机架测试失败:JSON 请求尚无响应 [英] Rack test fails: No response yet for JSON request

问题描述

我正在尝试按照 Yehuda 中提供的 Ticketee 示例为我的 Ruby 项目创建 JSON APIKatz 的书 Rails 3 in Action，第 13 章.这是第 353 页描述的 RSpec 测试，适用于我的环境.

I am trying to create a JSON API for my Ruby project following the Ticketee example provided in Yehuda Katz's book Rails 3 in Action, chapter 13. Here is an RSpec test described on page 353 adapted to my environment.

# /spec/api/v1/farms_spec.rb # Reduced to the minimum code.
require "spec_helper"
include ApiHelper # not sure if I need this

describe "/api/v1/farms", type: :api do
    context "farms viewable by this user" do
        let(:url) { "/api/v1/farms" }
        it "json" do
            get "#{url}.json"
            assert last_response.ok?
        end
    end
end

当我运行测试时，我得到以下输出......

When I run the test I get the following output ...

$ rspec spec/api/v1/farms_spec.rb
No DRb server is running. Running in local process instead ...
Run options: include {:focus=>true}

All examples were filtered out; ignoring {:focus=>true}
  1) /api/v1/farms farms viewable by this user json
     Failure/Error: assert last_response.ok?
     Rack::Test::Error:
       No response yet. Request a page first.
     # ./spec/api/v1/farms_spec.rb:30:in `block (3 levels) in <top (required)>'

Finished in 2.29 seconds
1 example, 1 failure

这是我使用的辅助模块...

Here is the helper module I use ...

# /support/api/helper.rb
module ApiHelper
    include Rack::Test::Methods

    def app
        Rails.application
    end
end

RSpec.configure do |config|
    config.include ApiHelper, type: :api
end

注意:这个问题类似于使用 Rspec 和 Rack::Test 测试 REST-API 响应.

推荐答案

Rspec-rails 似乎忽略了 describe 块的 type: :api 参数并将/spec/api 中的所有规范视为请求规范(请参阅此处的请求规范一章).也许不推荐使用类型参数?我还没有找到它的任何文档..

Rspec-rails seems to ignore the type: :api parameter of the describe block and treats all specs in /spec/api as request specs (see chapter request specs here). Maybe the type-parameter is deprecated? I haven't found any documentation for it yet..

当使用 type: :request 而不是 type: :api 时，我可以让你的示例工作.我还删除了 app-method，因为它默认已包含在 RequestExampleGroup 中.

I can get your example to work when using type: :request instead of type: :api. I also removed the app-method as it's already included in the RequestExampleGroup by default.

# /support/api/helper.rb
module ApiHelper
    include Rack::Test::Methods
end

RSpec.configure do |config|
    config.include ApiHelper, type: :request
end

规范:

#/spec/api/v1/farms_spec.rb 
require "spec_helper"

describe "/api/v1/farms" do
    context "farms viewable by this user" do
        let(:url) { "/api/v1/farms" }
        it "json" do
            get "#{url}.json"
            assert last_response.ok?
        end
    end
end
