使用rspec和Airborne進行JSONAPI測試

Question

您好，我在用rspec和空降測試JSONAPI時遇到問題。 GET模型位於https://i.stack.imgur.com/Cyf75.png

我以這種方式進行測試https://i.stack.imgur.com/Y9rHt.png

Rspec輸出：

失敗：1）/ contacts上的GET應該驗證類型失敗/錯誤：Expect_json（'books.0'，標題：'The Great Escape'）

 Airborne::PathError:
   Expected NilClass
   to be an object with property 0

Answer 1

您的API響應沒有關鍵books 。 相反，它以{ "data": [ ... ] }形式返回響應。

因此，在測試中，您需要指定expect_json('data.0', ...) ，而不是expect_json('books.0', ...) 。

希望能解決這個問題。

Answer 2

已經解決：

describe Api :: UsersController確實描述了'在/ users上獲取'，然后才做FactoryGirl.create（'user'，名稱：'Jack McClure'）FactoryGirl.create（'user'，名稱：'Johny Reaper'）FactoryGirl.create（ '用戶'，名稱：'Niko Bellic'）結束

it 'should return valid user' do
  get :index, format: 'json'
  expect_json('data.0.attributes', name: "Jack McClure")
  expect_json('data.2.attributes', name: 'Niko Bellic')
end
