testing - 没有使用 Rspec 的请求规范的回溯

Question

我有这样的请求规范

require 'rails_helper'

describe 'People API' do

  describe 'GET /api/v1/people/lookup.json?phone_number=PHONE_NUMBER', :wip do
    it 'returns a 200 status code' do
      auth_get '/api/v1/people/lookup.json', phone_number: '91900199'
      expect(response.status).to eq(200)
    end
  end
end

如果规范由于某种原因失败，我只会在响应中得到一个 500 状态代码，仅此而已，所以我必须检查 log/test.log 文件以了解是什么出错了，这很烦人。

为什么 rspec 不像其他类型的规范那样显示回溯？

这是我运行规范的方式，请注意我包含了 -b 选项

$ rspec -b -t wip -f documentation                                                                                                                                                                                                                                                                     
Run options: include {:wip=>true}

People API
  GET /api/v1/people/lookup.json?phone_number=PHONE_NUMBER
    returns a 200 status code

Failures:

  1) People API GET /api/v1/people/lookup.json?phone_number=PHONE_NUMBER with an empty phone number returns a empty response
     Failure/Error: expect(response.status).to eq(200)

       expected: 200
            got: 500

但是没有包含500错误的真正原因

Answer 1

您的请求规范与您的整个堆栈交互，包括中间件。当您的某个 Controller 方法内部发生错误时，它会在堆栈的较高位置被捕获，以便可以将 500 错误返回给客户端。这就是您在断言失败中看到的。

您可以编写自己的中间件用于测试目的，如果您确实需要，它会将错误打印到 stderr。
