机架测试失败：JSON 请求尚未响应

Question

我正在尝试按照Yehuda Katz 的书《Rails 3 in Action》第 13 章中提供的Ticketee示例为我的 Ruby 项目创建一个 JSON API 。这是第 353 页上描述的适合我的环境的 RSpec 测试。

# /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......

$ 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

这是我使用的帮助模块......

# /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：此问题类似于使用 Rspec 和 Rack::Test 测试 REST-API 响应。

Rspec-rails 似乎忽略了type: :api描述块的参数，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）。也许类型参数已被弃用？我还没有找到任何相关文档..

type: :request我可以让你的例子在使用而不是使用时工作type: :api。我还删除了应用程序方法，因为默认情况下它已包含在 RequestExampleGroup 中。

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

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

和规格：

#/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
