Question

你好我用rspec和空中测试JSONAPI有问题。 GET模型如下 https://i.stack.imgur.com/Cyf75.png

我用这种方式测试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（＆＃39; books.0＆＃39;，标题：＆＃39; The Great Escape＆＃39;）

 Airborne::PathError:

Answer 1

您的API响应没有密钥books。相反，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', ...)。

希望能解决这个问题。

Answer 2

已经解决：

描述Api :: UsersController 描述＆＃39; GET on / users＆＃39;做之前做 FactoryGirl.create（＆＃39;用户＆＃39;，名称：＆＃39; Jack McClure＆＃39;） FactoryGirl.create（＆＃39;用户＆＃39;，名称：＆＃39; Johny Reaper＆＃39;） FactoryGirl.create（＆＃39;用户＆＃39;，名称：＆＃39; Niko Bellic＆＃39;）端

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

使用rspec和Airborne进行JSONAPI测试
