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 method
mongo'`:
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
