使用rspec和机载进行JSONAPI测试

Question

您好，我有问题测试JSONAPI与rspec和空降。获取低于https://i.stack.imgur.com/Cyf75.png的模型

我是这样测试的，https://i.stack.imgur.com/Y9rHt.png

Rspec输出：

失败: 1) GET on /contacts应验证类型失败/错误: expect_json('books.0'，标题：'The Great Escape')

 Airborne::PathError:

Answer 1

您的接口响应没有密钥books。取而代之的是，它将响应返回为{ "data": [ ... ] }。

因此，在测试中，您需要指定expect_json('data.0', ...)，而不是expect_json('books.0', ...)。

希望这能解决这个问题。

Answer 2

已通过以下方式解决：

describe Api::UsersController do describe 'GET on /users‘do FactoryGirl.create('user'，name：'Jack McClure') FactoryGirl.create('user'，name：'Johny Reaper') FactoryGirl.create('user'，name：'Niko Bellic')结束

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

结束
