_index_formatted_for_xml
    @request.env['HTTP_ACCEPT'] = 'application/xml'
    get :index
    assert_response :success
  end
end

这两个答案都很好,只是我的结果包括datetime字段,这在大多数情况下是不同的,所以 assert_equal 失败。看来我需要处理include @response.body

设置请求对象接受标头:

@request.accept = 'text/xml' # or 'application/xml' I forget which

然后,您可以断言响应主体与您期望的内容相同

assert_equal '<some>xml</some>', @response.body
