我想用 rspec 测试 API 控制器.所以这是一段简单的代码:

I want to test API controller with rspec. So here is the simple piece of code:

require 'rails_helper' describe "GET /api/config" do it 'routes GET to /api/config to Api::V1::ConfigsController#show' do get '/api/config.json' expect(response).to be_success end end

但是我有一个错误:

1) Configs API GET /api/config routes GET to /api/config to Api::V1::ConfigsController#show Failure/Error: expect(response).to be_success NameError: undefined local variable or method `response' for #<RSpec::ExampleGroups::ConfigsAPI::GETApiConfig:0x007f84d93fbb90> # ./spec/routing/api/v1/devise/configs_routing_spec.rb:13:in `block (3 levels) in <top (required)>'

推荐答案

在 RSpec 3 中，你会这样做:

In RSpec 3 you would do:

get '/api/config.json' expect(response.status).to be(200)

您缺少的是 describe 块中的类型声明，即:

What you're missing is a type declaration in your describe block, ie:

describe "GET /api/config", type: :controller do end
