我正在尝试测试 Goliath + Grape 应用程序，如下所示：

require 'em-synchrony/em-mongo'
require 'yajl/json_gem'
require 'goliath'
require 'grape'

class API < Grape::API
  version 'v1', :using => :path
  format :json

  resource 'categories' do
    # http://0.0.0.0:9000/v1/categories/
    get "/" do
      coll = env.mongo.collection('categories') #Connection Pool from Goliath ENV
      coll.find({})
    end
  end
end

class App < Goliath::API
  def response(env)
    API.call(env)
  end
end

这两个类位于一个名为 app.rb 的文件中。运行ruby ./app.rb -sv启动一个http://0.0.0.0:9000/v1/categories/可以完美运行的 goliath 应用程序，但在制作更复杂的端点之前需要 rspec。无论如何运行我得到的规范

未定义的局部变量或方法“app”

我无法摆脱：

$ bundle exec rspec spec/api_spec.rb
FFFF

Failures:

  1) App App GET /v1/categories get several categories of repositories by name
     Failure/Error: get "/v1/categories"
     NameError:
       undefined local variable or method `app' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x993eec4>
     # ./spec/api_spec.rb:9:in `block (4 levels) in <top (required)>'

api_spec 如下所示：

require 'spec_helper'

describe App do
  include Rack::Test::Methods

  describe App do
    describe 'GET /v1/categories' do
      it 'get several categories of repositories by name' do
        get "/v1/categories"
        last_response.status.should == 200
        JSON.parse(last_response.body)["name"].should == "Ruby Web Frameworks"
      end
    end
  end
end

更新 ：

将 app 方法添加到 spec/api_spec.rb ：

def app
    App
end

引发另一种错误：

  1) App App GET /v1/categories get several categories of repositories by name
     Failure/Error: get "/v1/categories"
     NoMethodError:
       undefined method `call' for App:Class
     # ./spec/api_spec.rb:13:in `block (4 levels) in <top (required)>'

更新

在 spec/api_spec.rb 中添加从 app 方法调用的 API 类：

def app
  API
end

得到undefined methodmongo'`：

Failures:

  1) App App GET /v1/categories get several categories of repositories by name
     Failure/Error: get "/v1/categories"
     NoMethodError:
       undefined method `mongo' for #<Hash:0xad5ea58>
     # ./app.rb:14:in `block (2 levels) in <class:API>'
     # ./spec/api_spec.rb:13:in `block (4 levels) in <top (required)>'

见coll = env.mongo.collection('categories')内部 API 类

我终于能够使用goliath test_helper使其工作。这是为了跟踪目的，希望它可以帮助别人。

在 spec/spec_helper.rb 添加 goliath 测试助手和所有依赖项。就我而言：

require 'em-synchrony/em-http'
require 'goliath/test_helper'
require 'yajl/json_gem'

Goliath.env = :test

RSpec.configure do |c|
  c.include Goliath::TestHelper, :example_group => {
    :file_path => /spec\//
  }
end

在规范/app_spec.rb

require 'spec_helper'
require File.join(File.dirname(__FILE__), '../', 'app')

describe App do
  def config_file
    File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'app.rb'))
  end

  let(:api_options) { { :config => config_file } }

  it 'renders ' do
    with_api(App, api_options) do
      get_request(:path => '/v1/categories') do |c|
        resp = JSON.parse(c.response)
        categories = resp.map{|r|r['name']}
        categories.to_s.should =~ /Ruby Web Frameworks/
      end
    end
  end
end

Goliath 应用程序目录树，如下所示：

lsoave@ubuntu:~/rails/github/GGM$ ls -l 
total 48
-rw-rw-r-- 1 lsoave lsoave  483 Feb 25 23:06 app.rb
-rw-rw-r-- 1 lsoave lsoave 6321 Feb 25 23:06 categories.json
drwxrwxr-x 2 lsoave lsoave 4096 Feb 25 23:06 config
-rw-rw-r-- 1 lsoave lsoave  381 Feb 25 23:06 Gemfile
-rw-rw-r-- 1 lsoave lsoave 2293 Feb 25 23:06 Gemfile.lock
-rw-rw-r-- 1 lsoave lsoave   59 Feb 21 20:37 Procfile
-rw-rw-r-- 1 lsoave lsoave  123 Feb 25 23:06 Rakefile
-rw-rw-r-- 1 lsoave lsoave 7003 Feb 21 20:37 README.md
-rw-rw-r-- 1 lsoave lsoave  238 Feb 25 23:06 README.mongoimport
drwxrwxr-x 2 lsoave lsoave 4096 Feb 25 23:23 spec
lsoave@ubuntu:~/rails/github/GGM$

其中 config 和 spec 子目录如下所示：

lsoave@ubuntu:~/rails/github/GGM$ ls -l config spec
config:
total 4
-rw-rw-r-- 1 lsoave lsoave 870 Feb 25 23:06 app.rb

spec:
total 11
-rw-rw-r-- 1 lsoave lsoave  777 Feb 25 23:06 app_spec.rb
-rw-rw-r-- 1 lsoave lsoave  218 Feb 25 23:06 spec_helper.rb
lsoave@ubuntu:~/rails/github/GGM$

主要的 goliath 应用程序与我的第一篇文章相同：

require 'em-synchrony/em-mongo'
require 'yajl/json_gem'
require 'goliath'
require 'grape'

class API < Grape::API
  version 'v1', :using => :path
  format :json

  resource 'categories' do
    # http://0.0.0.0:9000/v1/categories/
    get "/" do
      coll = env.mongo.collection('categories') #Connection Pool from Goliath ENV
      coll.find({})
    end
  end
end

class App < Goliath::API
  def response(env)
    API.call(env)
  end
end

最后非常简单。如果您想深入了解，请查看https://github.com/lgs/GGM。

我认为您必须在测试中提供一种方法来指定您的应用程序的类

def app
  App
end

更新

改用 API 类

def app
  API 
end

添加其他 POST 示例：

require 'spec_helper'

describe V1::API do
  it "login" do
    with_api V1::Login do


      post_request(path: "/v1/login", :head => {'authorization' => HTTP_BASIC_HEADER }, :body =>{mobile: 18600112233}) do |async|

        async.response_header.status.should == 201
        async.response.should == { mobile: '18600112233' }.to_json
      end
    end
  end

end
